When in TALKOVER mode, set the:
DEPTH [%]
– to determine the decrease of the audio level during
microphone 1 takeover (press + to further decrease the talkover audio
output level; press
– to lessen the talkover output audio decrease level)
TRIGGER
– to determine the microphone threshold level that triggers the
audio output-level decrease.
ATTACK TIME
– to set the transition time of the audio level reduction after
the signal rises above the threshold level
HOLD TIME
– to define the time period talkover remains active although the
signal falls below the threshold level (for a short period of time)
RELEASE TIME
– to define the transition time for the audio level to return
from its reduced level to its normal level after the Hold Time period
MIC GAIN BOOST

NOISE MUTE
Set to ON or OFF.
ON: Unit enables the audio output only after validating that there is audio
present on the input. (Note that the unit takes 1
– 2 seconds to detect the
presence of audio, so there is a delay before the audio is heard after
switching to a new input).
OFF: The unit does not check the validity of the audio. Audio is always
enabled and there is no delay before the audio is heard after switching
inputs.
