D1 Internal Converter

The D1 uses the AK4396 DAC, which is well-regarded for its low noise and high fidelity. Due to the high signal-to-noise specs of the AK4396 and the added benefit of double redundancy power source conversion and filtering, the D1 presents impressive low noise and low distortion characteristics. The D1 can process digital audio at any bit depth up to 24-bits and any sample rate up to 192kHz.

D1 Headphone Amplifier

The D1 includes a headphone amp based on the TI OPA2134 low noise opamp. The high-performance headphone output was designed for a wide range of headphones and will satisfy even the most demanding headphone enthusiasts.

D1 Power

The D1 is powered directly from the USB bus and power is passed through two stages of regulation to ensure no USB bus power variations affect the audio quality.

D1 Volume Control

Volume is controlled directly from the D1 front panel via the digitally-controlled analog potentiometer.
