About the D1
The Pass Labs D1 DAC is a dedicated digital-to-analog converter known for its high-quality audio output. It utilizes four Burr Brown PCM63 DAC chips in a balanced configuration, providing a robust and precise conversion process. The D1 features a unique I/V conversion circuit using a single Mosfet device in common-gate single-ended Class A mode, which operates without feedback and maintains phase integrity. It offers fully balanced outputs with dedicated digital and analog circuitry for each channel. The output level is adjustable via a 24-position switch and precision resistors, ensuring precise tracking and neutrality. The specifications include an output of 3.6 volts at digital full scale, a frequency response of +0 / – 0.5 dB from 20 Hz to 20 kHz, and distortion of less than 0.02% THD at 3.6 volts. The D1 also features low jitter of less than 30 picoseconds and an unweighted noise level of -130 dB relative to full output.
