Reply to S2 Soundcard going out after an hour set?

S2 Soundcard going out after an hour set? Purchased through djtt, so what should I do? It's been fine previously. Had it since release. It works normally (mix, cues, fades, etc.) for a bit, then just goes out.. around 45 min or so.

I've tried two different cables, rca and phono.. main & booth, all options.

Same thing over and over. Also tried with many different mappings, What are my options? I feel screwed..

when it goes "out" - it makes an "errr" sound and I have to restart it completely.

What should I be doing or can I do :eek:
