Audio Inputs

By default, all inputs are enabled. Just plug in an audio source and it is active. Audio inputs that are On will
automatically be mixed. Select Off to prevent audio/noise from unused inputs or if you want to disable a specific
input. The activated audio sources are stored on presets.

Mic 1 and 2 are intended for electret type microphones. The microphone inputs are balanced with 11V phantom
power.

Audio input 3 is intended for connection to external playback devices.

As there is no acoustic echo canceller on this input it should not be connected to any microphones. The audio
entering this input will be heard from the local speaker.
