Dolby DMA (Amplifier) Firmware Update Thread

[Steve Guttag]

I debated starting this thread as these sorts of products from Dolby don't, often, receive updates (it's an amplifier, after all). However, this update is a bit special and I did beta test it. For Q-SYS information on this update, head over to Q-SYS Corner (hint, the DMA is stable with Q-SYS AES67 transmitters now...if you are careful).

Firmware Release 3.1.0.11

NOTE: You must perform the upgrade to v3.1.0.11 twice for full feature functionality. The first upgrade can be either USB or via Web UI. But the second upgrade MUST be done via Web UI. Otherwise, USB features will not function and the downloadable documents in the “documentation” section of the Web UI will not be accessible.


Dolby Multichannel Amplifier software v3.1.0.11 new features

Dolby Multichannel Amplifier software v3.1.0.11 includes new features.

• Power Standby Mode You can set the amplifier to a low-power mode when it is not in-use for additional power savings.
  • Includes a Schedule Mode option when the DMA is connected to a valid NTP source, can be managed via Web UI or SNMP.
  • Front panel Power Button will turn flashing orange when in Standby Mode and a long press of the button will engage normal operation in a few seconds.
  • ▪ Power button for Standy mode On/Off status has been added to the Web UI.
  • ▪ This icon can also be used to toggle Standby Mode OFF.
  • Selectable profiles for Digital and Analog Inputs
  • User selectable labels for channels in the Web UI. These labels are shown on several pages in the web UI for easier operation of the unit.
  • 16A breaker rating option for the India region
  • Updated Dolby Atmos Connect behaviors intended to improve communication with non-Dolby standard AES67 networks.
  • Log extraction now takes less time.
  • All fan speeds have been optimized, which should result in lower overall noise of the device.
  • Reduced the number of times a password prompt appears in the web client user-control screen when making changes to system settings.
  • Added icons at the top of the UI to indicate status of:
    • Power
    • USB flash drive connected
    • Log extraction in progress
    • Upload in progress
  • SNMP now includes fan status information in addition to alerts.
  • Renamed power supply fuse condition from fault to status.
  • Reordered the web client user-control screen navigation bar.

It should be noted, the whole Power standby feature is done via SNMP as the DMA only communicates (for control) via SNMP. Standby mode just turns off the amplifier modules. The other modules remain on but this still cuts the power way down.

I should point out, a new feature is the ability to label the channels. They didn't apply the labels to the meters but they are there in the routing screen.
