Name: Choose a name that describes the mix of input connectors.
MixerMode Auto: The microphone with the strongest speaker is active and the others are strongly attenuated.
MixerMode Fixed: The input connector signals are mixed together with equal gains.
MixerMode GainShared: The microphones are given a normalized gain factor relative to the strongest speaker
before being mixed together.
AGC: Automatic Gain Control.
Mute: Mutes the mix of input connectors.
Channels: Set channels to 1 to mix the input connectors into a mono signal. To mix the input connectors into
a stereo signal, set channels to 2.
