Sony Wireless Mic (Transmitter) UTX-B1

Transmitter and Receiver of Sony Wireless Mic set stored identically and used very infrequently (non-professional). Error Message "no tone" received. Repairer disassembled both to discover circuit board of transmitter with corrosion. Receiver shows no evidence of environmental degradation. Both stored very securely (pelican case) and neither been out of possession or eyesight of owner. Transmitter has never been "dropped in a beverage" or "immersed in the pool". Any explanation proferred as to why one shows deterioration and the other does not? Any history of factory induced production quality variability?

Sounds like some type of manufacturer's flux problem. As an ex-Sony pro dealer we saw something like this years ago. You might want to contact Sony support (industrial or broadcast, not consumer) and see if there is a technical bulletin out on this problem.

Intermittent LOUD shorting sound

I would prefer to hear it to be sure which one it is, but the four biggest causes of noise in a wireless system are: 1) Something hitting the mic (check to make sure the mic is free of clothing, other people, faces, etc.) 2) If the mic is a lavalier or in some way has a cable that plugs into the transmitter, something pulling on it could create a loud noise. Check to make sure it's in snug. 3) RF Interference with another mic or some other interference source. Try changing the frequency. 4) Something blocking the signal between the transmitter antenna and the receiver antenna. This is most likely to happen with a lavalier in someone's pocket or under clothing, and/or if the transmitter is far away from the receiver. The SLX series is okay for what it is, but part of why it's on the cheaper side is because of its limited distance. Unfortunately the only ways to alleviate this are to a) Reduce the distance, b) get a stronger wireless system, c) move the transmitter somewhere that the antenna is free, and d) invest in True Diversity antennae for the receiver.

I have the AKG wms 40 dual mini mic set with two wireless mics. When mic on ch 2 is in the off position, I get lots of static. Works perfectly fine when on. What do you think is the issue?

Channel 2 mic's receiver needs the Squelch adjusted. The squelch control mutes the receiver so that when the transmitter stops transmitting, erroneous noises are not picked up and amplified.

Do you carry instruction manuals for the Sony (UTX-B1) and the (URX-P1) wireless mic system doesn't "carry" any manuals, but you can download the one that you're looking for here:,%20UWP-C2,%20UWP-S1,%20UWP-S2,%20UWP-X1,%20UWP-X2.pdf

Appreciate the direct "Ask Me".

The Sony PD170 is not an everyday equipment, nonetheless, I will assume that on the Sony DSR PD170:
  • the Samson UHF M32 receiver is plugged to Audio 1;
  • boom mic is plugged to Audio 2; (or vice versa) and
  • Both Audio 1 & 2 are using the XLR connectors.
Assuming that your boom mic is a conventional dynamic, on the Audio Control Panel, pls set:
  • INPUT 1 -
  • +48 OFF
  • INPUT 2 -
  • +48 OFF
This is of course assuming that both the boom mic and the output of the Samson UHF M32 receiver are set to MIC level. In some instances the Samson UHF M32 receiver requires a LINE setting. The only time the +48 is set to ON is when the mic that is used/plug in requires phantom power such as condenser types. If the mic or the Samson UHF M32 receiver requires power then this should be switched ON otherwise, there will be no audio coming in. Though most M32 uses a 9 volts battery.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

1- Does built-in mic work?
2- Connect direct mic and check sound instead of wireless mic and confirm camera audio circuit.
3- It is Sony professional camera and this should be repaired by Sony qualified technician as you stated that your job depends on it so don't take risk. Attempt of repair by unqualified person is not advised.
Hope this info will help you.

Not transmitting through both speakers properly

The UTX-B1 input is not a stereo jack, and the receiver output is also not a stereo jack. Only the receiver Headphone/Monitor jack is stereo.

Not sure if you are sending stereo signals from or to the camcorder. But you can try mono-to-stereo adapter.

Hope it helps!
