The Hex I/O Expander module adapts six audio or CV signals connected to the front panel to SynQuaNon Audio and/or CV Bus connections on the rear. 
 
The module is entirely passive. Conversion can be from 3.5mm jacks to SynQuaNon Bus or the reverse. This facilitates interfacing SynQuaNon modules with other brands, as well as adding six additional inputs and/or outputs to SynQuaNon modules. 
 
Ideal for guitar multi-channel, single-string, or hexaphonic effects processing.
