What to do if there is no sound from my Sony UTX-B03?
- J
  Jasmine Webb MDAug 15, 2025
  If your Sony Microphone isn't producing any sound, ensure that both the transmitter and tuner are set to the same channel. Also, verify that the transmitter is powered on and not muted. The distance between the transmitter and tuner might need to be reduced, or you may need to switch from line level input to microphone input. Finally, check that the compander mode setting is the same on both devices.

Why is there sound interruption or noise in my Sony UTX-B03 Microphone?
- T
  Tina ShafferAug 19, 2025
  If you are experiencing sound interruption or noise with your Sony Microphone, make sure the channel setting is the same on both the transmitter and the tuner. Avoid using the same channel for multiple transmitters. Ensure transmitters are set to channels within the same channel group and use channels separated by at least two channels (250 kHz).

Why do the batteries become drained quickly in my Sony UTX-B03?
- S
  Sandra SmithAug 22, 2025
  If your Sony Microphone's batteries are draining quickly, try replacing them with new ones. Using alkaline batteries instead of manganese batteries can also help, as alkaline batteries last more than twice as long. Keep in mind that cold conditions can also cause batteries to drain faster.

Why is the sound weak on my Sony UTX-B03?
- K
  kyle58Aug 26, 2025
  If the sound from your Sony Microphone is weak, the attenuation level on the transmitter may be too high, so set it to an appropriate level. Also, check the volume on your amplifier or mixer and adjust it as needed. Make sure the transmitter is set to microphone input instead of line level input. Finally, ensure that the compander mode setting is the same on both the transmitter and tuner.

Why is the sound distorted on my Sony UTX-B03 Microphone?
- S
  Sarah JacobsAug 28, 2025
  If the sound from your Sony Microphone is distorted, the attenuation level on the transmitter might be too low or set to 0; adjust it to eliminate distortion. Ensure that the channel setting is the same on both the transmitter and the tuner. If you're using headphones, make sure they have a stereo mini jack instead of a monaural one.

  Amanda KhanAug 31, 2025
  If your Sony Microphone unit does not turn on, make sure the batteries are inserted with the correct polarity. Replace the batteries if they are low. Clean the battery terminals with a cotton swab if they are dirty. Ensure batteries are inserted if the power source is set to 'BATT ONLY', or change the power source setting.

What to do if the transmitter channel cannot be set with infrared transmission on my Sony UTX-B03 Microphone?
- P
  Patrick MillerSep 4, 2025
  If your Sony Microphone's transmitter channel cannot be set with infrared transmission, try reducing the distance between the infrared receptor on the transmitter and the infrared transmission port on the tuner to within about 20 cm (8 in.). Also, minimize interference from other infrared devices or direct sunlight by placing the transmitter and tuner as close as possible.

Why does the RF indicator light up when the transmitter is off on my Sony Microphone?
- A
  Angel DouglasSep 8, 2025
  If the RF indicator on your Sony Microphone tuner lights up even when the transmitter is off, it may be receiving jamming radio waves. Try setting the tuner to a channel where the RF indicator does not light up. Alternatively, use the Clear Channel Scan function to switch to a channel without interference.
