Why do Electro-Voice ZxA1-Sub have acoustic feedback when the microphone input level is amplified?
- M
  Martha Cook MDSep 12, 2025
  Acoustic feedback from your Electro-Voice Speakers when the microphone input level is amplified can occur due to a few reasons. First, there might be an incorrect gain structure; reduce the microphone levels at the mixing console or input source. Second, the microphone position may be too close to the front of the speaker. Set up the speakers so the microphone is behind them to mitigate feedback.

What to do if Electro-Voice ZxA1-Sub sound distorted and LIMIT LED is on?
- J
  Jessica EstradaAug 25, 2025
  If the sound from your Electro-Voice speakers is distorted and the LIMIT LED is constantly on or flashing regularly, it could be due to excessive input level or incorrect input connection. Try these solutions: * Reduce the Master Level or loudspeaker level knobs to prevent limiting. * Ensure that line-level sources are plugged into the LINE IN, not the MIC IN.

How to stop microphone feedback with Electro-Voice Speakers?

  Chad RubioAug 27, 2025
  If your microphone produces acoustic feedback when the input level is amplified through your Electro-Voice speakers, the issue likely stems from incorrect gain structure or microphone placement. Try these solutions: * Reduce the microphone levels at the mixing console or input source. If the microphone is connected directly to the speaker, reduce the MIC LEVEL on the speaker. Positioning the microphone close to the sound source will increase gain-before-feedback. * Whenever possible, set up the speakers so the microphone is behind them. If using the speakers in a monitor position, aim the speaker to the back of the microphone.

What to do if Electro-Voice ZxA1-Sub have crackling sound?
- R
  Regina Frank DDSAug 27, 2025
  If you're experiencing intermittent output, such as crackling or distortion, from your Electro-Voice speakers, a faulty connection is a likely cause. Check all connections at the amplifier and speakers to ensure they are clean and tight. If the problem persists, it may be in the amplifier or wiring. Refer to the troubleshooting steps for 'No Sound'.

Why do Electro-Voice Speakers sound distorted when LIMIT LED is off?

  Tiffany WilsonAug 29, 2025
  If your Electro-Voice speakers are producing distorted sound and the LIMIT LED is not blinking, the source input (mixing console/preamp) might be overdriven. Verify that the level controls of the source are properly structured.

Why is there no sound from the microphone connected to MIC IN on Electro-Voice ZxA1-Sub?
- A
  Anna MoralesAug 31, 2025
  If no sound is produced when a microphone is connected to the MIC IN of your Electro-Voice speakers, the microphone might require phantom power. Use a dynamic microphone that does not require phantom power or, if using a microphone that requires it, use an external phantom power source.

How to troubleshoot no sound from my Electro-Voice Speakers?
- J
  jonesjasonNov 20, 2025
  If your Electro-Voice speakers produce no sound, the issue might stem from the amplifier or the wiring. * **Amplifier Issues:** Connect a working test speaker to the amplifier outputs. If there's still no sound, ensure all electronics are powered on, the signal routing is correct, the source is active, and the volume is adequately adjusted. Correct, repair, or replace components as needed. If the test speaker works, the problem lies in the wiring. * **Wiring Problems:** Verify the correct wire pairs are connected to the amplifier. Play audio at a low level and connect the test speaker in parallel with the malfunctioning line. A significant drop in sound level indicates a short circuit, possibly from damage to the wire. Normal sound level suggests an open wire, like a cut or disconnec...

Why is my Electro-Voice Speakers sound distorted even though the LIMIT LED is not blinking?
- K
  Kevin MurphySep 10, 2025
  If your Electro-Voice Speakers' sound is distorted but the LIMIT LED is not blinking, the source input (mixing console/preamp) might be overdriven. Verify the level controls of the source are properly structured to resolve this issue.

What to do if my Electro-Voice Speakers produce constant noise?
- X
  xbrowningSep 6, 2025
  If your Electro-Voice Speakers are producing constant noise such as buzzing, hissing, or humming, the issue could stem from several causes. It might be a defective source or another electronic device. If noise is present even without program material playing, evaluate each component to isolate the problem. Poor system grounding or a ground loop could also be the cause; check and correct the system grounding as needed. Finally, verify that the level controls of the source are properly structured, as an incorrect gain structure can also lead to constant noise.
