Hey there,

I have a SoundCraft MPM 12 mixer. I plug my iPod in at live events using generic Radio Shack 1/4" cables. Last week, I did a gig, and there was no signal on the iPod until after I turned phantom on. Every now and again the iPod faded out and wouldn't come in again until I flashed the phantom. The next night, I had no problems whatsoever. Was this a freak event, or do I need new cables, or is my mixer starting to go bad? I sincerely hope that one of you guys know what the problem was/is, and that it is not the third option.

Soundcraft questions in a Presonus forum?

Phantom power is applied to the XLR inputs not line inputs, unless you have an XLR inputs and using +4 line levels padded to the right operating levels. There is no 48v on the 1/4 line level inputs of any console. I think it may be junk cables...

Difficult to say, but indeed, normally there is no phantom power on the 1/4" inputs. I would suspect oxidation or dirt in the input jacks, or indeed your cable going bad.
