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.
