ES-5 mkII (ES-3 Expander)

The ES-5 is an expansion module for the Expert Sleepers ES-3 Lightpipe/CV Interface.

It piggybacks on one of the ES-3's stereo channels to provide eight gate/clock/sync/MIDI outputs on the ES-5 itself, plus further expansion headers to connect up to six expansion modules e.g. the ES-4 Gate Expander.

Specifications

The ES-5's specifications are as follows:

• Panel width: 4HP
• Module depth: 49mm
• Digital input: connection from ES-3 module
• Analogue outputs: 8x 3.5mm jacks, DC-coupled
• Output voltages: 0V/5V
• Indicators: LED per channel
• Expansion
  • 6 headers for connecting expansion modules e.g. the ES-4 Gate Expander
• Current draw: 8mA on the +12V rail, 0mA on the -12V rail (8mA total)

The front panel is drilled for both Doepfer and Analogue Systems mounting holes (using a 'slot' rather than a single round hole). The power connector is a Doepfer standard 16 way IDC, with -12V furthest from the top of the board.

Note that connection to the ES-3 is by a simple plug-in cable for the ES-3 mk2 only. The original ES-3 requires some soldering to add the required connections.

ES-5 mk2

From February 2014, the ES-5 is shipping in a revised "mk2" form, matching the look of the ESX-8GT mk2. There are no functional differences between the ES-5 mk1 and mk2.
