How to fix Cerwin-Vega Speakers when there is no sound?
- T
  Tonya Joseph DDSAug 8, 2025
  If your Cerwin-Vega speakers aren't producing any sound, several factors could be at play. First, ensure the loudspeaker is connected to an active AC power source and that the power switch on the back is in the 'ON' position. Also, check that the input and main volume levels aren't set too low; adjust them until you can hear sound. Finally, verify that the audio source is active, its volume isn't too low, and the cable connections are secure. The signal indicator on the back of the loudspeaker can help confirm if an audio signal is present. Microphones requiring phantom power must be used with an external power source.

Why do my Cerwin-Vega Speakers have bad sound?
- R

  If your Cerwin-Vega speakers are producing bad sound, check the equipment settings to ensure they aren't causing distortion. Verify all cable connections are good, clean, and free of damage. Ensure that rattling sounds do not come from the caster wheels (subwoofer only), loudspeaker stands or any furniture or fixtures located near the system. Avoid using an AC power source connected to a light dimmer and avoid routing the audio signal cables along other power cables, transformers and signal cables to prevent interference.

What to do if Cerwin-Vega Speakers have no power?

  Elizabeth ShieldsAug 20, 2025
  If your Cerwin-Vega loudspeaker isn't receiving power, start by confirming it's connected to an active AC power source and that the power switch is in the 'ON' position. Also, ensure that the AC power source voltage isn't too low or too high, as the loudspeaker will protect itself if the voltage is 10% outside its intended range. Finally, inspect the fuse on the rear of the loudspeaker and replace it if necessary, after disconnecting all power connections. Refer to the specifications for fuse information.

How to eliminate ground loop hum in Cerwin-Vega P1800SX?
- I
  ian58Aug 26, 2025
  To address a ground loop 'hum' in your Cerwin-Vega speakers, begin by turning all volume and input levels to the minimum to check if the hum originates from connected audio equipment. If the hum persists, disconnect all audio cable connections; if the hum disappears, a ground loop is likely the issue. Ground lifting the signal cable (using a direct box or coupling transformer) is the safest way to eliminate ground loops. Ensure all audio equipment AC power connections are plugged into the same outlet with a common ground, verifying the outlet can handle the equipment's power needs without overloading. Use a balanced connection to take advantage of the best noise rejection. Also, keep the distance between the AC power source and common ground as short as possible.

Why do my Cerwin-Vega P1800SX Speakers keep shutting down?
- B
  brenda21Aug 31, 2025
  If your Cerwin-Vega loudspeaker is shutting down, avoid placing it near heat sources or in direct sunlight. Also, avoid using an audio source with a clipped or distorted input signal. Check that the limiter indicators aren't always on; if they are, lower the input and volume levels until the limiter indicator turns 'OFF'. This prevents the loudspeaker's self-protection mechanism from activating.
