Gain Comparator Limiting. When a signal has waveform peaks that exceed the amps' power-supply rails, waveforms get chopped off, or "clipped." This undesirable distortion most often happens when the amp is turned up too high (too much gain). GCLT senses clipping (or current limiting) & dynamically reduces the gain for a few milliseconds. You can drive the CPX amp to its maximum (and beyond) without hearing audible distortion. Don't settle for less. If you need maximum performance on a tight budget, you owe it to yourself to get your hands on a CPX Series amplifier from Crest Performance.
