MUSIC SOURCE SELECTION
The music source selection can be achieved in two ways. The first is to use
the front panel music source selector switch. The second is to use a remote
selector switch. If a remote selector switch is used the remote switch is
connected to the remote connector on zone 1. The remote source selector
unit will also control the music volume remotely. The remote selector
controls can typically be located up to 100m from the unit.

Connecting a fixed resistor across pins 1 and 3 of the zone 1 output
connector will lock the music source to the particular line source.
REMOTE VOLUME CONTROL
The mixer/ equaliser will work with remote control
volume plates. These override the front panel volume
settings. The connections for the remote volume
control are located on the rear of the unit below the
signal output connections.
Connection of the remote music plate to the rear of the
unit is as shown below.
