Description
Atom DAC (with 15VAC Power Adapter)
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. |
