Hi folks, I am having some noise problems. I am using 2 Behringer 8 channel preamps into a 2408MKll via ADAT. I have gone to the MOTU audio setup window and set the time code to Bank B optical. I am using bank A as analog. It doesn't matter if I set it for Bank B or C I am getting a timed noise when record is enabled in DP. It is like an intermittent white noise. If I have it set on Bank C the noise is on Bank B. It doesn't have much of a signal but it still cannot be there. Any help with this problem would be greatly appreciated. Thank, Jim

interesting. so, have you tried clocking the preamp from the 2408mkII? at a guess, the behringer's clock isn't stable.
good luck with this one. QUOTE (mcevill1 @ Fri 18 Jan 2013, 15:47)  Hi folks, I am having some noise problems. I am using 2 Behringer 8 channel preamps into a 2408MKll via ADAT.

Thanks for the suggestion.

I have tried it with one of them but there is only one BNC input on the 2408 QUOTE (mcevill1 @ Fri 18 Jan 2013, 15:47) Hi folks, I am having some noise problems.
