AV-1 is a Eurorack format dual attenuverter with some extra functions. It can be used as a utility unit for control voltages or as an audio unit.
It has besides the obvious two attenuverter in and outputs, a summing output with an attenuverter to get more complex signals. This sums the signals after the A and B attenuverters.
When nothing is connected to A or B you can set the output to +/- 5V DC. This way you could run an LFO trough A, use B as a voltage offset and get the sum out on SUM.
The output A>B is a comparator output with a volume control. This can be used to trigger other units depending on whats coming out from A and B.
The A>B can also be used to make for instance a PWM signal out of a sinus in on A and a LFO in on B.
The A>B output is +/- 5V and a bit wave shaped so the square wave out should sound good if used for audio.
Next to each knob is a green/red LED showing the level and polarity of the output.
The green/red LED next to the A>B knob shows the signal before the red volume knob so you can se how the comparator reacts before turning up the volume.
The unit is 6hp wide and 25 mm deep including power connector.
