By default, all inputs are enabled. The user just plugs 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.
External mixer
When using an external mixer, it is very important that this is a fixed mixer; automatic, smart and other types of
adaptive mixers will cause malfunction of the echo canceller.
Audio input 5 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.
