Once again, the phone system is mono, as in only 1 audio channel. You are apparently using a stereo source. Not a problem, try 'tip' and 'sleeve', I believe that will get you 1 channel of the stereo source. Don't even connect a wire to the 'ring' lug. And check with a buttset before you ever connect to the KSU. Test 1st and fix 1st. That way you will know that the source was good, before you hooked it to the KSU. Been there, didn't do that, wasted a lot of time. But only once! John C.
