Hi, I bought recently a Sony HVR-A1E video cam and two sets of Sony UWP-V1/62 wireless mics. When I connect both receivers, one to CH1 and other to CH2, a strange, irritating metallic buzz can be heard.

I have different frequencies for mics. Both mics works perfectly separately. Can anyone give me any help how to get rid of this horrible sound and what is causing the sound? Appreciate all comments and advice.

Thanks,

sample?

Do both work on both channels separately. It could just be the other channel. It could also be florescent lighting. Electrical issues. And other forms of interference. Cordless phones, cell phones, wireless network adapters, and other things. There was a fairly recent re-assignment of wireless frequencies, you might want to check to see if those wireless devices are not on the wrong side of that formula.

Wireless Mics must vacate 700MHz band by June 12, 2010

>> Yes.
I am turning to "electrical issues"; must be the reason.

Many thanks for the PDF, will read it through.
Let u know if the problem was solved.
