Setup is extremely simple:
- Install the module in a suitable Eurorack case.
- Connect a TOSlink optical cable from the ADAT output of your audio interface to the input of the ES-3.
- Turn on.
That really is it. There are no switches, trim pots etc. to set up or configure.
The ES-3 is now acting as an extension of your audio interface. Any signal you want to come out of the ES-3's outputs, simply route in your DAW to the interface's ADAT output channels.
The power connector is Doepfer standard. If using the power cable supplied with the ES-3, the connector is keyed and will only insert into the ES-3 the correct way round, in which case the red edge of the cable is nearest the edge of the PCB, and carries -12V. Be sure to connect the other end of the power cable correctly, again so -12V corresponds to the red stripe on the cable.
The ES-3 can safely be used in a ±15V system with a suitable adaptor cable.
