I have a friend who`s asked me to install some audio cabling in in furniture showroom, bar & outside for open air gigs.
The scenario is as follows:
Over the bank holiday next weekend he has 5 bands playing outside (weather permitting) This music needs to be piped to his showroom & also the bar. In a nutshell the system has to be flexible enough so that the source could be in any one of the 3 areas & be piped to the other 2 remaining areas. The people operating this setup are not technical in any way so it needs to be simple to re configure.
Logistics:
All areas are 50 meters away from each other so that the cabling needs to be balanced. The cabling will run from the outside area to the showroom & from the showroom to the bar. I`m thinking 4 pair cable so I have sends & returns in both directions from the showroom to the stage & the bar.
In the showroom the system will plug into a domestic hifi amp with unbalanced inputs.
The bar may well wind up having an unbalanced system.
The PA rig will have balanced outs from mixer.
What I`m thing is that the balanced outs of the mixer will have the balls to supply the outfronts & both other areas wired in parallel. So I need to unbalance the signals perhaps with transformers. Can anyone see a problem with this solution & what ratio transformers should I use.
Any thoughts would be appreciated.
