10. Audio Utilities
10.1
DMS Metering & Loopbacks
All systems provide DMS elements which can be assigned to a VisTool display for metering or to create audio
loopbacks to feed signals back into other parts of the system.
Mono DMS may be linked to operate in stereo or surround. Each DMS channel is equipped with silence detect
logic.
sapphire compact and Nova29 support 64 DMS; sapphire MK2 and POWER CORE supports 256 DMS
presented in 4 groups of 64.
Additionally Nova29 supports 256 internal loopbacks without silence detect and Vistool metering, presented in 4
groups of 64.
crystal systems also support DMS and Loopbacks, but these operate slightly differently and are accessed
from the "System -> Definition -> Parameter = DMS" branch of the 'Tree Definition'.
To access the parameters:
1.
Select a DMS entry from either the "Audio Input" or "Audio Out Only" branches of the 'Tree Definition'.
2.
Then select the menu tabs to configure the DMS Input and Loopback/Silence parameters.
The same parameters can be accessed by double-clicking on DMS in
parameters can also be edited in list form from the "Command -> Inputs" window.

Note that the audio feeding a DMS may also be configured in reverse - for example, the
DMS may be assigned as the audio input to another configuration element. In this case,
the default audio is overridden.
Define the color for each DMS channel. The color is used for PPM bars in VisTool.
