Is there anyone anywhere with a 560011 Multi room audio distribution unit for sale? Does anyone have the schematics of the unit? Is it possible to build a clone? I've just been given 7 x 560125R/2 amplifiers and I would like to wire up my new workshop facility with a single zone audio covering 4 zones and quite a long cable runs between amplifiers (approx 130m in total between all amplifiers). I know this is probably bringing up old technology and should be laid to rest but I would like to intergrate it with existing switches and wiring already in place in my building and only distribute via cat6 if possible?
