Hi all, I'm currently in the process of rewiring my girlie 6 space rack. It contains : Rexer wireless receiver Omnitronic RLD-8 power distributor Boss GT-PRO (waiting for an Axe FX Ultra 8) ) BBE 386 Acoustic pre amp Marshall 8008 power amp In the rear I placed a patch panel for power in- out (Neutrik Powercon's), midi in- out, effects loop send and return (Neutrik locking jacks), speaker out L&R (Neutrik locking jack's). I still have 4 spaces left for balanced line out's and IEM inputs. It's all working out beautifully, except for the midi connections. When I connect these to the MFX, my wireless receiver starts to humm/hiss. The status led for the B channel also lights up, indicating it's receiving something. :? The midi connectors have only been wired to the pins. (Shields to the middle ones. The screws used to mount the midi connector should provide ground through the patch panel?) What should I do here ? Extend the shield wire to the connector chassis ? Or are there other / better sollutions? Thanks !
