Expert Sleepers ES-8
Eurorack USB audio interface with ADAT expansion
8 HP Eurorack module
The ES-8 is a Eurorack USB audio interface that provides four analogue inputs and four analogue outputs, bridging a modular synthesizer with a computer or iOS device for use with DAWs and CV-generation software. It also supports ADAT expansion for additional channels via ES-5 and ES-6 expander modules, and can operate standalone as an ADAT-to-CV converter without a USB host.
