Simplified Audio, Re-engineered

We designed the Element Line for precision fit and function. EL DAC II furthers the exceptional performance of its predecssor with relay muting, an XMOS based USB Class 2 engine with MEMS oscillator, transformer isolated coaxial input, and higher performance optical input. Stack with EL Amp II for single button switching between headphones and speakers.

Features

MEMS Oscillator

EL DAC II's USB engine is clocked by an SiTime MEMS oscillator with ±10ppm frequency stability, 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 13 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 a AK4493EQ DAC is summed by a low noise NJR output stage, with DC coupling throughout. Drive any load you wish.

Transformer Isolated S/PDIF

Coaxial S/PDIF input is isolated using a Pulse transformer to minimize the possibility of ground loop noise.

4-Layer PCB

EL DAC II is built an a 4-layer, star grounded printed circuit board with proper 90-ohm characteristic impedance of its USB input.

Upgradeable Firmware

Our custom XMOS based firmware configures and manages EL DAC II's USB input and AK4493, with DFU support for possible future feature additions.

EL DAC II Instructions (EN)
EL DAC II - Optional Firmware v1.6.6

EL DAC II firmware v1.6.6, dated 04/02/2021, is recommended for use with most operating systems.

This version supports UAC2 with auto fallback to UAC1 when connected to a USB 1.1 hub or isolator, and supports connection to Android and iOS devices without a USB hub.

For more information and Installation guidance, please see Custom Firmware Builds.
EL DAC II - XMOS Drivers v4.13.0

No drivers are required for Mac OS, Linux, or Windows 10.

You may optionally install the XMOS drivers in Windows 10 to enable ASIO support.

XMOS drivers are required for Windows 7/8.
