Why is my Shure Microphone system signal noisy?

  If your Shure Microphone system receiver's signal is noisy or contains extraneous sounds while the transmitter is on, first check the transmitter's power/battery fuel gauge and replace the battery if the power is low. Then, try removing any local sources of RF interference, such as lighting equipment. If you're using a guitar or another instrument, ensure it's connected to the UC1 with a Shure WA302 adapter cable. It's also possible that two transmitters are operating on the same frequency, so locate and turn one off or change its frequency. Finally, the signal may be too weak, so reposition the antennas closer to the transmitter and adjust the receiver's squelch control.

How to fix a Shure UC4 Microphone system with no sound?

  If your Shure Microphone system has no sound and the receiver RF LED(s) and AUDIO LEDs are not glowing, ensure that both the transmitter and receiver are turned on. Check the transmitter's Power/Battery Fuel Gauge and replace the battery if necessary. Verify that the transmitter and receiver frequency Group/Channel settings are identical. Also, check the receiver's squelch setting and antenna connection(s). Make sure at least one antenna is in the line of sight of the transmitter. If needed, reduce the distance between the transmitter and receiver.

  If you are experiencing a momentary loss of sound as the transmitter is moved around the performing area with your Shure Microphone system, try repositioning the receiver and perform another walkthrough test, observing the RF level or Diversity signal indicators. If audio dropouts persist, mark these dead spots in the performing area and avoid them during the performance. You may also try decreasing the squelch control setting, even though noise in dead spots may increase slightly. Another solution is to move the antennas to a remote location.

  If your Shure Microphone system receiver has no sound, but the RF and AUDIO level meter LEDs are glowing, turn up the receiver audio output Level control. Then, check for a proper connection between the receiver and the microphone mixer. Try talking into the microphone and observe the receiver audio level LEDs. If they glow, the problem is elsewhere in the sound system.
