PL 1U Series User Manual
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 CHA input (and CH B if in stereo mode), gradually increase the CHA and CHB
volume controls (only CHA will have an effect in Bridge mode). 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 speaker
