ATOM, STACKED
Atom DAC is built to pair with the enormously popular JDS Labs Atom Amp, adopting our latest XMOS based USB Audio Class 2 input stage with support for future firmware updates. A subtle light ring glows when in use, and automatically powers down during inactivity. A dedicated transformer ensures mains isolation. Stack Atom DAC with your Atom Amp and enjoy!
 |
MEMS OSCILLATORAtom DAC’s USB engine is clocked by an SiTime MEMS oscillator with ±10ppm frequency stability, delivering pristine jitter. |
|
|
UPGRADEABLE FIRMWAREAtom DAC’s XMOS based firmware configures and manages its USB input, with DFU support for future feature additions. |
 |
USB AUDIO CLASS 2Atom 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. |
|
|
EXTERNALLY POWEREDAtom 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 STANDBYAtom DAC automatically enters standby after 15 minutes of inactivity, powering down its light ring and D/A circuitry, and audio wakes up within milliseconds. Standby can optionally be disabled by loading our ‘sleepless’ firmware. |
|
|
DIFFERENTIAL SUMMING OUTPUTDifferential output of a AK4490EQ DAC is summed by a low noise NJR output stage, with DC coupling throughout. Drive any load you wish. |
