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 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 output 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. An expansion header allows connection of an Expert Sleepers ES-5, to which in turn you can connect our 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. The ES-8's specifications are as follows: Panel width: 8HP Module depth: 50mm Current draw: 198mA on the +12V rail, 52mA on the -12V rail (at 96kHz) USB socket: Type B Driver suport: class-compliant USB 2.0 (no Windows support currently) Channel count: 12 in, 16 out Supported sample rates: 44.1kHz, 48kHz, 88.2kHz, 96kHz Audio sample depth: 24 bit Output connections: 8x 3.5mm TS jacks, DC-coupled Maximum output voltage: approximately ±10V DC Analogue inputs: 4x 3.5mm TS jacks, DC-coupled Input voltage range: approximately ±10V Digital I/O: 1x ADAT input, 1x ADAT output Expansion headers: 1 for ES-5, 1 for ES-6
