Expert Sleepers ES-40 SPDIF Interface

EXPERT SLEEPERS ES-40

The Expert Sleepers ES-40 module converts a S/PDIF input to five separate expansion header channels for use with their ESX line of expanders, such as the ESX-8GT, ESX-4CV, ESX-8CV, and the ESX-8MD. The module is basically the ES-4 sans CV outputs and DACs. 

Users can connect any audio interface to the module using a standard S/PDIF connector. 

Additionally, there’s a S/PDIF output that allows for data to be routed back to the computer. This output can be used with ES-40 expansion modules such as the ES-7 CV Input Expander. 

Like its predecessor, when combined with ES and ESX expansion modules, the ES-40 allows for a variety of signal generation, including CV generation, CV/Gate pairs, drum triggers, MIDI/DINsync, and Digital Audio. 

ES-40 FEATURES

• Digital input: coaxial S/PDIF, standard rates up to 192kHz
• Digital output: coaxial S/PDIF
• Indicators: LED for S/PDIF sync lock
• Expansion
• 5 headers for connecting ESX series modules
• Digital audio I/O header (I2S format) for input expansion (e.g. ES-7)
