HI, I am running an up-to-date RMX-1000 with my Condesa Carmen V. When I turn on the send return with the rmx, even with no effects active, there is a slight delay in the return, causing phasing problems so it sounds light a very tight delay. This seems to indicate the RMX is returning the signal with a slight lag.
Here is a video I took of it, you can clearly hear the problem as I turn up and down one of the four sends as well as the return.
Please note this issue is present on BOTH send/return and Master settings on the RMX.

Condesa is an extremely reputable manufacturer using full discrete analog circuity, so I highly doubt the problem is the mixer, but I'm still open to hear other opinions. The a friend of mine with the same mixer says he's used Line6's Echo Park with no problems.
Thanks
