Getting Radio noise

[taki]

Hi, I am kind of new at this stuff, and I am having some problems with my ALTO L-12 mixer.

I know it`a not a good mixer, but it's cheapper than others

1. I am preparing for a live mixing, wich will be in the following days.

The problem is, that I get Radio when using a lots of microphones. I have 3 Behringer mic's, one cordless mic.

Sometimes, when I am using the multicore cable, the signal becomes stronger.

I also noticed, that some anonymus mic's have really strong radio singal!

Could you help me here? Some tips, and maybe some info to read about this kind of problem.

2. I need to connect 2 mixers, because I don't have enaugh tracks at my mixer? Last time, I've connected a 4 track behringer mixer to Alto L-12, using aux. return. Is this a good connection? I can't send the signal from the 2 mixers separetely, because at the amplifier, we can use only 1 input!

3. Because my mixer has only 6 XLR inputs, and the rest 6 are jack inputs, and I am using a multicore cable with just XLR, I am using converters, XLR-jack. Can this cause any problems???

Thank you for your help!

Ok, about the radio chatter. That could definitely be caused by your wireless mic. Do you know if it is VHF or UHF? It is also possibly that somehow your cables are picking up a signal, what kind of cables are you using?

I have Coardial mic cables.
