USB 2.0 Class-Compliant Audio Interface

The ES-8 is a USB 2.0 class-compliant audio interface in a Eurorack module, with DC-coupled inputs and outputs that can be used for both CVs and audio. As such it is directly compatible with all popular computer-based CV generation software (e.g. Silent Way, Max/MSP, Reaktor, CV Toolkit, zMors, Audulus, etc.) as well as audio and CV processing iOS apps.

The ES-8 also has ADAT inputs & outputs. This could be used for example to expand the I/O count via an Expert Sleepers ES-3 and/or ES-6, or to connect a traditional audio interface to add, say, mic preamps or 1/4" line outputs (for example with the Behringer ADA8200).

Without a USB connection, the ES-8 can be used as a standalone ADAT-to-audio converter, providing DC-coupled I/O expansion for another ADAT-equipped audio interface.

An expansion header allows connection of an Expert Sleepers ES-5, to which in turn you can connect Expert Sleepers gate, CV and MIDI expanders.

The ES-8 has a high quality internal clock, and it can optionally sync to the clock from the input ADAT signal.
