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.
