Question about Edirol UA-25 External Sound System
I've been using my UA-25 for a year or two for recording yet all of a sudden (mid way through recording an acoustic guitar via a dynamic mic/XLR) input 1 no longer seems to work. All it does now is produce a high pitched shriek regardless of what i plug into it (numerous XLR and mic combos, guitars and jacks, etc.).
If I tap the mic hard enough i do still get a signal but it comes out like a bit-crushed mess. Input 2 started picking up jamaican radio for a while and now also is just whining and buzzing, leaving me with two seemingly busted audio inputs...
Audio playback and MIDI still works just fine, though....
So, is it completely busted or is there something I can do to fix it? (way out of warranty here, btw)
The UA 25 needs a GOOD quality USB cable, the thicker the better. Cable loss means that by the time the 5V power supply from the computer reaches your Edirol, the voltage has dropped to about 4V, which then has to be boosted back up to 5 Volts and inverted to -5V.
Cheap cables will hamper performance or prevent it working at all ( I lost 2 hours once with this problme ) . Also avoid using the FRONT USB connectors on PCs, use the connectors that plug direct into the MOBO on the rear of the chasis.

You'll need those big round things arround the cable:
