Problems with Sony WRR/WRT-805 wireless
I have a couple of Sony WRT-805 transmitters, both with Sony ECM-77 mics which I use with Sony WRR-805 receivers. Recently, I was doing a job and experienced a number of "dropouts" on certain words, particularly "buts" and "ands". They are not the usual distorted pops that you get if you record sound without a pop shield - the signal simply drops (almost as though a compressor has kicked in) and returns on the next word. If anyone has the time to listen, I can e-mail an MP3 sample of the problem.

This happened probably 20-30 times in a shoot lasting 6 hours - the mic was placed facing downwards (away from the presenter's mouth). I ended up replacing the radio system with a wired ECM-77 (mic placed identically for continuity) and the problem went away. I can only assume that the sound level at the mic was overloading the transmitter input...

Subsequent testing on both wireless systems revealed that the problem exisits on both, so i can't imagine it's a fault. I tried changing attenuation settings, phase settings etc.

My problem is that I can't always use a wired mic (that's why I've got the radios!) and I can't think how to stop the pops. The Sony 805 appears to have quite a good name, so I can't imagine it's a "feature".

The bottom line is that I'll have to change mic system unless I can solve the problem, so if anyone can help, it would be appreciated! If not, advice on new radio mics would be great!

Sorry for the long post!

mute switch
We had the same problem we turned off the muting switch on the receiver and it was fixed.
