USB-C DAC

The Atom DAC 2 is the ideal companion to JDS Labs' Atom Amp 2 and Atom Amp+, and suits any other hi-fi use. Its USB-C and optical (Toslink) inputs make it compatible with many sources. It has a latest-generation XMOS interface supporting UAC2, with UAC1 fallback. Its front-panel light comes on during use and switches off automatically during idle periods. The DAC 2 is also more energy-efficient than its predecessor, thanks to a better-performing I/V stage, and it adopts an all-aluminium case.

USB Type-C

The Atom DAC 2's native USB Type-C input accepts up to 32-bit / 384 kHz PCM via a dedicated XMOS-based UAC2 engine, ASIO and DSD compatible. UAC1 mode, for the PS5 or Nintendo Switch, is enabled with the dedicated UAC1 USB cable.

More efficient

The Atom DAC 2 has an improved power supply, with an external AC transformer and 10 regulators ensuring constant rail voltage and very low ripple. It is also more energy-efficient than the Atom DAC+: it uses less power and runs cooler.

MEMS oscillators

The Atom DAC 2 is clocked by 45/49 MHz MEMS oscillators with ±25 ppm frequency stability, for minimal jitter.

Up-to-date firmware

The Atom DAC 2's firmware handles all the features of the XMOS chip and makes updates easy.

Automatic standby

The Atom DAC 2 automatically goes into standby after 5 minutes of USB inactivity, and wakes up instantly as soon as you use it. Its light ring is now fixed to the aluminium chassis for added robustness.

Metal case

The Atom DAC 2 is built in an aluminium chassis.

No more inline switch!

The Atom DAC 2 has a real power switch: no more need for the inline toggle switch supplied with the Atom DAC(+).
