I have the Eurolive B212A speaker,and the Xenyx 1202fx.I want to play my Ipod using this set up.Please help with connection

There are many causes of buzz, so it should be checked step by step :
- Bad connection on the input connector, or cord.
- Amplifier, basically have the block diagram like this:
If in one block damage, buzz can be heard.In the amplifier.
Generally occurs in the PSU and / or power amplifiers.
Fix it to the experts,because it requires a good knowledge of electronics.
Blown speaker cone, does not cause a buzz.
Short circuit along the wires supplying the audio, it will not cause any sound in the speakers, including the sound of music.
Try also, disconnect the input connector, whether the buzz is still audible. If after the input connector is removed, the buzz disappears, the possibility of buzz came from another device before the amplifier.

Hi, you can use the Control Room outputs to give you an additional output with it's own level control but of you want a separate "mix" rather that overall level you could try the FX send & use the FX controls per channel to set the mix - depends how / if you are using the FX of course! - Else upgrade to a mixer with 2 Aux sends - use one for FX & the other for monitor :-) e.g. some of the Alesis do this! 'Good Luck!

If the blue power light does not light up then there is a problem with the unit or power supply. As it is less than a year from purchase I would advise returning it to the shop.

Lots of luck. Behringer no longer sells direct. Fullcompass.com is their parts distributor. If they don't have it in stock, it takes months... I have had an order in for 6 months now. The procedure is you call Behringer at 1-425-672-0816 to get a part number and an incident type number. Then call Fullcompass and order the part at 1-800-356-5844 and tell them you need Behringer part. IF they have it in stock, then you are lucky.

Personally I would run the RCA outputs to the RCA in on the APS.
If you insist on using XLR from the APS to the board (like through a snake etc) I would higly recommend using XLR to 1/4" adapters. These things have wonderful little transformers in them (yes, wire wound transformers) that do the 1/4" to XLR conversion really nicely so that you can run your signal through the snake or just so that you don't get the hum and distortion that can be associated with unbalanced signal transfer.
You want a HI-Z unbalanced to LO-Z balanced adapter.
Not always easy to find, but if you absolutely cannot locate any, I have a couple in stock.
I suggest you look around though, because mine aren't cheap!

Try here... this is for a B212A but should be VERY close to the D version.

Here you go:

This is a STUDIO mic and CANNOT be used in the presence of speakers that are driven from its output.

There is special hardware processors to cancel feedback but you do NOT want to go there !!!

This condenser mic is to be used in a studio where performers wear earphones and NO monitors are present.

You should use a Shure SM58 or other CLOSE talking cardoids if you have speakers in the area.

just connect a baby plug to rca from the pc to the mixer respectively
