Behringer 1002B Mixer question

[y2kindyz]

Hello all,
I am using a XENYX 1002B Mixer for my at home Kareoke with a set of GTD Audio G-788 wireless mics. I made up some wires with XLR from the wireless receiver and 1/4" to the channel mono on the mixer. I have noticed that the mics have to be turned up past 0 in order to keep up with the input from the computer.

Is there any advantage to using the XLR to XLR? Is the signal more sensitive on the XLR vs 1/4" line in?

thanks in advance,

Oscar

Depends on whether the output on the wireless unit is mic level output or line level. If line level, then it should be XLR to 1/4" TRS. If you just used TS - it's not balanced.

No spec sheet on their website, just "features" .... which tells you nothing. XLR can be mic level or line level. 1/4" output could be TS unbalanced or TRS balanced. Unfortunately, the cheaper brands often don't give much info....and don't have pictures of the back panel.

Thanks for the reply bruce,

The wireless receiver has two XLR individual outputs and one 1/4" Mixed output.

I just found this:
"Microphone level is generally significantly lower than line level. Depending upon the microphone and the sound pressure level (SPL) injected into the microphone, the level may range from a few microvolts for a whisper, up to
several volts for a microphone in front of a guitar cabinet. Mic level needs amplifying up to line level with a
microphone pre amp (usually built into mixing desks) for use with mixers and PA systems."

Edit: Sent email to confirm signal level on the G-788.

That tells me that I need to run XLR to XLR. I hope it brings up the signal.

Often the outputs will be listed as mic or line. The 1/4" is most certainly line level....but +4 or -10? That's the balanced or unbalanced issue. Check the back of the unit...see if it says anything.

While this is true....it really has no relevance to your issue. What you need to know is what kind of output the wireless receiver puts out.

My bet is the the XLR output is mic level....as most people would use it that way by putting the receiver in line before a mixing board.

Try the XLR to XLR....it will probably be the solution.

Just received a reply from GTD Audio. XLR outputs are mic level. So that explains the low input level into the Mixer. Will be changing 1/4" TRS for XLR.

thanks for all your help,
