Protection Circuitry
GCL (Gain Comparator Limiting)
Monitors input/output gain and reduces signal when distortion or excessive high current conditions occur. Protects loudspeakers from dangerous transients and unexpected level changes. Transparent in operation, yet very effective for
its designed purpose.
Amp monitors internal heat sink temperature and temporarily shuts down during extreme thermal conditions.
DC Triac Crowbar: Prevents amplifier from putting out or receiving
dangerous DC over the speaker lines.
Turn On/Off Muting
Outputs are muted during turn on and turn off to prevent audible pop through speakers.
