Expert Sleepers ES-3 Eurorack ADAT Lightpipe/CV Interface (MK4)

Expert Sleepers

In stock.
Shipping info

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.

The ES-3's specifications are as follows:

  • Panel width: 8HP
  • Module depth: 50mm
  • 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; illuminated sockets indicate output voltage (+ve/-ve)
  • Current draw: 148mA on the +12V rail, 18mA on the -12V rail
  • 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.

ES-3 mk4

  • 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

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

ES-3 mk2
From January 2012 to August 2013, ES-3s were shipped marked "ES-3 mk2". These units had an identical specification to the orignal ES-3, but also included a couple of expansion headers. The first expansion module to make use of these was the ES-5.

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.

How much is my shipping?

Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK it's normally around £4 for order values under £150, and free above that. Shipping to mainland EU is typically between £7 and £20, depending on the shipping method and the size and weight of the order.

Do you ship to my country?

Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.

Shipping methods

We use a combination of Parcelforce, DPD, Royal Mail and UPS for the UK, and for international orders it's either Royal Mail, UPS, DHL or FedEx depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.

Dispatch times

For UK orders, we normally dispatch the same working day if we get the order before 15:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.

For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes FedEx or UPS may come a little earlier than scheduled which would also push an order into the next day.

Shipping times

Since April 2020 the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer.

There is absolutely nothing we can do about this unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.

Saturday shipping

If you're in the UK and you order before 15:30 on a Friday then we can send something for a Saturday delivery (NB: this applies to UK mainland addresses only). The success rate with DPD is about 95% so it's worth a punt most of the time. Please note that if you select Saturday shipping on an order placed earlier in the week, we'll wait until Friday to ship it.

Pre-orders

If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.

If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch if you have questions.
