ES-3 mk4 Lightpipe/CV Interface

February 2017 sees the launch of the “ES-3 mk4”. Functionally equivalent to the ES-3 mk3, the mk4 adds these improvements:

  • Illuminated jack sockets
  • Less deep

The ES-3 is a Eurorack format module which converts eight channels of ADAT Lightpipe input to DC coupled outputs on 3.5mm jacks, for the ultimate convenience in connection of a DAW directly to analogue synthesizers. The outputs can be used as control voltages (CVs), for example with software such as Expert Sleepers Silent Way, and can also be used as audio outputs at high, modular synth-compatible levels. With the ES-3, a single optical cable is all that is need to bring direct CV control from your DAW right into the heart of a modular system. ES-3 mk3 September 2013 sees the launch of the “ES-3 mk3”. Functionally equivalent to the ES-3 mk2, the mk3 adds these improvements:

  • Higher spec DACs and lower noise circuitry
  • Easier access to the expansion headers
  • More robust ADAT port
  • More visible LEDs

Specification:- Standard configuration

  • Input connection: optical, ADAT Lightpipe standard
  • D/A conversion: 24 bit, 105dB SNR typical
  • Output connections: 8x 3.5mm jacks, DC-coupled
  • Maximum output voltage: approximately ±10V DC
  • Indicators: LED for ADAT clock sync; 2 LEDs per channel indicate output voltage (+ve/-ve)
  • 53mm module depth
  • Doepfer and Analogue Systems slot mounting holes
  • +/-12V Doepfer-style power connector
  • Panel size: 8HP

The module is available as standard with a black aluminium, orange aluminium or translucent black acrylic front panel.

96kHz compatibility

The ES-3 produces 8 outputs as normal when the ADAT interface is operated at 44.1/48kHz. In double speed mode (88.2/96kHz), the ES-3 outputs 4 channels, duplicated across pairs of outputs (ES-3 outputs 1/2 carry ADAT channel 1, outputs 3/4 carry ADAT channel 2 etc.). However, users of Silent Way can take advantage of the Silent Way SMUX plug-in to interleave CVs on the 96kHz stream, restoring the number of usable CV outputs to 8.
