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.

Mic1, Mic2 and Mic3 are intended for electret type microphones. The microphone inputs are
balanced with 24V phantom power.

Audio4 is intended for connection to an external microphone amplifier or an external fixed mixer.

Audio5 is intended for connection to external playback devices or to telephone add-on hybrids.

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.

Audio6 is intended for connection to a VCR. It can also be connected to other 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. If ‘Auto’ is
selected, the audio from the VCR will only be heard when VCR is selected as videosource.
