Expert Sleepers - ES-9

The Expert Sleepers ES-9 is a 16-in/16-out USB audio interface for Eurorack. Thanks to DC-coupled inputs and outputs the module can be used for audio and CV. 14 analog inputs allows the simultaneous recording of a large number of sound sources from the modular system. Additionally eight DC-coupled outputs are dedicated for controlling the modular system via CV or for sending audio to the modular system. It is the perfect solution for integrating a modular synth and a laptop/tablet, either in the studio or when playing out at a gig.

The ES-9 is a USB 2.0 class-compliant audio interface compatible with software such as Silent Way, Max/MSP, Reaktor, CV Toolkit, zMors, etc. and can also communicate with iOS.
The module operates with 24-bit depth and the sample rate is selectable between 44.1 kHz, 48 kHz, 88.2 kHz or 96 kHz.
Fourteen inputs and eight outputs (3.5mm sockets) are available. Being DC-coupled they are compatible both with audio and CVs.
In total, the ES-9 offers sixteen input and sixteen output channels.
An expander header located on the PCB allows for connection an ES-5, to which in turn you can connect gate, CV and MIDI expanders from the ESX series, creating a very powerful system.
The optical Toslink sockets are SPDIF connectors, one input and one output. Using them you can conenct an audio interface, adding 1/4" line inputs, microphone pre-amplifiers etc.
In addition, the ES-9 has a pair of balanced 6.35mm outputs and a 6.35mm stereo headphone output with volume control. The balanced outputs are not DC-coupled and are used to connect to monitor speakers or a mixing console. The headphone output is DC coupled.
The internal mixer can form eight individual mono mixes from eight inputs. In the standard configuration, the mixer only controls the main output volume and provides a headphone mix of channels 1-2 with 3-4.
