Changes in KPC-NX/NC v8.3.7 and KPC-N v8.3.4 (30-03-2023)

  • Improvement (KPC-NC): Swipe and scroll animation improvements:
    • When scrolling a list of zones or sources, the scroll operation now smoothly moves to the final position. Previously the list would snap to the final position when the scroll movement stopped, which was irritating because it was unclear if the list had jumped up or down a line.
    • When swiping zone groupings horizontally or pages in any direction, previously the portion that moved off the page was lost so if the swipe direction was reversed, the area that moved back was empty. Now the original display contents are moved back.
    • When swiping zone groupings horizontally or pages in any direction, previously if the swipe did not move far enough then the page or zone grouping would just snap back into the original position. Now the page or grouping is moved smoothly back.
    • Swipe animations now show fewer update artefacts, particularly when swiping pages.
  • Correction (KPC-NC): It was previously possible to swipe left or right the zones page of the default "Nightfall" template without actually swiping a zone (e.g. by swiping the title area) resulting in unexpected behaviour. Now only the zone groupings can be swiped.
  • Improvement (KPC-NX/NC): Button label texts such as zone or source names that are too long for the buttons that they are placed on are now displayed as "marquee" texts.
  • Improvement: Added "Previous page" KPC command which enables macros and page swipe actions to return to the previous page. Requires next Axium Design Portal version (release pending).
  • Various improvements and corrections.

  • CHANGE: System firmware component now loaded into a different partition than what was originally used during firmware updates to avoid contention with large sound files (e.g. for doorbells/paging). If updating a firmware older than version 3.0.1 via USB please manually reboot the unit after the firmware upload has completed by removing and restoring power.
  • Various corrections and improvements.


Changes in AX-800-X v5.6 (23-01-2019)

  • CORRECTION (TuneIn radio, AX-800-X only): In extremely rare circumstances the built-in media player swapped to the next channel. This was happening more often recently possibly due to a change in server infrastructure of certain NZ local radio stations which exposed the issue.
  • CORRECTION: The amplifier was not able to initiate command execution on other Axium devices and attempting to do so would result in system instability (regression since v5.5).
  • Various improvements and corrections.


Changes in AX-Mini4 and AX-1250 v3.0.2 (19-12-2018)

  • CORRECTION (TuneIn radio): In extremely rare circumstances the built-in media player swapped to the next channel. This was happening more often recently possibly due to a change in server infrastructure of certain NZ local radio stations which exposed the issue.
  • CORRECTION (regression in 3.0.0): The restore defaults function did not clear out the zone and source names unless the amplifier was rebooted before changing other settings.


Changes in AX-AMM v1.1.12_rc1 (19-12-2018)

  • IMPROVEMENT: The handling of zones and groups displayed by the Spotify Connect/UPnP services has been improved so that various bugs and fringe case issues have been resolved/improved.
  • CORRECTION: Changing between streaming services could sometimes cause the streaming source to become inoperable. This was especially true when changing from using the Spotify Connect service to something else.
  • CORRECTION: Multiple Axium app controller connections simultaneously loading media players, may have triggered a hang with a couple of minutes of unresponsiveness before finally recovering.
  • Various improvements and corrections.


Changes in AX-Mini4 and AX-1250 v3.0.1 (13-12-2018)

  • CORRECTION (regression in 3.0.0): Doorbell sound playback was cut off or did not play if the source in the page preset was set to the media player source.
  • CORRECTION (regression in 3.0.0): The distributed source table uploaded from ADP was not loaded.
  • CORRECTION (regression in 3.0.0, AX-Mini4 only): The zone settings were not loaded from the old data structures used in earlier firmwares. This was due to the settings being added for the 4 band parametric EQ.
  • CORRECTION (AX-1250): Minor display errors on front panel display. Display refresh speed improved.
  • Various improvements and corrections.


Changes in AX-Mini4 and AX-1250 v3.0.0 (18-10-2018)

  • IMPROVEMENT: Backup and restore functionality for amplifier settings added to web interface on the Management page. Settings files are compatible across amplifier types. The internal storage of settings no longer uses firmware version dependent data structures so in future upgrading and downgrading between firmware versions will not result in the loss of settings.
  • IMPROVEMENT: Extended maximum length of zone and source names so now all those zone names like B-52 Stratofortress and Axium Interstellar Spaceport don't require abbreviation. Zone and source names were previously limited to only 15 characters when regular ASCII characters were used or fewer characters when using exotic characters, e.g. only 5 Chinese characters were previously possible.
  • IMPROVEMENT: Firmware update function added to the web interface. Also in the event that the web interface is lost (usually due to a failed firmware update), it is now possible to perform a new firmware update from the web browser for recovering full functionality.
  • IMPROVEMENT (AX-Mini4): Added 4 band parametric EQ to all zones. Use web interface to configure.
  • CHANGE: Presets now only set the 4 common settings, i.e. Power, Source, Volume and Mute. This rectifies a previous problem where a preset activation would inexplicably override settings such as bass/treble, maximum volume, mono, etc.
  • CORRECTION (AX-1250): If the corner frequencies of the 7 band parametric EQ were changed, these were not restored when the EQ page in the web interface was re-opened. The 7 band parametric EQ was added in v2.14.
  • CORRECTION: The amplifier was not able to initiate command execution on other Axium devices and attempting to do so would result in system instability (regression since v2.11).
  • Various improvements and corrections.


Changes in ADP v5.1 (17-05-2018)

  • IMPROVEMENT: Remote project uploads re-enabled.
  • CHANGE: All uploads now require that the project have a defined address for the system and that the address is not simply changed between jobs. Necessary for the remote uploads feature.
  • IMPROVEMENT: Added "project is a template" option to project properties for the case when a project has common elements and is frequently re-used between jobs as the basis for job specific projects.
  • IMPROVEMENT: Added more checks to the network test. Now handles and warns of the case when multiple devices have been programmed from the same ADP device. Also added consistency checks for the distributed source tables.
  • CORRECTION: Fixed a problem with variable monitor triggers which only used value specific actions.
  • CHANGE: Windows-XP is no longer supported.
  • IMPROVEMENT (KPC): added "reboot panel" command. Some other corrections (fw 7.9.2).


Changes in AX-Mini4 and AX-1250 v2.14 (16-05-2018)

  • IMPROVEMENT (AX-1250): Added 7 band parametric EQ to all zones. Use web interface to configure.
  • IMPROVEMENT: KNX upgrades with new datapoint assignments with support for 6 AMM media players.
  • CORRECTION (AX-1250): Delay and speed issues on preamp zones since version 2.13.
  • CORRECTION (Mini-4 v2): Audio received on the digital inputs was not correctly streamed to other amplifiers if the audio sample rate was not 48kHz.
  • CORRECTION: Automatic distributed source assignments could in some circumstances override manual assignments.
  • IMPROVEMENT: Added zone merging option to zone linking.
  • IMPROVEMENT: Distributed sources now supported in remote IR routing. If the source selection on an IR input's associated zone is a distributed source, then IR can now be directed at the source device (which is most likely remote to the amplifier). Also corrected various issues.
  • CORRECTION: Previously on power up the IR routing from IR inputs to IR outputs was undefined if there was no physical source selected on the IR input's associated zone.
  • IMPROVEMENT: Preset sounds (doorbell sounds) can now play without disrupting distributed source audio playing in zones where the preset sound is not played. (Useful if using the P2 input on the AX1250 as zones can be excluded from the preset.)
  • IMPROVEMENT: Network performance improvements to improve stability on busy networks. (Broadcast and multicast packet filtering, application polling schedule, checksum offload for RX, checksum calculation optimised for TX, TCP-ACK TX suppression if RX segments pending, ARP cache priority upgrade.)
  • Various web interface upgrades, new slider controls, parametric EQ set up on the AX-1250, new KNX interface option, merge zone option in zone linking, copy buttons for the logs in the config/management page.


Changes in AX-AMM v1.1.5 (22-03-2018)

  • CORRECTION: fixed issues that could occur affecting the Amazon cloud services integration. This would prevent Alexa from working properly.
  • Various bug fixes and improvements


Changes in ADP v5.0 (01-03-2018)

  • IMPROVEMENT: Added remote project uploading.
  • IMPROVEMENT: Added support for TIDAL streaming on the AMM.
  • IMPROVEMENT: Upgraded the analogue input level and frequency triggers in the R1/R4 designer. Voltage and frequency can be converted to other arbitrary values such as temperature or windspeed which can now be displayed using a variable on user interfaces. Upgrades require R1/R4 firmware update. Also added an applet that can adjust the on/off trigger threshold values.
  • IMPROVEMENT: Added compound triggers to the R1/R4 designer. These allow the inputs from multiple triggers to be combined, e.g. "whenever the voltage on input X is high AND it is night time then do ..."
  • IMPROVEMENT: Added buttons to action fields in the R1/R4 designer for creating typical actions.


Changes in AX-AMM v1.1.4 (27-02-2018)

  • IMPROVEMENT: Support for the TIDAL streaming service
  • IMPROVEMENT: Voice control with Amazon Alexa

  • IMPROVEMENT: Added remote project upload support. Requires ADP 5.0 or greater.


Changes in KPC-N v7.9 (05-12-2017)

  • CORRECTION: buttons with source selection button classes are now shown as active when the corresponding distributed source is selected.
  • IMPROVEMENT: Added remote project upload support. Requires ADP 5.0 or greater.


Changes in AX-Mini4 and AX-1250 v2.13 (04-12-2017)

  • IMPROVEMENT: Added remote project upload support. Requires ADP 5.0 or greater.
  • IMPROVEMENT: Reduced playback start threshold for internet radio.

  • CORRECTION: fixed a problem which caused TuneIn to temporarily go to "buffering" five minutes after opening the Axium mobile app. Also reduced playback start threshold.
  • Multiple corrections and improvements inherited from AX-1250 and AX-Mini4 development.


Changes in R4D/R1D v3.5, R4C v4.5 (28-09-2017)

  • IMPROVEMENT: analogue input triggers offer new features which will be available in ADP 4.9.
  • Improvement: implemented measures to work around IP address conflicts. Includes static IP address override in case of conflict.
  • Correction: one-time override schedule was cleared on activation and resulted in another activation by the normal schedule if the override was earlier than the normal schedule.
  • Improvement: schedule trigger with on and off actions now activate if the time suddenly is between the on and off times. This can happen if the device is reset (power reset, upload, etc), the schedule is changed or the current time is updated. Previously none of these events caused the trigger to activate and the next activation would only occur on the next day. This is not done for triggers with only an on action as these are likely to be used in an alarm clock role and a spontaneous reactivation hours after the activation time in the event of a power reset would be unwanted.
  • Correction: IP command match trigger matching on too many devices.
  • Correction: IR command matching failed for some rare cases.
  • Various other corrections and improvements


Changes in ADP v4.8.1 (29-08-2017)

  • CORRECTION: resolved some issues in the network test function.
  • Added new Integra receiver models to Integra receiver applet.


Changes in ADP v4.8 (24-05-2017)

  • IMPROVEMENT: added network test function for finding common network issues. Located in the Tools menu.
  • AMM improvements:
    • ​​​IMPROVEMENT: commands for selecting favourites and controlling media players can now be defined.
    • IMPROVEMENT: commands for controlling 3rd party amplifiers can now be set up for S/PDIF outputs. Useful for example when using Spotify and a "device" corresponding to an S/PDIF is selected then the amplifier connected to the S/PDIF output can be switched on and the appropriate input can be selected.
    • IMPROVEMENT: added integer and boolean variables with variable monitoring triggers.
  • CHANGE: zone 0 has been removed and zone 96 has been added.
  • IMPROVEMENT: added separate dim settings for night time mode on the KPC. Display reddening is now optional. Brightness settings now optionally uses logarithmic scale for more range between the maximum and minimum brightness levels. Requires KPC firmware 7.8.
  • CORRECTION: corrected issues with the Sonance iPort dock applet.
  • Added some new system button classes.
  • Added IR commands for Maranz receivers. Also added some new channel icons to the NZ Channels galleries.

Changes in KPC-N v7.8 (24-05-2017)

  • IMPROVEMENT: display brightness increased at maximum brightness. Added support for logarithmic brightness settings for more range particularly at darker settings for dim light levels.


Changes in AX-Mini4 and AX-1250 v2.12 (18-05-2017)

  • IMPROVEMENT: HTTPS audio streams are now supported. This became necessary for supporting Pandora when using iOS devices ever since Apple introduced a policy of enforcing the use of HTTPS instead of HTTP. Many internal improvements to make this work.
  • IMPROVEMENT: TuneIn metadata handling now handles the situation when some radio stations send the name of the track that is ending after sending the name of the next track that is about to begin. This behaviour always overwrote the name of the next track and caused the name of the previous track to be displayed for the duration of the following track.
  • IMPROVEMENT: UPnP extensions to allow Pandora and Local Music Library to be selected on distributed media player sources which are hosted by another amplifier not hosting the selected zone. An Axium mobile app will be released shortly that takes advantage of this feature. This improvement became more important since firmware 2.10, which automatically configures all sources (including media player sources) as distributed sources so that all amplifiers can access them.
  • CORRECTION: firmware downloads can now resume the download if the connection is closed, which was frequently occurring during the erase step for the AX-1250 firmware version 2.11 release due to the different behaviour of our new website provider's server. The firmware update could previously always be restarted but this was nevertheless causing some users to assume that their amplifiers were bricked.
  • CORRECTION: fixed a regression that was introduced in version 2.6.2 which caused incorrect audio delays to be set when setting the delays and when settings are restored on system reset (power up, etc).
  • CORRECTION: fixed a problem which caused TuneIn to temporarily go to "buffering" five minutes after opening the Axium mobile app.
  • CORRECTION: fixed a regression that was introduced 2.11 which stopped sources from being listed in the web application after they were disabled, which prevented them from being re-enabled.


Changes in AX-Mini4 and AX-1250 v2.11 (20-04-2017)

  • IMPROVEMENT: Upgraded web application. Now supports multiple browser tabs being open simultaneously.
  • CHANGE: zone 0 has been replaced with zone 96.
  • CHANGE: Amplifier media sources are now excluded from the auto distributed sources assignments if an AMM is found.
  • ​IMPROVEMENT: improved web application caching so future firmware updates do not require the browser cache to be cleared.
  • Improvement: implemented measures to work around IP address conflicts. Includes static IP address override in case of conflict.
  • ​CORRECTION: several bugs in the auto-zoning and auto distributed source assignments fixed. In some cases zone assignments in an upload from ADP were rejected if auto zoning was in progress when the upload occurred. Also in some cases manual distributed source assignments could be overwritten by automatic ones.
  • IMPROVEMENT (AX-1250): Tone control on preamp zones now more closely matches the characteristics of the amp zones. Also audio quality of digital inputs improved.


Changes in AX-400-X and AX-800-X v5.4 (28-03-2017)

  • IMPROVEMENT: Upgraded web application. Now supports multiple browser tabs being open simultaneously.
  • CHANGE: front panel GUI and web application now shows zone 96 instead of zone 0.
  • Improvement: implemented measures to work around IP address conflicts. Static IP address override in case of conflict is however not implemented.
  • Multiple corrections and improvements inherited from AX-1250 and AX-Mini4 development over the past year. Includes change to use IGMPv2 instead of IGMPv3, manually added favourites, corrected sound quality issues on some radio stations in TuneIn, fixed issues with Chinese or other exotic characters, improvements in TuneIn to list more radio stations, many web application improvements, etc.​


Changes in KPC-N v7.7 (13-03-2017)

  • IMPROVEMENT: implemented IP address conflict mitigation measures.
  • ​CHANGE: now shows zone 96 instead of zone 0.
  • ​CORRECTION: problem preventing re-connection with R4C/D or R1D if the last connection was established more than approx. 25 days previously.


Changes in AX-Mini4 v2.10.1 (22-12-2016)

  • CORRECTION: updating to version 2.10 from an earlier version reset zone and source settings back to defaults.


Changes in ADP v4.7 (19-12-2016)

  • IMPROVEMENT: AMM support added.
  • IMPROVEMENT: zones and sources can now be disabled on amplifier types that support this feature.
  • IMPROVEMENT: amplifier command editor improved and some bugs fixed. Added support for the new dynamically linked zones feature.
  • CHANGE: upload options for updating devices are now disabled until the device has either been uploaded to via USB or via the network with serial number.
  • CHANGE: zone 0 removed from the Axium database. This will be replaced with zone 96 at a later date.
  • CHANGE: Old template galleries removed in favour of the customisable and project oriented templates library.
  • Applets:
    • NEW axium alarm/preset applet for mobile app.
    • NEW arrowhead alarm applet for KPC and mobile app.
    • NEW iPort Dock SM Buttons applet for mobile app.

  • Various improvements and corrections.


Changes in KPC-N v7.6 (19-12-2016)

  • IMPROVEMENT: Internal upgrades for the Fibaro applet.
  • CORRECTION: IR learning did not handle some Cisco camera IR commands correctly.


Changes in AX-Mini4/1250 v2.10 (19-12-2016)

  • IMPROVEMENT: Sources from all AMM and amplifier devices in the system are now automatically configured as distributed sources. Manually configuring distributed sources disables this function to prevent unwanted assignments but it can be re-enabled by restoring default settings.
  • IMPROVEMENT: Web interface improvements. The device page now lists other AMM and amplifier devices and allows them to be configured.
  • CHANGE: IGMPv2 is now used. This seems to have more widespread support than IGMPv3, which was previously used.


Changes in AX-Mini4/1250 v2.9.1 (23-11-2016)

  • IMPROVEMENT: Favourites can now be manually added and edited in the web interface. This allows radio stations not listed in TuneIn to be played.

  • CORRECTION: fixed issues with Chinese or other exotic characters used in folder or file names on network shares.


Changes in R4D/R1D v3.4, R4C v4.4 (18-07-2016)

  • IMPROVEMENT: IR command match trigger can now match repeating IR commands and allow an IR action to auto-repeat as long as the incoming command continues to be received. Note that the match criteria are now stricter so invalid commands that may have previously matched may now fail to match.
  • IMPROVEMENT: added the read_time function for scripting.


Changes in KPC-N v7.5.1 (18-07-2016)

  • CORRECTION: pulsed IR commands (commands without modulation) caused a system crash.


Changes in ADP v4.5 (17-05-2016)

  • IMPROVEMENT: Added DALI device setup to the "Tools" menu. This function performs the DALI device configuration that previously required the use of an external tool. Basic DALI parameters are configured such as address, groups, scenes, minimum/maximum brightness, etc (non-standard DALI options still require software from the device manufacturer). Requires the use of an R1D or R4D connected via USB to the PC and connected via a DALI port to the DALI bus (with DALI power supply). The R1D/R4D firmware must be version 3.3 or higher.
  • IMPROVEMENT: Added settings for the auto power on / auto standby function available on the AX400-X. This also includes the optional ability to use a source for activating the page 1 and page 2 functions.
  • IMPROVEMENT: Added settings for configuring the digital outputs on the Mini4 amplifier. Requires firmware 2.5 or higher.
  • IMPROVEMENT: general improvements and simplifications in R1/R4 designer for managing variables, DALI objects and relays. For example added buttons to create DALI commands direct from a DALI lamp or group, can now drag variables, DALI objects and relays into action fields for creating a macro for setting the variable to a specified value.
  • IMPROVEMENT (KPC): Scheduled event setup applet improved to add support for
    • Schedule for off actions
    • Sunrise/sunset and timer modes. Cannot change mode, however, just edit time offsets.

  • CORRECTION: fixed problems caused when page selections made by external devices occurred when the screensaver page was active.


Changes in AX400-X v5.3 (10-05-2016)

  • IMPROVEMENT: Added auto power on / auto standby function. Audio detected on a zone's selected source will turn it on (auto power on) and when there is no audio for the selected timeout, the zone will turn off.


Changes in ADP v4.4 (13-04-2016)

  • IMPROVEMENT: Added Templates tab to the library browser. User templates can be added, this takes the current project and makes it into a template.
  • IMPROVEMENT: Firmware and ADP updates are now downloaded by ADP instead of using Windows to open a web browser to do this. This avoids problems with the web browsers displaying nonsense instead of downloading to a file, users getting confused because they expected ADP to somehow know where the browser downloaded the file to, ADP not knowing if the file was really downloaded and therefore not being able to update its version information.
  • IMPROVEMENT: The animation behaviour of unpinned docked windows has changed. The hide animation has been removed because a Windows bug caused some systems to leave artefacts on the display. There are now options in the menu "Tools" - "Preferences" - "Docking" - "Unpinned windows" for setting the animation speed when showing windows because the animation can be annoying.
  • CHANGE: The default macro delay and default transition animation settings are now in the project properties. The settings in the KPC and mobile app settings area have been removed.
  • IMPROVEMENT: support for new R4D/R1D features (see below).
  • CORRECTION: IR test function did not work on R4D/R1D firmware 3.2.1.
  • Mobile app:
    • IMPROVEMENT: added HDL and Fibaro lighting applets.
    • IMPROVEMENT: Variable monitor trigger now has value specific actions for boolean and integer variable types. This allows different actions to be performed depending on what state the variable changes to.
    • IMPROVEMENT: web view applet, added "video stream" mode currently fully functional on Android, iOS partially.
  • CHANGE: the term "remote source" has been replaced with "distributed source".
  • IMPROVEMENT: added "Copy" button to diagnostic log for copying the log contents to the clipboard.
  • Various corrections and improvements.


Changes in R4D/R1D v3.3, R4C v4.3 (13-04-2016)

  • IMPROVEMENT: New "relay" variable type. This is a boolean variable that directly controls the state of a relay on the device. The relay can optionally be controlled by DALI devices.
  • IMPROVEMENT: MSensor (movement) now has a timeout property. This allows it to be used as a human presence sensor without additional logic.
  • IMPROVEMENT: Variable monitor trigger now has value specific actions for boolean and integer variable types. This allows different actions to be performed depending on what state the variable changes to.
  • IMPROVEMENT: IR generation is now logged in the diagnostics log when comms logging is active
  • IMPROVEMENT: added support for the sleep instruction for scripting.
  • CORRECTION: fixed problem with IGMP causing some routers to generate excessive traffic.


Changes in Mini4 v2.4 (13-04-2016)

  • CHANGE: the term "remote source" has been replaced with "distributed source". Internal changes to improve synchronisation between amplifiers.
  • CHANGE: Reduced overall volume gain so maximum volume (when clipping occurs) is closer to 100% volume when input signal is at 0 dB. Note the zone gain function can be used to restore the original overall volume gain if that behaviour is preferred.
  • CORRECTION (TuneIn): supported audio formats now specified, which was necessary for obtaining a playable stream from some radio stations particularly in South Africa.


Changes in KPC-N v7.4 (12-04-2016)

  • CHANGE: the term "remote source" has been replaced with "distributed source".
  • CORRECTION: fixed problem with IGMP causing some routers to generate excessive traffic.

Changes in KPC-N v7.3 (17-12-2015)

  • IMPROVEMENT: Added IGMP support to be compatible with network switches using IGMP snooping.
  • IMPROVEMENT: previously many functions that relied on a network connection silently failed if there wasn't one. Now error messages appear on the display when a network connection is not available but one is required.


Changes in AX800-X and AX400-X firmware v5.2 (15-12-2015)

  • IMPROVEMENT (AX800-X only): Alias names for network shares.
  • IMPROVEMENT (AX800-X only): Added media favourites (use web application to set favourites).
  • IMPROVEMENT: Added amplifier commands which can be used in amplifier events, macros or called by other devices for controlling various amplifier functions.

  • CORRECTION: firmware upgrade enforcement false positives.
  • Various improvements and corrections


Changes in Mini4 v2.2, R4D/R1D v3.1, R4C v4.1 and KPC-N v7.2 (29-10-2015)

  • CORRECTION: multiple network upload issues


Changes in Mini4 v2.1 (15-10-2015)

  • IMPROVEMENT: added media player favourites. A TuneIn radio station or a folder in a network share can now be marked as a favourite and these will appear in a new entry in the root media player list called "Favourites". Notes:
    • Only the web application is currently able to add and remove favourites. This shows a button with a star shaped icon during playback when a favourite can be added or removed. The content is a favourite when the star is yellow. The web application also has an edit function in the config section under "Media".
    • On network shares, folders are marked as favourites rather than individual tracks.
    • Only TuneIn and network shares can be favourites, not local media on Android/iOS and not Pandora, as these are mobile app functions.
  • CORRECTION: in some cases the media player was occasionally muted for about 1 second.
  • IMPROVEMENT: sound quality improvements in outgoing remote source streams.
  • CORRECTION: uploads from ADP could get stuck in a loop and keep repeating.


Changes in Mini4 v2.0.1 (04-09-2015)

  • CORRECTION: problem saving the remote sources table in the web application.
  • IMPROVEMENT: added alias names for network shares.


Changes in ADP v4.1 (03-09-2015)

  • IMPROVEMENT: added remote source support. This includes:
    • Remote source table.
    • Button classes for KPC and Axium mobile app.
    • Renamable media player sources.
    • New Axium IR commands in the database.
    • Additional amplifier events fired on remote source selection.
  • IMPROVEMENT: added project properties section. Currently this is dominated by the remote source table.
  • IMPROVEMENT: when uploading over network, the IP and MAC addresses are now updated in the device network settings.
  • IMPROVEMENT: The "AMC window" used in the amplifier designer can now use a USB connection again. This was changed in v4.0 to prefer a network connection but now either type of connection can be used.
  • IMPROVEMENT: new button classes for the Axium mobile app for audio settings, accessing config section of web application, etc.
  • CHANGE: removed Integra Tuner and DLO Homedock KPC applets.
  • Various improvements and corrections.


Changes in Mini4 v2.0 (03-09-2015)

  • IMPROVEMENT: added remote source functionality. In a system with multiple Mini4 amplifiers, any zone can now play a source on any Mini4. Notes:
    • The remote sources must be set up before they can be used. This can be done using the web application (go to the /config section and select the sources page) or using ADP.
    • Up to 32 remote sources can be defined for a single system.
    • Previously all amplifiers used the same names for the same source inputs because they were typically installed as a stack. However now the amplifiers can be distributed around the house so this no longer necessarily applies. For this reason the sources can be set as "independent" and given names that are used only on that amplifier. The media sources can now also be renamed.
    • The remote source data streams are propagated on the network so all amplifiers which are to be involved must be connected to the same network. The data streams are not routable to other networks so in any complex networks they need to be on the same subnet. The network paths between amplifiers must all be wired.
    • Delays can be used with remote sources. If no delay is set up there is a very low latency of 5-10ms from the remote source input to the speaker output (the time it takes for sound to travel about 2 - 3 metres).
  • IMPROVEMENT: added auto-zoning. If multiple Mini4 amplifiers are installed without having their zones explicitly set using the web app or ADP, the Mini4 amplifiers will now negotiate and set themselves to unused zones. Note that this only occurs if restore defaults is performed on the unit AFTER the firmware update.
  • Various improvements and corrections.


Changes in KPC-N v7.1 (03-09-2015)

  • IMPROVEMENT: added support for selecting remote sources. Known issues:
    • If zones are linked across multiple mini4 amplifiers then all the zones in the group will use the same source if the applicable remote source is configured. This means that some zones will be using a local source and some will be using a remote source. This behaviour is currently not expected by the KPC and the incorrect source selection may be indicated.
    • The Media Player applet does not currently control remote media player sources.


Changes in AX800-X firmware v5.1.2 (26-08-2015)

  • CORRECTION (regression in v5.1): TCP (network) processing could lock up the amplifier in certain circumstances.
  • CORRECTION: media player is now stopped if pause is not supported (e.g. for Internet radio or Pandora) when the only zone using the source is turned off or selects another source. This is now also done if a preset selection stops the media player from being used.


Changes in AX800-X firmware v5.1.1 (06-08-2015)

  • CORRECTION (regression in v5.1): presets saved by firmware v5.1 could not be loaded, however preset settings saved by earlier firmware versions could be loaded.
  • Various corrections and improvements in the web application.


Changes in v3.0.1 (R4D/R1D) / v4.0.1 (R4C) (28-07-2015)

  • CORRECTION (regression in v3.0): RS232 ports were not configured (baud rate, etc) if a mobile app simultaneously opened multiple connections to the port. This happens if multiple instances of the same type of applet are present on a page.


Changes in ADP v4.0 (09-07-2015)

  • IMPROVEMENT: uploading can now be performed over the network. General information:
    • Supported devices: KPC-N, R1D/R4D/R4C, Mini4 amplifier. (The firmware on the KPC-N and R1D/R4D/R4C devices must be first updated via USB with the included firmware.)
    • There are more menu options for uploading devices:
      • "Upload selected device (USB)" - this is the original upload function via USB. Nothing obvious has changed here except that it no longer applies to the mobile app. This can be used for the first upload to a device, updating the programming or overwriting with something else. If the device only supports USB uploads then this is the only option available.
      • "Upload selected device with serial number" - this uploads a device in the project to a device on the network using the last (right most) 5 digits of its serial number. Like with the USB upload, this can be used for the first upload to a device, updating the programming or overwriting with something else. The device must be accessible on the same network as the PC.
      • "Update selected device" - this updates the programming of the selected device in the project over the network. The device must have already been uploaded to using one of the above 2 functions otherwise it will not be found and the update will not proceed. This is the upload option used for programming the mobile app.
      • "Update all devices" and "Update changed devices" - this updates the programming of all devices or the bold devices in the project respectively. These functions will update multiple devices simultaneously, provided the "Update selected device" option is available.
      • "Scale and upload" - for scaling mobile app designs when uploading. This allows a reasonably generic design to be uploaded to different devices with different resolutions without it being changed each time.
    • Restrictions:
      • Devices cannot be simply programmed when sitting on the network since they need to be "targeted" somehow. Also we have used encryption in the upload bundles so that the devices will not blindly accept an upload from anyone and anywhere since this is a potential security risk. So, the first upload is either done by USB or by using the device's serial number. The idea is that USB requires physical access and ensures that the person doing the upload has the right to do so and the serial number is only likely to be known by the owner/installer and it is unique enough to enable the device to be targeted on the network if a particular type of device, such as the KPC-N, is installed multiple times.
      • Except for the mobile app, each device in the project must not be implemented by more than one physical device on the network (e.g. one KPC in the project must not be uploaded to several physical KPCs). Each device in the project must be implemented by exactly one physical device, no more, no less.
    • Added a new KPC applet that displays any available updates. This applet is included in the "Darkness", "Cosmos" and "Brushed Aluminium" templates and is activated by tapping the corners of the display in a clockwise fashion starting with the top left corner (see the "system action" setting in the KPC settings). The applet can update the firmware of the host KPC-N or any other KPC-N on the network.
  • IMPROVEMENT: Added support for the new AX-Mini4.
  • IMPROVEMENT: The diagnostics log can now be accessed by USB or a network connection. From the main menu the log can be opened for a network address (either IP address or network name), however in this mode the log does not provide any device specific features like the comms logging options for the R1/R4. From the project's context menu (right click a device in the project tree), the log for a specific device can be opened, if it has already been uploaded to.
  • CHANGE: The "AMC window" used in the amplifier designer now uses a network connection instead of a USB connection. The amplifier in the project must be uploaded to the physical amplifier and it must be accessible on the network. Also there is now a menu option in the "AMC window" for accessing the amplifier's event log via the window's network connection. This is in addition to the event log option in the main menu which uses a USB connection.
  • IMPROVEMENT: The mobile app media player applet has new features for the media player upgrades.


Changes in Mini4 v1.1 (09-07-2015)

  • IMPROVEMENT: Presets are now implemented. Same functionality as on AX400/AX800 except no sounds and page inputs.
  • IMPROVEMENT: Digital audio out 1 and 2 now output whatever is playing in zone 1 and zone 2.
  • CHANGE: source names on amp no longer overwrite the names used on other amplifiers.


Changes in v3.0 (R4D/R1D) / v4.0 (R4C) (09-07-2015)

  • IMPROVEMENT: supports uploads over network from ADP.
  • IMPROVEMENT: can install future firmware updates by downloading them from the web.
  • IMPROVEMENT: added network access to diagnostic log.
  • CORRECTION: fixed problem that frequently caused timeout errors when uploading.
  • Unit ID now logged in the diagnostic log at start up. This ID is used for uploading new projects over the network.
  • CHANGE: IR communications devices has been modified. All R4C/R4D/R1D devices and all KPCs must be updated to the latest firmware.


Changes in KPC-N v7.0 (09-07-2015)

  • IMPROVEMENT: added control of Axium amplifiers over the network without needing an R1/R4. Requires the use of the AX400-X/AX800-X firmware on the amplifier(s).
  • IMPROVEMENT: can now send IR over the network to a port on an amplifier. In ADP an IR device is attached to an amplifier IR port and commands are dragged from the IR device to the KPC.
  • IMPROVEMENT: supports uploads over network from ADP.
  • IMPROVEMENT: can install future firmware updates by downloading them from the web.
  • IMPROVEMENT: added network access to diagnostic log.
  • Unit ID now shown on display at start up. This ID is used for uploading new projects over the network.
  • CHANGE: IR communications between devices has been modified. All KPCs and all R4C/R4D/R1D devices must be updated to the latest firmware.


Changes in AX800-X firmware v5.1 (06-07-2015)

  • Upgrades to Ethernet and TCP/IP functionality to better handle adverse network environments and improve user experience when playing from TuneIn and Pandora.
  • Change: removed preset macro functionality. This was a legacy feature that used keypads to send IR commands and was meant to have been removed in v5.0. It does not affect the preset events and standard macro functionality.


New AX400-X firmware v5.0.1 (26-05-2015)

  • The expansion bus ports on the back panel are no longer used. Instead the communications and IR transferred between amplifiers in the Axium amp stack is done over the network.


New AX800-X firmware v5.0 (09-04-2015)

  • Extensive upgrades to the media player:
    • Added TuneIn.
    • Added UPnP (also known as DLNA) to the media source. This provides "play from my device" functionality from the Axium mobile app.
    • Added Pandora. For the best experience we recommend using a paid "Pandora One" account.
    • Shuffle now available for network shares and USB.
    • Now possible to navigate within a network share during playback.
  • Front panel GUI design upgraded.
  • The expansion bus ports on the back panel are no longer used. Instead the communications and IR transferred between amplifiers in the Axium amp stack is done over the network.
  • Extends KPC Ethernet capabilities without needing an R1/R4.
  • Direct amplifier control over Ethernet without having to use the slower keypad port.
  • IR commands over Ethernet directed to amplifier ports.
  • Removed KNX support and reduced the front panel GUI functionality. This was necessary for the media player upgrades.


Changes in AX400/AX800 Firmware v4.5 (27-08-2014)

  • CORRECTION: after loading the zone page in the web interface some browsers would experience problems loading if no amplifier configuration was uploaded from ADP. This problem was introduced in 4.3.
  • IMPROVEMENT: NetBIOS name resolution (used by media player) can now handle responses containing multiple IP addresses and properly reject addresses from inappropriate subnets.
  • IMPROVEMENT: web application now shows track time in media player. Added workaround for Chrome bug in listbox control causing playback to restart when control was scrolled up or down.
  • IMPROVEMENT: updated mp3 decoder firmware.
