The only thing I'd have to add is that multicore is not actually designed to be used with microphones and mixers - it's a bit flimsy for that, as an XLR plug is designed for a much fatter individual cables. It's actually designed for those rectangular multiway plugs with lots of pins. If I was rebuilding my studio from scratch, I'd use full sized cable with braided shielding for all the looms. (The multicore was already installed by the time I moved in). It might need bigger ducting, but I suspect the interference rejection once the loom has been split into individual wires would be much greater. You don't need to have the wires outside of the outer shielding with a multiway plug, but if you have a mixer with XLRs or a patch panel... Cheers Daniel
