"Hi,

Bit confused here. You're stating a wireless microphone. Have you got some sort of wireless equipment connected to either the Behringer Eurolive B212D XLR input or the 3.5mm TRS input connection? If not how is your wireless microphone's output being connected to the input(s) of the speaker?

According to what I can find out the Behringer Eurolive B212D does not have wireless capability.

If you do have some sort of wireless microphone interface equipment connected then I'm assuming that you have got it setup somehow as per the image below. If not and your wireless microphone is 'connected' to another piece of equipment for it to work, check its' connection to the speaker(s) and ensure that it is connected to the appropriate input and setup as per below depending on input connected.

If the microphone? is connected to the XLR input (as shown in the image) set the level adjustment on both the speakers half way between the centre (vertical) position and the maximum position. (turn the selector clockwise).

If the microphone? is connected to the 3.5mm TRS input socket set the level adjustment on both the speakers half way between the centre (vertical) position and the maximum position. (turn the selector anti-clockwise)

By speaking into the microphone, adjust the level adjustment on both of the speakers to get the desired volume. (Also check the output level of the wireless equipment?- if any- to see that it is not set too high). If the clip light comes on (on either speaker) it is too loud and needs to be scaled back until the light goes out. Also adjust the equalizer controls on both speakers to get the desired 'sound'(bass and treble mix)."

"RE: Teixeira

When you run an amp into clipping, quite often bad things happen. The initial thump is probably because the protection circuit has not completely engaged yet or is somewhat defective. Basically the amp section now needs some work. I would expect to find that the output transistors are shorted. I believe that this unit uses discrete transistors for outputs. This should be a fairly simple repair for an experienced amp repair individual.
