    What to do if my Electro-Voice Speakers have no sound?

      Daniel FranklinJul 27, 2025
      If your Electro-Voice Speakers have no sound, first check the amplifier by connecting a known working test loudspeaker to its outputs. If there's still no sound, ensure all electronics are on, the signal routing is correct, the source is active, and the volume is turned up. Correct, repair, or replace components as needed. If there is sound from the test loudspeaker, the issue lies in the wiring. Verify you've connected the correct cables to the amplifier. Play something quietly through the amplifier, then connect the test loudspeaker in parallel with the malfunctioning line. If the sound disappears or is very weak, there's likely a short in the line. Use the test loudspeaker to test each connection until you locate and fix the problem, ensuring proper polarity.

    Why do my Electro-Voice EKX-12 have constant buzzing, hissing, or humming noise?

      Constant noise like buzzing, hissing, or humming from your Electro-Voice Speakers can stem from a defective source or other electronic device. If the noise is present even when no program material is playing, evaluate each component to isolate the problem. Most likely there is a break in the signal path. Another potential cause is poor system grounding or a ground loop. In this case, check and correct the system grounding as required.

      If your Electro-Voice Speakers are experiencing intermittent output issues like cracking or distortion, start by checking all connections at the amplifier and loudspeakers. Ensure they are clean and tight. If the problem continues, inspect the wiring as described in the troubleshooting steps for 'No sound'.

    How to fix poor low-frequency response on Electro-Voice Speakers?
    • D
      Dawn WattsAug 18, 2025
      Poor low-frequency response in Electro-Voice Speakers can occur if loudspeakers are wired out-of-polarity. When two loudspeakers are connected out of polarity, the low frequencies will cancel each other acoustically. Carefully check the wire markings or tracers on your loudspeaker wires. Make sure the amplifier (-) terminal is connected to pin 1+ of the NL4 connector and the amplifier (-) terminal is connected to pin 1- of the NL4 connector.
