An extremely useful module to have if you want to interface other equipment with your AE modular. The most important job is to prevent a CV outside the 0 to +5 volts range from entering the AE system as this would damage it.

Module power consumption: 0.2 mA

Inputs
I / O 1 - 3.5mm jack socket - mono signal sent to I / O patch socket 1
I / O 2 - 3.5mm jack socket - signal sent to I / O patch socket 2
I / O 3 - 3.5mm jack socket - mono signal sent to I / O patch socket 3
I / O 4 - 3.5mm jack socket - signal sent to I / O patch socket 4
They are labelled I / O as you can also send the signal input into the AE patch in / outs (in the AE system's usual location for outputs) and out to your external equipment via these sockets

If a stereo 3.5mm plug is used into sockets 1 or 3, the signals are output on patch in / outs 1 / 2 and 3 / 4 respectively.

Outputs
I / O 1 - This will output the signal from the I / O 1 3.5mm socket above, or send one to it.
I / O 2 -This will output the signal from the I / O 2 3.5mm socket above, or send one to it.
I / O 3 - This will output the signal from the I / O 3 3.5mm socket above, or send one to it.
I / O 4 - This will output the signal from the I / O 4 3.5mm socket above, or send one to it.
Mult - A passive mixing / splitter with no connections to main module circuits.

Controls
AUD / DC Switch - 1 for each 3.5mm socket - selects audio signal or CV type signal. For the AE this means a CV is 0 volts to 5V, with 0 as the base, for audio it "rotates" around 2.5 volts but still is 0 to 5 volts. If things are quite as expected, try the switch in the other position.
