F. Clip

This light is in fact rather more sophisticated than a simple clip indicator; it actually measures distortion. This may occur either due to clipping, trying to drive too low an impedance speaker load or any other mechanism that causes the output of the amplifier channel to not be as expected by the monitoring circuit. Note that if the amplifier channel is muted by the microprocessor and a signal is applied, the clip light will come on.

G. Bridge

If this light is on it indicates that the amplifier has been configured for bridge mode operation by the rear panel switch.
