The input channel has 2 possible balanced inputs, use one of these inputs to connect a microphone or a line-level
source. If you use an input make sure that the 'mic/line' switch is in the correct position.
Note
If you want to use the priority feature, you must use a microphone or line-level source with a priority contact
on pin 4 and 5 of the 5-pole DIN plug.
