- Page 7 When using Bridge mode, the connected enclosure impedance must be 4 or 8 Ohms — never below 4 Ohms. Crest Audio's patented GCL (Gain Comparator Limiting) circuit enables the sound technician to maximize the performance of the amplifier/speaker combination by preventing the power amplifier from running out of headroom (clipping). This limiting system is activated by a unique circuit that senses signal conditions that might overload the amplifier and activates compression (reduces the channel gain) when clipping is imminent.
