JDS Labs Atom DAC+ (EU Plug)
Refurbished unit in excellent condition repackaged with original accessories or accessories from compatible models and brands. All refurbished products are certified by authorized technicians.
Atom DAC+ is built to pair with the enormously popular JDS Labs Atom Amp, now with even higher performance, both USB and TOSLINK inputs, and our latest upgradeable XMOS based firmware with UAC2 support and UAC1 fallback. Atom DAC+'s subtle light ring glows when in use, automatically powers down during inactivity, and wakes up instantly and silently. A dedicated transformer ensures mains isolation. Stack Atom DAC+ with your Atom Amp and enjoy!
Atom, stacked.
Atom DAC+ What's new?
- Equipped with Higher performance DAC ES9018 chip
- USB and digital optical TOSLINK inputs
- Silent transitions when resuming from auto standby
- MEMS oscillators run at twice the frequency
- Standard support for UAC2 with UAC1 fallback
- Alternative firmware lets you experiment with tube-like sound
- Connection to Android and iOS no longer requires USB hub
Mems Oscillator
Atom DAC+ is clocked by 45/49MHz MEMS oscillators with ±25ppm frequency stability, delivering minimal jitter. The MEMS oscillators run at twice the frequency to accommodate the new DAC chip.
Upgradeable Firmware
Atom DAC+'s XMOS based firmware configures and manages all functionality, with DFU support for future updates. Connection to Android and iOS Devices no longer require a USB hub and Resuming from auto standby is now instant and free of transients.
UAC2 and UAC1
Atom DAC+ 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. UAC1 fallback is activated when using a USB 1.1 hub or isolator.
Externally Powered
Atom DAC+ is powered by a perfected supply network, with an external AC transformer and 10 regulators that ensure consistent rail voltage and super low ripple.
Automatic Standby
Atom DAC+ automatically enters standby after 15 minutes of inactivity, powering down its light ring and D/A circuitry, and audio wakes up silently and instantly.
Differential Summing I/V Output
Differential output of an ES9018K2M DAC is paired with our unique, DC coupled, precision tuned I/V converter with three stages per channel, or six NJM opamps in total.
