Why is my Shure SC signal noisy?

  A noisy signal from your Shure Microphone system can stem from several factors. First, check the battery fuel gauge and replace the battery if the power is low. Strong local sources of interference can also cause noise, so try to identify and remove them if possible. You might also need to reposition the receiver or antennas, or change the system frequency. Ensure that two transmitters aren't operating on the same frequency, and if the signal is weak, move the receiver antennas closer to the transmitter. Adjusting the receiver squelch control and the transmitter audio gain control may also help.

  If your Shure Microphone system has no sound but the RF and Audio LEDs are lit, first turn up the receiver volume control with the transmitter power switch on. Check the connections between the receiver and the microphone mixer. Then, talk into the microphone and observe the receiver audio LEDs. If they illuminate, the problem lies elsewhere in your sound system.

  If your Shure Microphone system has no sound and the RF and Audio LEDs are not lit, ensure that both the transmitter and receiver are turned on. Check the transmitter's battery fuel gauge and replace the battery if necessary. Verify that the receiver power supply is properly plugged into both an AC outlet and the receiver's POWER jack. Make sure the frequency selector switch settings on the transmitter and receiver are identical and not set between channels. Check the receiver squelch setting, and ensure that the receiver antenna connections are secure. Confirm that the transmitter and receiver antennas are in a direct line of sight, free from any reflective obstacles. If needed, reduce the distance between the transmitter and the receiver.

Why does my Shure Microphone system make noise when the transmitter is off?

  If you're experiencing noise from the receiver when the transmitter is off, or a popping sound when the transmitter is turned on or off, the tone key squelch switch may be set to the OFF position. To resolve this, open the door on the receiver to access the controls and return the switch to the ON position. You can also adjust the receiver squelch control. Additionally, check for and remove any strong local sources of interference, if possible. Repositioning the receiver or antennas, or changing the system frequency may also help.
