Does it matter if all my looms are balanced?

I'm installing my kit based around an Allen and Heath GS3000 I have a load of looms from a previous studio I used to have 8 years ago, I've tested them and repaired any faulty ones, but my question is this - does it matter if they are all balanced? (pretty much all of them are balanced) In what instances would I need unbalanced looms? I have a loom with stereo jacks on one end and mono jacks on the other end - any idea what this should be used for? To give you an idea I've put a list together of the outboard , fx and desk - some is from the old place, some is new Desk Allen and Heath GS3000 FX Lexicon MPX100 Ensoniq D/P Pro Zoom 1201 Outboard Amek Purepath DMCL CLM DB400 CLM Expounder TLA 5021 Ivory Valve compressor Behringer Composer Pro compressor There is also a MOTU 828 mk2 in the equation Thanks for your help, and sorry for sounding like a novice but I've never carried out a full installation myself before and its a bit daunting to say the least.

Does your console have a patchbay? Most connections will be a balanced connection. The exception is the Insert Send/Return cables we've been discussing, and also any unbalanced gear you may have such as a consumer CD player or something.

No it doesn't have a patchbay. I have separate patchbays.

I found a user manual for the GS3000. http://www.allen-heath.co.uk/veterans/d ... _guide.pdf Around page 9 it shows the pinout connections.

Thanks for all your help
