As I've said before I am constantly thinking of ways improving the design of the room and any additions that may be useful so I came up with another idea. If you remember I have have a double garage next to the outbuilding but disconnected, where my electrics are drawn from and the fan is located. I figured that maybe in the future I might want to use that room as a live room so some audio feeds from the outbuilding into the garage might come in useful. With this in mind I did a bit of searching and found a supplier of multicore cable (Connectronics). They had listed some off-cuts of various types and there was a 5m length of 16 pair installation type multicore. This has all the required wires for mic/instrument applications but without the individual jackets, so you can't simply solder directly to a XLR/Jack but is perfect to wire into a stage box or panel (ideal here). I did some checking to see if 5m is long enough and it will work perfectly and at only £10 + £5 delivery! I phoned them first to check it was in stock and yes - so I ordered it.
