    10 SETUP: MODE SWITCHES: CLIP LIMITER AND LOW FREQUENCY FIL TERS The CX168 amplifier has separate clip limiters for each of the 8 channels. These clip limiters respond only to actual amplifier clipping. Amplifier clipping generates internal error signals which cause the clip limiter to quickly reduce gain and minimize the overdrive. T o preserve as ...
