Dual boostable attenuverter

Flip boost is a 4HP dual attenuverter + amplifier.

Each channel has a potentiometer to adjust the attenuverter, and a switch to toggle between unity gain and boosted gain (amplification factor can be adjusted behind the module with a trimmer).

Flip boost can be used to amplify audio signals too !

Input 1 is normalled to input 2, and when nothing is patched on input 1, an arbitrary default voltage is applied (typically 5V, but adjustable between -12V and +12V, with a trimmer behind the module).
