I want to build long 3.5 mm 4 pole connector cables. Cables go from PC, laptop, iphone to 10K input CMoy amp. Amp's input, output are 4 pole, for phone/mic headset, mic signal go direct from amps output to input, than through cable to device.
Anyone done this before? What kind of cable to use for L, R and mic? 3x twisted pairs, 3x shilded? Any ideas where to find?
