Microphone/Line Inputs 1,2
This section describes the installer configuration of the microphone inputs 1 and
2. For each input you can select an attenuator pad, phantom power, lo-cut filter,
adjust equalisation and configure the routing to the outputs. If microphones are
not required you can still use these inputs for additional mono line sources.
To configure the unit switch off power, remove the top cover and adjust the links
and trimmers as shown. Power may be applied for setting up the trimmers.
Avoid the power supply components shown greyed out on the diagram.
