I have a need for a remote audio mixer, Basicly I am trying to devise a way to do away with a Multicore cable.
My thoughts so far are either coded infrared tranmitter/receiver or RF I would like a single Xmit coded style rather than the use of multiples. The distance I am trying to acheive is approx 40 Mtrs.
I suggest you consider the bandwidth required!.
the end result should be 32 line or mike sources from a stage transmitted to a remote mixing desk to be processed. for the return trip of mixed signals I am using an AV transmitter/Receiver to the power amp box.
Am i reinventing a wheel, and if not is it feasable and do the costs outweigh what I am trying to do?
I don't think it's practicable, it would certainly be VERY expensive to do, and you are certain to run into licencing problems - it is something I've thought about a LOT over the years, and for the same reason
are there any down sides (eg degredation of Signal ect.)
You're certainly likely to degrade the signal, and you're reducing the control you have over it - at the moment the signals enter your mixer and you have instant control over them, with either a switched or variable attenuator, to keep the levels within a sensible range. You would need to do this at the transmitter side, in order to keep the transmitted levels within the far tighter levels that the transmitter would need.
My thoughts over the years have been towards a remote controlled mixer, with the mixer on stage but digitally controlled via a wireless data system, this would overcome the problems associated with trying to send multiple audio paths wirelessly.
I've just bought a cheap small snake, 15m long and 8 inputs 4 outputs, used it for the first time yesterday, it went very well
I suggest you look what proffesionals do?, I'm sure they all use multi-way cables - wireless just isn't reliable enough, or of good enough quality. I presume you've often come across wireless mike or guitar problems, and ended up using a cable!.
