Why is my Shure UHF WIRELESS Microphone system noisy?
- C
  Charles RamosJul 31, 2025
  If your Shure Microphone system's received signal is noisy, first, check the transmitter's battery and replace it if the power is low. Then, eliminate any nearby RF interference sources, such as lighting. If you're using an instrument, ensure it's properly connected with a Shure WA302 adapter. Also, verify that two transmitters aren't operating on the same frequency. If the signal is weak, reposition the antennas closer to the transmitter and adjust the receiver squelch control.

  If your Shure Microphone system has no receiver sound but the RF and Audio Level meter LEDs are glowing, increase the receiver audio output level. Check the connection between the receiver and the microphone mixer. Speak into the microphone and watch the receiver audio level LEDs. If they light up, the issue lies elsewhere in the sound system.

How to fix momentary loss of sound on Shure Microphone system?
- A
  Anthony MorenoAug 12, 2025
  If you are experiencing momentary sound loss with your Shure Microphone system as the transmitter moves, try repositioning the receiver and perform a walkthrough test, observing the RF level or Diversity signal indicators. If drop-outs persist, identify these 'dead spots' and avoid them during the performance. You may also decrease the squelch control setting, though this might slightly increase noise in those dead spots. Consider moving antennas to a remote location using a UA830 kit.

  Julie JohnsonAug 18, 2025
  If your Shure Microphone system has no sound and the receiver RF light(s) and AUDIO LEDs are not glowing, ensure that the power switches on both the transmitter and receiver are turned on. Check the transmitter's Power/Battery Fuel Gauge and replace the battery if needed. Verify that the transmitter and receiver frequency Group/Channel settings are identical. Also, check the receiver squelch setting and antenna connections. Ensure at least one antenna is within the transmitter's line of sight. Reduce the distance between the transmitter and receiver if necessary.

What to do if Shure UHF WIRELESS has noise from receiver with transmitter off?
- W
  Wayne HumphreyAug 25, 2025
  If your Shure Microphone system is producing noise from the receiver when the transmitter is off, try adjusting the receiver squelch control. Eliminate any local RF interference sources, such as lighting equipment. You might also try using another frequency or repositioning the receiver or antennas.
