Operation
When all connections to the amplifier are made, turn all rotary controls down and switch on the power (11).
The power LED will illuminate.
To check for correct operation of the system, select an input source and output zone for testing.
In the following example, Mic.1 input and Zone 1 output have been selected.
•
Turn the Zone 1 Bass and Treble rotary controls (7, 8) to the vertical (12 o’clock) position
•
Turn up Zone 1 Master volume control (9) part way for testing
•
Make sure that the Zone 1 assign button for Mic.1 channel (14) is pressed in
•
Speak into the microphone connected to the Mic.1 input (36)
•
Gradually turn up the Mic.1 level control (2) whilst checking the LED indicators for Zone 1 (10)
•
The microphone should now be audible through loudspeakers connected to the Zone 1 speaker output.
•
Increase the Zone 1 output level to the maximum required volume for that zone
•
Reduce the Mic/Line level to compensate
The above process can be extended to check all other input channels.
If preferred, the system can be checked using the onboard multi-source audio player.
Full information on the operation of this feature is detailed below.
Repeat the above process for Zone 2 to check output to the speakers from the enabled input channels.
Each zone has Bass and Treble controls to adjust the tonal content.
Bass controls the low frequency content and Treble controls the high frequency content.
The vertical (12 o’clock) position is neutral, rotating to the left is cut and to the right is boost.
Adjust both controls for each zone to give the desired tonal character to the connected speakers.
