expert sleepers es-3 mk4 price : $219.00

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.



modular patching with expert sleepers silent way and es-3 on vimeo. specifications:
the es-3's specifications are as follows:
panel width: 8hp
module depth: 53mm
input connection: optical, adat lightpipe standard
d/a conversion: 24 bit, 113db 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)
current draw*: 168ma on the +12v rail, 30ma on the -12v rail (198ma 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.

*current draw depends on sample rate and number of channels in use. given figures are maximums (48khz, all channels in use).

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. (see the video below.)
