The other night I was using the 57 swithced out laptops with the other dj. Transition between laptops and 57 was fine. The next time we swapped out laptops I was only able to recieve audio from 1 of the 2 channels coming from serato. I tried swithing the phono line swithces on the back, and switching between both line returns and would only recieve 1 deck from serato. Threw on some vinyl and swapped out laptops again and had the same problem with getting audio from only 1 deck. At the end of the night I shut off the power on the 57 and juiced it back up and everything was fine. I dont know if anyone else has experienced this, or has any answers?

Thanks,
