Each unit has a bipolar attenuator, a so-called polarizer for attenuating and/or inverting a signal. The gain is at 2. The second control of each channel adds an offset voltage to the signal.
The signal at input 1 is sent to input 2 if there´s no cable inserted which gives you the possibility to process one signal in two different ways. If theres´no cable at output 1, signal 1 is being mixed with signal 2. Furthermore you can use each channel as an independent offset generator when nothing is patched to the input.
One input and one output per channel.
