Connecting a ZMX122FX to a H4N Pro recorder

My friends band use this mixing desk, and asked me to video some songs for them onto the above recorder unit. Initially they connected from the control room to the XLR inputs on the recorder.

The recorder just collects the sound signal no changes are made on it

This gave a nice clean sound but there was no depth to it, none of the effects and so on like reverb which were coming through their monitors came across.

They are novices to this desk and dont know what they are doing wrong - would it be better to come out of the RCA ports, if so how best do they mix the finished sound to them

Thanks in hope
