  If your ProSound Amplifier's power LED is on but there's no sound, consider these possibilities: * The input signal might be missing or too weak. Ensure the input is properly connected, and the VU meters display an adequate signal. * The level controls could be set too low. Try increasing them. * The speakers might be faulty or not properly connected. Verify the integrity of your speakers and their connections.

Why is my ProSound Amplifier humming or buzzing?
- T
  Tracy BowenAug 1, 2025
  If you're hearing hum or buzz from your ProSound Amplifier, it could be due to: * Noise from the AC supply entering the signal path. Use high-quality, shielded signal cables, keeping them separate from AC power cables and other AC-powered devices. * An earth problem. Use a mains tester to confirm the AC outlet has a good earth. Where possible, power connected equipment, like the mixer and amp, from the same AC outlet.

  If the sound from your ProSound Amplifier cuts out or is intermittent, it may be due to damaged or poor-quality cables or connectors, connectors not properly inserted, or the amp overheating.
