Expert Sleepers ESX-8GT Mk1 (active)


The ESX-8GT is an gate expander module for Expert Sleepers´ ES-4 to offer eight digital outputs for use as gates, triggers, clocks etc. The Mk1 version is active and can generate gate signals with +12V level.

One last ESX-8GT Mk1 in stock (As of March 11th, 2014)



Up to five ES-4 Gate Expanders can be attached to one ES-4 - one per ES-4 channel. (The 8 outputs of the Gate Expander reflect the 8 bits of CV information passed to the ES-4's DACs.) Therefore you can combine the modules to create a system with up to 40 independent gate outputs - all driven from a single S/PDIF connection.

The eight outputs of one expander correspond to the eight bits of the CV information at the digital/analog converter of the ES-4.

Output voltages: 0V/5V or 0V/12V, selectable via jumper in groups independently for channels 1-4 and 5-8.

One LED per channel shows gate activity.
