This is handy utility module you find it's way in to nearly every patch you make. The three knobs are spaced well and can act as active attenuators, attenuverters (bipolar) and inverting attenuators according to the setting of the three-position switches.
Each input is normalled to a DC voltage selectable via jumpers for each channel to be 5 v or 10 v. With nothing plugged into the jacks, each knob controls a voltage amount. So if the rear jumper for channel a was set to 5 v then the knob a would control the following ranges on output a: position 1: 0 to – 5 v, position 2: -5 to +5 v, and position 3: 0 to +5 v
- skiff friendly (single pcb)
- 3 modes for each channel
- 5/10 v normalling to inputs
- with external signals it acts as active/buffered attenuator/attenuverter/inverter/mixer
