A well thought out attenuator offset module!  Rather than using an attenuverter, the module features a polarity switch that inverts the input, allowing attenuversion using the full range of the knob instead of half, and without having to find the null at 12 oclock for silence.  If input B is unpatched, it receives input A, allowing multing of an input to two locations with different attenuation.  If Output A is unpatched, it is summed with output B.  Each channel can be muted as well. Features gain beyond 2x, allowing you to turn 5v modulation into 10v modulation.

• Two independent channels also useable jointly as a mixer or splitter
• In each channel:
  • Input and output jack
  • Gain pot with up to 2.1 amplification
  • Bipolar offset pot
  • 3-position switch:
    • Inverted polarity
    • Channel off
    • Normal polarity
• Offset setting is independent of the polarity switch
• Normalized input A can distribute the signal in both channels
• Normalized outputs can mix the two channels on out B
• Useable for audio
• Compact module
