Latency Using Analog Ins (US1800)

[elbandito]

When I plug my preamp into the US1800's 1/4" jacks on the back of the unit, I experience latency issues. When I use the spdif out on my pre, it comes thru without a problem. This seems strange to me. I'd figure that it'd be the other way around... Any ideas?

That does seem strange. I use multiple outboard preamps as well as spdif and have never experienced that. I'm stumped.
