  If your Current Audio Amplifier isn't producing sound, several factors could be at play. Ensure the unit is plugged into a working, unswitched AC power outlet. Verify all audio cables are securely connected to the correct inputs, and consider replacing them if necessary. If you're using a matrix switcher, confirm it's programmed to send a signal to your input, and check the audio format on your DVD player. Also, make sure the Master Power switch on the rear of the amplifier is set to 'ON' and that the front power switch is toggled to show a BLUE light. Check if a 12 Volt Trigger is applied.

  John ArmstrongSep 13, 2025
  If your Current Audio Amplifier hums when the receiver or source is off, the level might be set too high. Try turning down the rear Level or Global level. The issue might also be due to the Cable TV ground not being the same as the earth ground; in this case, insert an in-line ground isolator. It could also be a ground loop, try to common all grounds, isolate AC ground.
