Simplified Audio, Re-engineered
We designed the Element Line for precision fit and function. EL DAC II+ furthers the exceptional performance of its predecessor with relay muting, an XMOS based UAC2 engine with PCM and DSD support, transformer isolated coaxial input, and higher performance optical input. Optionally Add a BT5 Module, or Add Balanced Outputs for the flexibility of connecting to any amplifier. Stack with EL Amp II+ or EL Amp II+ Balanced for single button switching between headphones and speakers.

Features
MEMS Oscillator
EL DAC II+'s USB engine is clocked by an SiTime MEMS oscillator, delivering pristine jitter.
Relay Muting
Microprocessor controlled relays are standard in EL DAC II+ so that power up and input mode changes are free of audible transients.
USB Audio Class 2
EL DAC II+ supports up to 32/384kHz PCM over a custom XMOS XU208 based UAC2 engine. While we claim no measurable superiority of high sampling rates, UAC2 and ASIO support satisfy your pursuit of bitperfect listening.
Externally Powered
EL DAC II+ is powered by a perfected supply network, with an external AC transformer and 14 regulators that ensure consistent rail voltage and super low ripple. Never be bothered by USB hubs or OS power difficulties again.
Light Ring
Enjoy the presence of your EL DAC II+ with front and center mode selection via a touch-sensitive light ring.
Differential Summing Output
Differential output of an ESS Sabre DAC is paired with our unique, DC coupled, precision tuned I/V converter with three stages per channel, or six NJM opamps in total. Optional Balanced TRS Outputs and single-ended RCA Outputs provide flexibility of connecting to any amplifier.
Transformer Isolated S/PDIF
Coaxial S/PDIF input is isolated using a Pulse transformer to minimize the possibility of ground loop noise.
ASIO and DSD Support
EL DAC II+ provides an ASIO endpoint and automatic handling of PCM and DSD playback. Live sampling rate and status mode information is available in the XMOS control panel.
Upgradeable Firmware
Our custom XMOS based firmware configures and manages EL DAC II+'s USB input and DAC, with DFU support for possible future feature additions.
Optional Bluetooth 5
An optional Bluetooth 5.1 module feeds the received digital audio signal directly to the DAC via S/PDIF, relying on ESS's patented jitter recovery to deliver maximum performance from the wireless transmission.

XMOS Driver v5.30.0 for Win 10/11
XMOS driver v5.30.0 supports Windows 10/11, and is optional. No drivers are required for macOS, Linux, or Windows 10/11.
This driver enables ASIO support, provides the ability to view and adjust Buffer Settings (latency), supports 16/24/32-bitrates, and adds full DSD64-128 support to Atom DAC+, EL DAC II+, and Element III.
All XMOS based JDS Labs DACs are supported, including:
- Element II
- Element III
- EL DAC II(+)
- Atom DAC(+)
This driver is developed and maintained by Thesycon, and licensed to JDS Labs. Please find the full change log at TUSBAudio_history.txt.
-
Optional - XMOS Firmware Update Utility (DFU) for Win 10/11
This optional application for Windows 10/11 allows you to install firmware updates to XMOS based JDS Labs DACS, including:
- Element III
- Element II
- EL DAC II(+)
- Atom DAC(+)
To use, unzip the folder and follow instructions in the article How to Install an XMOS Firmware Update.
