Actually, when I send a sawtooth signal to my software
oscilloscope, it shows up mirrored on the screen. When I patch
the signal through the A-119 (Asym. In) before sending it to the
computer, the waveform looks the way it does on the front of the
module. So it seems that the A-119 inverts audio signals.

I believe the electronics involved in inverting a signal are
extremely simple (although I don't know what they are) which
makes me think it might be possible to fit the components into a
connector or something to be placed in between two patch
cables.
