I connect a Universal Audio 4-710d preamp unit to my Presonus Quantum interface via the ADAT optical ports. When I play my bass through the 4-710d there is signal noise in the form of pops and cracks. I have tried connecting the analog out from the 4-710d instead of the ADAT and it sounds fine. I also have run directly into the Quantum interface and have no issues. There is only noise introduced when I transfer through the ADAT ports.

Has anyone else experience signal noise issues when connecting outboard gear via the ADAT ports on the Quantum interface?

Thanks

Mike

I use a MOTU intreface with ADAT out to Quantum 2 ADAT in. Quantums clock set to internal and connect its word clock out to word clock in on the MOTU device which is set to external word clock. Quantum sample rate set at 48Khz.Everything works but still get a few small ticks and pops at 48K with MOTU set at 256 block size etc.
