Sennheiser G2 to Soundboard at DVinfo.net

Brian Maynard · January 21st, 2010, 04:31 PM

Hi everybody.

Sorry for such a simplistic question, I thought I had this handled, but I am having a problem.

I have a set of Sennheiser G2 wireless mics. At a recent event, I plugged the transmitter into an "out" on the soundboard via an XLR cable and the receiver was connected to a camera. The audio sounded "overdriven". Is the "out" powered and is that why I am having the problem? Should I be looking for an "unpowered" connection?

Thanks in advance for any help.

The soundboard "out" is likely line level, about 50 db hotter than mike level. I have used the Senny xlr-transmitter (butt-plug, they call it, sorry) in this situation with the input level adjusted down --iirc it goes to -40db-and that worked passably. If this is something you might do routinely you might look at an xlr in-line attenuator --- Audio Technica makes a nice adjustable one for a reasonable price --- see B&H or Markertek.com...../Battle Vaughan

As Battle Vaughan said, adding a 30-50dB in-line attenuator will work and is the easiest.
Another option is buying or making an input cable using the 'Ring' conductor as hot, on the transmitter cable's 1/8" input plug. (float or tie the 'Tip' to ground/shield)
However... this is only good for -10dB levels, but this is readily available on most mixers.

Battle,
that makes sense. Thank you for taking the time to help. I did some more research on the internet and found even more information based on your suggestions.

I think we have it figured out.

Thanks again for your help.

The input of the G2 transmitter has 3 lines, one for the ground, one for the mic and one for line input. I just don't remember which is the line input, the tip or the center.

The G2 mini-jack has the line input connected ring and sleeve only with the tip not connected (though on the new G3 you have to short tip to sleeve).

There are volts on the tip (mic. i/p) to power a mic.
