I'm building a wall box for a new studio. Been considering wiring the xlr sockets on the faceplate to the loom of installation cable using those screw in terminal blocks to make it easier to service.

Just wondering, i think the conductors in the blocks are brass or something similar. Ive got a really horrible feeling that the join might cause lots of extra capacitance, the run is already 22m from the control room so i dont want to create any more problems than ive already let myself in for.

If someone could give an answer or suggest something that would be much appreciated.

Cheers.

I'm not sure what's going on here.
What kind of box are you screwing?

was building a box for the xlr sockets that would run across the building to the control room. wanted to make it possible to change a socket without resoldering, using terminal blocks or something like that.

in the end i realised i was being too anal and just soldered them. if was in case i ended up needing to run more guitar tie lines than i have or something like that. dont know what i was thinking of!

cheers anyway

its funny you mention wiring a terminal block inside your wall plate, instead of soldering direct lines. i was considering the same thing in my studio.

however ive opted for the "fuck it - spend more money" approach. which is basically, if i think i only need 12 xlrs in one room, get a 20ch snake. if i think only need 15ft for the cable line, get 22ft and leave the extra for the future. sure it costs more a little more, but i have lots expansion and repair options that don't involve running new lines through already built walls.

nice to see i wasnt being totally crazy!

its a 3 room rehearsal studio in a warehouse space so 2 of the runs are almost 80ft fully shielded in earthed conduit. But all three rooms have very different acoustics, ones so acoustically dead it always felt strange rehearsing in there.

Ive come to the conclusion that if i need to use the xlr lines for something else i can easily build a series of adapters to turn them into guitar tie lines or something like that. Not sure how a guitar will sound run unbalanced down 80ft of installation cable though! might need to build some signal conditioning modules to balance/unbalance stuff...

Its very nice to be able to have guitar, bass and drums in spearate rooms totally isolated, but playing together laying a live track down.

The terminal blocks i was looking at were designed for small signal digital stuff, so i assumed they would be low capacitance, but when i measured it i think the capaticatce of the connections coupled with the resistance of the long run would have definitely introduced some filtering effect to the signal, and probably some nasty signal loss. Amazing though, even over 80ft the signal sounds great. Once saw the BBC mix a live performance taken from a split before the desk running over 400ft down a multicore, and it still sounded great. So use quality cables and distance shouldnt be so much of a problem. Touch wood!
