    Either pair of amplifiers can be bridged to allow several channel and power output capabilities. It can be configured into three power packages as follows:
  • Four 35-watt amplifiers. (4 Mono speaker outputs or 2 Stereo Zone outputs)
  • One 70 and two 35-watt amplifiers. (1 Mono 70 Watt and 1 Stereo 35-watt output)
  • Two 70-watt amplifiers. (single Zone Stereo 70-watt output)

    Status LED Indicators
