4I / O offers four minijack sockets that are connected to the AE sockets for connecting external audio sources, CV's and Eurorack modules. Sockets 1 and 3 are stereo sockets; if a stereo cable is inserted here the signal is available on sockets 1 / 2 and 3 / 4. With mono cables the four sockets can be used independently.

All sockets have an overvoltage protection (as AE modular is limited to 5V) and can be switched between audio and DC / CV signals.
