Overview

The D1 24-bit DAC is a simple yet powerful digital-to-analog converter, with performance and features usually found only in much more expensive DACs. It can accept USB or PCM-stream optical inputs, and will automatically configure to match the inputs you deliver, with the optical input being dominant.

The D1 can process digital audio at any bit depth up to 24 bits, and any sample rate up to 192KHz. The D1 USB input can accept a USB audio stream from your computer or other USB source device. The D1 optical input can accept optical (PCM stereo) streams from any optical (TOSLINK) source, such as TVs, Apple TV ^® , DVD/BluRay players, CD players, etc.

Note: optical sources must be set to PCM Stereo.

The D1 output can be connected to any gear with an analog audio input, such as powered speakers, a boombox, stereo system, etc.

Power for the D1 is provided via the USB bus.

Note: when using the D1 with the optical output of your computer, the USB port on the computer can provide power. The D1 will sense that an optical input is present, and give that input priority.

USB power is "double regulated" to ensure that no USB bus power variations affect your output.

The D1 also contains a high-performance headphone amplifier.

Note: When headphones are plugged in, the analog output will be muted.

• Ensure that D1 is selected as your output device under Control Panel (PC) or System Preferences/Audio (Mac).
• Try another USB cable.
• I have connected my D1 to my TV/DVD/BluRay, but there is no sound output.
• Be sure that D1 is also connected to a USB power adapter, and that the power light is lit.
• Be sure that your TV/DVD/BluRay digital audio is set to "PCM Stereo".
• Only one channel plays through my D1.
• Check the RCA cables between your D1 and your sound system.
• Check your audio player to ensure that the balance is centered.
