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 congure 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 aect your output.
The D1 also contains a high-performance headphone amplier.
Note: When headphones are plugged in, the analog output will be
muted.

Troubleshooting
• I have connected my D1 as shown in the manual, but there is no
music output.
1. Check to see that the power light is lit. If not, try another USB
output on your computer.
2. Ensure that D1 is selected as your output device under Control
Panel (PC) or System Preferences/Audio (Mac).
3. Try another USB cable.
• I have connected my D1 to my TV/DVD/BluRay, but there is no sound
output.
1. Be sure that D1 is also connected to a USB power adapter, and
that the power light is lit.
2. Be sure that your TV/DVD/BluRay digital audio is set to “PCM
Stereo”.
• Only one channel plays through my D1.
1. Check the RCA cables between your D1 and your sound system.
2. Check your audio player to ensure that the balance is centered.
Break-In Period
Your DAC will sound great out of the box and will get better over time.
However, give it 40 to 50 hours break-in time before doing any critical
listening.
