  • Feature: (Redundancy) Reflect synchronization to secondary AVB stream in Clock state

  • Fix: 0 dBFS signals immediately following a clipped signal would continue to indicate OVR

  • Feature: Improved user guidance after change of sampling rate while streaming

  • Feature: Faster preset name changes

  • Feature (WebUI/GUI): Better visualization of peak levels when peak levels are activated

  • Feature (WebUI): Improved appearance of truncated labels

  • Feature (WebUI): Change device name using the web interface

  • Feature (WebUI): Show miniature level meters while in routing mode

  • Fix (WebUI): Firmware update will proceed even if browser connection is lost

  • Feature (GUI): Network configuration (IP address) can be performed at the device

  • Feature (GUI): New Identify Screen

  • Fix: Switch off ethernet port LEDs on startup

Changing sampling rates will change the sampling rate of the device but keep existing AVB streams running with wrong stream format and audio payload due to MILAN requirements. It is highly recommended to use an ATDECC controller (Milan Manager® or Hive) to manage routing and sampling rate changes in MILAN environments.

  • several additional fixes and improvements for the web remote

Existing presets will be updated to the new firmware and cannot be used with previous firmware versions. Please back up your existing presets in case there is a need to revert to an earlier firmware.
Firmware 2.1.0 (NOV/04/2020)

  • feature: upload and download presets

  • feature: possibility to rename presets

  • feature: automatic update checks

  • feature: AVB: media locked counter for input streams

  • feature: web: direct link to online manual

  • improved: web: font rendering

  • improved: web: error handling (WebGL)

  • fix: web: memory usage in routing mode

  • fix: web: several graphics issues

  • and additional minor fixes and improvements

Firmware 2.0.0 (18/08/2020)

  • Increased AVB I/O to 128 channels, 8 streams

  • MILAN compatibility

  • Implements new web remote user interface

  • Implements new JSON API for remote control

  • Adds single channel routing across all I/O

Firmware 1.2.4 (13/05/2020)

  • Supports more than 8 listeners per AVB stream

Firmware 1.2.3 (31/01/2020)

  • Fixes a sample-offset in AD conversion

Firmware 1.2.2 (02/07/2019)

  • Added a new fan preset "Off". Fan is only turned on when temperature at analog section rises above 70 deg Celsius. Should only be used when the device is installed with sufficient free space to ensure natural convection.

  • Optimized fan curve for preset "Normal" (formerly "Silent"). Fan is running permanently at lowest speed.

Firmware 1.2.1 (08/04/2019)
