The SEND on the XZ is intended for use with a DDJ-1000 or SP-16 for sampler use, and the return would be routed to one of the channel inputs. We don't recommend using an EFX or RMX unit with the SEND and returning it to an input channel as that would potentially create a feedback loop (if you were sending the master signal). Instead, we suggest connecting the RMX in series with the master output from the XZ to the input on the RMX, then output from the RMX to your speakers or recording device.
