  If the power LED on your Bose Amplifier is green but you're not hearing any sound, try these steps: First, ensure the volume control on your instrument is turned up. Next, check that the Trim level control on the power stand is also turned up. Confirm that your instrument is correctly plugged into the Analog Input jack. Try using a different cable to connect your instrument to the power stand. Finally, test your instrument with a different amplifier to verify it's working correctly.

  If your instrument or audio source sounds distorted through the Bose Amplifier, ensure the Signal/Clip LED is not constantly red. If it is, lower the trim level. You can also try using a different source or instrument to see if the issue persists. Alternatively, test your current source or instrument with another power stand to identify the problem.

  If your Bose Amplifier is causing the house circuit breaker to trip, consider these solutions: If you have multiple power stands plugged into the same AC circuit, try staggering their turn-on times. If you're using more than three power stands on a single 15 amp circuit, move some of the systems to another AC circuit.

  To reduce microphone feedback with your Bose Amplifier, try the following: Orient the microphone so it does not point directly at the L1 system. Try using a different microphone. Experiment with different positions for the loudspeaker and/or vocalist on stage. Increase the distance between the loudspeaker and the microphone. If you're using a vocal effects processor, ensure it is not contributing to the feedback.

  If your Bose Amplifier is plugged in and the power switch is on, but the power LED is off, ensure that the AC outlet is providing power. Try plugging in a lamp or another device into the same outlet, or use an AC outlet tester to verify the outlet is working. Also, make sure the power cord is fully inserted into the AC outlet.

  If you're not hearing any bass audio from your B1 or B2 bass module with your Bose Amplifier, check these items: Ensure you are using the 4-wire B1/B2 bass module cable that came with your system. Verify the cable is plugged securely into the Bass Module Out connector. Try using a different 4-wire cable. If possible, test with a different B1/B2 bass module to rule out a faulty module.

  If you are not hearing any mid/high sounds from the L1 top array of your Bose Amplifier, ensure the L1 top array and bottom extension are firmly seated in their connectors. Check that the connections are not bent or broken. You might also try cleaning the contacts on the loudspeaker top and bottom with an electronic contact spray cleaner.

Why is my Bose Amplifier humming or buzzing with nothing plugged in?

  Steve EllisonSep 10, 2025
  If you hear a slight hum or buzz from your Bose Amplifier power stand when nothing is plugged in, use an AC outlet tester to check the AC outlet for reversed or open (hot, neutral, and/or ground) contacts. If you are using an extension cord, test the extension cord as well.
