Sony UWP-D16 Mic Transmitter Difficulties

Hi guys,

New to the forum. Have just started filming an outdoors TV show here in New Zealand and was put on to forum by a few people within the filming community.

I have a couple of questions re some of the audio gear we are having difficulties with.

We are using two of the Sony UWP-D16 transmitters with lavalier microphones attached running through the partnering receiver units attached to our Sony PWW-X70 camera through the two input jacks.

Both of the units were working great together, but as of recent one of the transmitting units has been playing up. When you turn the transmitting unit on the sound is normal and clear for variably 5-15 seconds before the unit light starts flashing red and all of the sound becomes distorted. When you reset the unit the same thing continues to occur.

I am new to the industry and am just learning the processes but I have taken into account the following to try and fix the error without success:

- ensuring the channel settings from the transmitter and receiver are the same.
- Inputs are set to the correct line settings (mic +48 etc), in this case set to mic.
- Attenuator and outputs levels set accordingly (have done multiple tests and in this case ATT level of -12 on the transmitter with OP level at +3 on the receiver which seems the best for quality, while creating a sound DB average peaking between -12 and -6 which is what we want to achieve.
- The compander mode on the transmitter is the same on the receiver.

Anyone had these problems with these units or know of a way to assist? Otherwise I'll head back to the manufacturers and probably end up sending the units back.

Thanks guys,

Sam
 
Its a battery / s going flat.....
These units seem to be quite temperamental to low battery level.
If you can get away with it run the transmitter on the 'low' RF power setting for better battery life.
I have also found that even fresh batteries left in the units for a couple of weeks (but not used) seem to very low when you turn them back on.

Alkaline or lithiums are a must, standard carbon AA batteries would be a waste of time / money.
 
I just double checked, but the batteries in the receiving unit are lithium AA which are showing full battery on the level.

So i don't think its the batteries causing this error in this case.

Anyone else have any other suggestions?

Thanks
 
Urgh my mistake sorry, I meant the transmitter. Changed it to a low RF setting like you said which seems to have helped.

Thanks again for you help
