  1. Hi I have a project wherein i need to wire 4 stereo channels playing different music in a bus with 32 seats. Each seat should have a module to select one of the 4 channels and listen to it by plugging headphones in a 3.5 mm jack on the seat module. We have built the music system with 4 stereo outputs and we have also created a small seat module with amplifier which takes in stereo input and sends out amplified stereo output. Now I need help with distributing the audio. If I connect the 4 channels to the 8 wires on a CAT5 cable and run it across the bus, drawing out a parallel connection for every seat and also run 2 seperate wires along for power and ground, which are also drawn out for each seat module, would this method work? Is there a better way to distribute multiple channel audio across 32 seats in a cost effective way? Additional Info: the input impedance of the amplifier circuit at the seat units is 150k ohm and the length of the bus is 10m. (Around 25m cabling) Would the voltage drop be significant and would it require another amplifier / repeater ?
