Perhaps this is a very simple question, or not... I have a Sony RH-10 and bought a simple telephone adapter that sits between the headset and phone and provides a mono mic output. Works fine except... Sony records the mono imput on one channel. I would like to have it on both. Is this just a mini adapter mono2stereo? Could not find one at Fry's, but have not been to Radio Shack yet. Or is there a software solution with Sonicstage or other program? And btw, editing software ideas? Or is that best done in the RH10? Thanks in advance...
