POWER AMPLIFIER OUTPUT PROCESSING/MONITORING
Output short detect* Senses load <1 Ohm for Stereo/Parallel modes; <2 Ohms in Bridged Mono mode. Threshold is adjustable in software
Output open detect* Senses load >60 Ohms. Threshold is adjustable in software.
Output voltage meter Range automatically matches to amplifier model used.
Output current meter Range automatically matches to amplifier model used.
Amp gain* Determines amplifier gain control setting, range automatically matches to amplifier model.
*Signal level must be greater than -32 dB, referenced to maximum output of amplifier
