The ITU BS.1770 Input meters indicate the level of the unprocessed source audio coming into
Omnia.9withfloatingpeakindicatorsaboveeachbar.
The AGC meter window shows the levels and action of the Input AGC and the Wideband AGC1
compressors. It also shows the level of the Wideband AGC2 section when it is enabled and
positionedbeforethemultibandsection.
