Audio Levels

The Audio Levels screen is used for these functions:
•
Set channel levels. Turn on the pink noise on any single channel to check and adjust the level.
With Master Volume control set to -15dB the output on each speaker should be 85dBC when using
an SPL meter.
•
Check channel phase. To do this, enable pink noise on more than one channel and check the
difference in sound level with an SPL meter or RTA.
•
General testing or troubleshooting. The installer may diagnose a problem by muting selected
channels while playing content, or playing pink noise on selected channels.
