Attenuator expander for Bad Idea #18214
This expander module turns the attenuators on and off inside of Bad Idea 18214, removing the need for shunts. With the switch off, the associated channel can be used as a bidirectional cable converter. When the switch on, an attenuator is applied to the signal and the associated channel becomes a Eurorack to line level audio converter.

These merchants probably sell this module. Huh?
