Passive Surround circuit diagram

Circuit Notes:

  • This passive surround circuit MUST be connected after power amplifier module.
  • Use full range type of loudspeaker. Do not use woofer or tweeter speakers for rear speakers.
  • Left Front and Right Front can be speaker box contains woofer and tweeter.
  • 5W resistors is a must, 1/4 or 1/2 watt resistor will make it burned.

Loud Speaker Position:
LF : Output > connect to Left Front Speaker
RF : Output > connect to Right Front Speaker
LR : Output > connect to Left Rear Speaker
RR : Output > connect to Right Rear Speaker

surround speaker placement

Switch operations:
1 : Quadrophonic
2 : Surround
3 : Stereo (passive surround deactivated, Rear Speakers disconnected)
