-
Stereo left, right and sub channel
-
Signal, clip and protect indicators
-
Precision front panel input attenuators
-
Channel inserts for processing
-
Adjustable left and right channel crossover frequencies 70Hz-120Hz; sub channel band limited 35Hz-120Hz
-
Switchable high pass filter - low frequency roll-off to prevent transformer saturation in distributed systems
-
Ground lift switch
-
Input overload limiter - automatically reduces channel gain when steady or excessive clipping is detected
-
Output overload protection - automatically reduces channel gain when the amplifier senses mismatched loads
-
Soft startup protection - gradually increases amplifier gain after the amplifier is turned on
-
Thermal overload protection - activates when excessive heatsink or power transformer temperatures are detected
-
Short circuit protection - attenuates the signal and disconnects the load
-
DC voltage offset protection - disconnects output instantly to minimise the risk of speaker damage
