Ive got a problem which I recon must have a simple solution but Im missing something. Im using an Allen & Heath Xone92 and EFX 1000.

The send and return isnt as I imagined because it returns to the mixer on the mic channel but doesnt cut out the sound that was sent ( if you know what I mean???). Example. The Trans effect chops up the sound, but that cant happen if the source sound keeps playing. Ive got it set up with the main output going to the EFX then to my monitors but this isnt how I want it hooked up as than it can effect individual channels.

Does anyone know how I can fix this?

I appreciate the help. Thanks
