All Metal, Custom Engravable, USB Type C

Atom DAC 2 helps your get the most out of your JDS Labs Atom Amp 2 or Atom Amp+, ensuring that your amp delivers its rated power. Equipped with USB Type C and TOSLINK inputs, Atom DAC 2 runs on our latest upgradeable XMOS-based firmware, supporting UAC2 and UAC1 fallback*. Its subtle light ring glows during use, automatically powers down during periods of inactivity, and wakes up instantly and silently. Additionally, Atom DAC 2 operates cooler due to a more efficient I/V stage, and its new aluminum enclosure is custom engravable!

Questions & Answers

What cables do I need?

Atom DAC 2 ships with a USB A-to-C cable and power adapter, the essentials for connecting to a PC or Mac.

You may also need a set of RCA cables to connect to your amplifier, or a TOSLINK cable if you plan to connect to an optical (S/PDIF) audio source.

Do I need to install drivers?

No. Atom DAC 2 is plug-and-play on Windows 10/11, macOS, Linux, iOS and Android. Our optional XMOS drivers enable ASIO support.

Can I hook it up to my vintage receiver or powered speakers?

 Yes, Atom DAC 2 provides standard RCA line-level outputs at 2 VRMS.

  • Receiver: use any line input, such as AUX, CD or Tape. Don’t use PHONO.

  • Powered speakers: Control volume at your speakers, or use Atom Amp 2 as a preamp.

Will this work with my PS5 or Nintendo Switch?

Yes, you will need a UAC1 Fallback cable. PS4, PS5, Nintendo Switch and Switch 2 all require USB Audio Class 1 (UAC1). For TVs or consoles with an optical output, you may instead use a TOSLINK cable.

Atom Stack or Element IV?

An Atom stack is plenty if you only need more volume, or need to connect to an analog source such as a turntable. Element IV is an end-game experience. Soundstage is perfect. Core unlocks PEQ presets for your headphones, along with Crossfeed, Loudness, and adjustable stereo width. And Element IV's knob is unlike anything you will find elsewhere, with its discrete optical encoder and smooth feel.
