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.
One LED per channel shows gate activity.
The module is passive and consumes no power
