EL DAC II+ is available in one of two physical arrangements:

Add Balanced Outputs - Adds Balanced TRS Outputs and retains single-ended RCA Outputs to provide flexibility of connecting to any amplifier.

Add BT5 Module - Adds a high-performance Bluetooth 5.1 input module and antenna instead of Balanced Outputs. The Bluetooth receiver transmits the digital audio stream directly to EL DAC II+'s D/A converter. Supported protocols include:

  • apt-X
  • apt-X HD
  • apt-X Low Latency
  • AAC
  • SBC
  • Covered by our 2-year transferable warranty

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 a higher performance optical input. Optionally choose Balanced Outputs for the flexibility of connecting to any amplifier, or choose a BT5 Module for wireless streaming. Stack with EL Amp II+ or EL Amp II+ Balanced for single button switching between headphones and speakers.

  • XMOS Driver v5.68 for Win 10/11

    XMOS driver v5.68 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+, Atom DAC 2, EL DAC II+, and Element III (MK2).

    All XMOS based JDS Labs DACs are supported, including:

    • Element III (MK2)
    • Atom DAC 2
    • Atom DAC(+)
    • EL DAC II(+)
    • Element II


    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(+)
    • Atom DAC 2

    To use, unzip the folder and follow instructions in the article How to Install an XMOS Firmware Update.

  • XMOS Driver v4.13.0 for Win7/8 - EL DAC II

    Archived XMOS driver v4.13.0 is required for UAC2 in Windows 7/8. Alternatively, you may use UAC1 fallback.

    For Win10/11, please use the most recent XMOS driver v5.30.0.


  • EL DAC II+ Firmware v2.1.2

    Please install the latest XMOS Driver, then use the Optional XMOS Driver and XMOS Firmware Update Utility (DFU).

    Please refer to:

    Please refer to included README.txt for further information. Detailed installation guidance for all operating systems can also be found in the article, How to Install an XMOS Firmware Update
