OPERATION
When all connections to the amplifier are made, turn all rotary controls down and switch on the power and the power button LED
will illuminate. Turn BASS and TREBLE controls to the 12 o'clock position (pointing straight up) and turn MASTER rotary control
up part way for testing.
•
Ensure a signal is being fed to one of the line inputs and gradually increase the volume control for that channel until the
output is heard through the speakers. Turn up the MASTER to the maximum required volume level and reduce the channel
volume control if necessary.
•
Note: The initial test can be made using the built-in USB/SD audio player. The output of the amplifier is represented on the
level meter LEDs. Anything longer than a short flash of this Clip LED may be indicating distortion or clipping of the output
signal and the MASTER should be turned down.
