How to fix hum or buzz in Harman speakers that changes with mixer level?

  monicabrownSep 10, 2025
  If you hear a hum or buzz from your Harman speakers that increases or decreases when the mixer level controls are moved, it could be due to an improper A/C ground or faulty equipment connected to the mixer input, or a faulty cable between the source equipment and mixer. Try disconnecting or muting channels one at a time to isolate the problem. Also, substitute a known-good cable for the suspected faulty cable. Refer to the owner’s manual of the faulty equipment for troubleshooting help.

  If your Harman speaker powers on but doesn't produce any sound, the issue might be with the signal source or the cables. First, check the VU meters on the source mixer. Then, verify that the tape or CD is playing. Use headphones to confirm the instrument is actually sending an audio signal. Also, disconnect and re-seat signal cables, or replace any suspected cable with one that is known to be working.

  If your Harman speaker has no sound, first, check that the speaker is connected to an active AC power source and that the circuit is on. Next, ensure the power is switched on and the power LED is lit. Also, verify that the speaker is not in bypass mode by twisting any knob or pressing the bypass button.

  If your Harman speaker is connected to working AC power but won’t come on, the speaker power cable may be faulty or improperly connected. Try re-seating the power cable at both ends and substitute a known-good power cable.

Why is my Harman speaker signal distorted and very loud?
- N
  Nicole PhelpsAug 28, 2025
  The signal may sound distorted and very loud, with the PEAK light frequently illuminated, because the input signal is too high, pushing the speakers beyond their limit. Try these steps: * Lower the output level from the signal source. * Reduce the level controls on the speaker itself. * Consider using additional VE speakers to distribute the load.

Why is my Harman speaker humming or buzzing?
- B

  A hum or buzz could stem from several factors: * Improper A/C grounding or ground loops may be the cause. Try 'lifting' the audio ground using an XLR/F to XLR/M adapter on one end or re-routing audio cables away from AC power and lighting cables. * An excessively long unbalanced cable run could be the issue. Use the balanced outputs (if available) of your mixer or source equipment or use a DI box to convert your unbalanced equipment output to a balanced output. * Improper system gain structure may also contribute. Reduce the INPUT level controls and increase the output level of your source devices.

  If you hear noise or hiss at the output of your Harman speakers, a noisy source device might be the cause. Disconnect the devices connected to your speaker one at a time. If the noise goes away, the problem is with the source or the connecting cable.

  If you are experiencing hum or buzz from your Harman speakers, it may be due to improper A/C grounding or ground loops, excessively long unbalanced cable runs, or an improper system gain structure. Try these solutions: 1. 'Lift' the audio ground by using an XLR/F to XLR/M adapter on one end. 2. Re-route audio cables away from AC power and lighting cables. 3. Use the balanced outputs (if available) of your mixer or source equipment. 4. Use a “DI” (direct injection) box to convert your unbalanced equipment output to a balanced output. 5. Reduce the INPUT level controls and increase the output level of your source devices.

Why is my Harman speaker signal distorted at moderate volumes?
- L
  lindseymaxwellSep 8, 2025
  If the signal from your Harman speaker sounds distorted even at moderate volumes and the LIMIT light is not lit, the mixer or another source might be overdriven. Consult the owner’s manual for your mixer to adjust controls such as input sensitivity (gain), channel faders, and master faders. Then, review the instructions in the Quick Start section of this guide.

What to do if my Harman speaker has no sound with a microphone connected?
- J
  Jeremiah WilliamsSep 5, 2025
  If you're not getting any sound when connecting a microphone directly to the MIC/LINE input of your Harman speaker, it might be because the microphone requires phantom power, which the VE does not supply. Try using a dynamic microphone, a battery-powered microphone (if possible), or an external phantom power supply for condenser-type microphones.
