I would like to have a single differential transmitter (DRV134 / DRV135) drive up to 50 differential receivers (INA134 / INA137). The idea is to have a line level audio signal that is distributed throughout a large building to amplified speakers. Each 1W to 4W speaker would have a differential receiver and a small audio amplifier attached to the speaker cone. Two twisted pairs (4 wires total) would supply line level audio (1Vp-p) and DC power to each speaker.
The basic question is can a single differential transmitter drive multiple differential receivers without degrading the quality of the audio signal. If this method would not work can you suggest a method that would
