Hi,
Today I´ve finished the work on my wireless system for my fiddle. It consists of a Sennheiser MKE2 Mic installed into the fiddle (soundlab symphonic microphone system) and a Sennheiser BF1083 UHF transmitter fixed under the back of the fiddle with a custom-made holder.
My problem: I even get clipping (caused by an overloaded transmitter-input) when the pad switch at the transmitter is switched to -20dB. That´s because of the high sound pressure inside the instrument. I know that the mic can easily handle this sound pressure (it worked fine without the transmitter).
So I´d like to build a pad between the mic and the transmitter. The problem: It is an unbalanced line that simultaneously carries the 9VDC and the signal (in german called "9V Tonaderspeisung"). Any idea, what I could do?? Perhaps a voltage-divider using two resistors? This will lower the signal, but the supply voltage as well... (At the moment I can measure 6.4 volts with a not very fresh battery... a guy from Sennheiser told me, that the mic will run from 5 to 12VDC)
Thanx & happy new year )
