I am newbie to modular analog (loving it), this is my first post here. 

I am looking for a 4 HP module to invert CV for envelopes as well as
invert audio for feedback patches. the description of the A-175 Dual
Voltage Inverter does not mention audio, only CV. Does it work well
with audio? 

The AS MX224 buffer/inverter/mixer specifically says it works on CV
and audio, as well as stating its range is -10 to +10vpp. My last
question is does the A-175 have as much usable range as the MX224? the
description only mentions 5v so I am unsure if it will distort at
higher levels. 

thanks,
