Quad-channel attenuverter/attenuator and offset with faders
Lapsus Os is a four channel attenuator/attenuverter and offset. Designed with performance in mind, each channel can be set to either attenuate or attenuate/invert an incoming signal, adjust offset of an incoming signal, or with nothing patched to its input, generate a 0 - 5v or -5v± +5v offset. Switches on the back of the module invert the fader behaviour, allowing for the module to be mounted in either direction, for further customization and ease of use.
These merchants probably sell this module. Huh?
