Auto-Mix
– Engages the automatic microphone mixer.
The MP-M auto-mixer is a gain-sharing design and may be used on any or all of the Mic/Line input channels. It works by comparing the signals
from the input channels and applying attenuation (level reduction). In operation, the auto-mixer senses which channels are being spoken into
and allocates gain to the active channels while reducing gain of the inactive channels.
