Clock Noise On Motu 2408 Mkll Options

[mcevill1]

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
