Why are my Electro-Voice ZxA1-90 Speakers buzzing?
- E
  elizabethblackAug 22, 2025
  If your Electro-Voice speakers are producing constant noise like buzzing, hissing, or humming, there are several potential causes: * **Defective Source or Electronic Device:** If the noise persists when no program material is playing, the issue likely originates in the electronics signal chain. Evaluate each component to isolate the problem. * **Poor System Grounding or Ground Loop:** Check and correct the system grounding as required. * **Incorrect Gain Structure:** Verify that the level controls of the source are properly structured. Ensure that microphone cables are plugged into the MIC IN and line-level cables are plugged into LINE IN.

What to do if Electro-Voice Speakers sound distorted and LIMIT LED is on?
- C
  Carlos HansenAug 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 ZxA1-90 Speakers?
- K
  Katherine KentAug 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.

  ashleyharrisAug 28, 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 ZxA1-90 sound distorted when LIMIT LED is off?
- W
  wolfecindyAug 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 Speakers?
- R
  rharrisAug 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.

  Thomas TaylorSep 3, 2025
  If you are experiencing poor low-frequency response with your Electro-Voice ZxA1-Sub, the polarity might be incorrect. Set the NORMAL/REVERSE POLARITY switch to the opposite position.

Why is my Electro-Voice Speakers sound distorted and the LIMIT LED is constantly on?
- T
  Tony SmithSep 5, 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 an excessive input level. To resolve this, reduce the MASTER level or loudspeaker level knobs to prevent limiting. Alternatively, a line-level source might be incorrectly plugged into the MIC IN. Ensure that you plug the line-level source into the LINE IN.

  Isaiah KruegerSep 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.
