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 1,2 and 3 are intended for electret type microphones. The microphone inputs are balanced with 24V phantom
power.

Audio input 4 is intended for connection to an external microphone amplifier or an external fixed mixer.
