[Ham-Mac] TS-570 Digital Output and iMic Interface Issue

[Chris Smolinski]

In my case, I use an old Radio Shack audio mixer. I feed the audio 
from the various rigs into it, as well as the sound output from my 
Mac. The output of the mixer goes to the microphone inputs of the 
various radios, to the Mac's sound input, and to a nice pair of 
speakers. This lets me select audio from any radio, and the sliders 
let me get the optimum level from each radio. I can also vary the 
sound level into the Mac, and to the speakers for listening.

I have home-brew cables running to each radio, with a small audio 
transformer in case for isolation, to break any ground loops.
