Atom DAC+ is clocked by 45/49MHz MEMS oscillators with ±25ppm frequency stability, delivering minimal jitter.
Atom DAC+’s XMOS based firmware configures and manages all functionality, with DFU support for future updates.
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.
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.
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.
