Ensure that the cooling vents at front and rear (10) are not covered or obstructed in any way with adequate space for airflow through the unit.

Operation

With CH A and CH B volume controls (3, 5) turned fully down (anti-clockwise), switch on the power (1) and the LED POWER indicator will light (4)
Playing the input signal into CH A and CH B inputs (6, 7), gradually increase the CH A and CH B volume controls. The amplified signal should be heard through the speakers and the SIG indicators (4) should respond to the audio output. Increase the volume controls to the required level.
Alongside the SIG indicators are CLIP indicators, which should only light very briefly on the loudest transients or spikes in the audio. If the CLIP LEDs light for more than a fraction of a second at a time, the volume controls should be turned down or input signal will need to be reduced.
Before powering down, turn down the volume controls to avoid loud pops or noises through the speakers.
