Similarly, to indicate sampling frequency
of 192kHz, the 48kHz and the 96kHz
LEDs will glow.
Note: Windows does not support
192kHz sampling frequency. Owners of
computers (Windows) are required to
install corresponding software provided
in the accompanying CD-ROM. Simply
follow the software installation instructions contained.
As a USB interface
1. Connect the coaxial or Toslink optical
digital output on the Link D-1 USB D/A
Converter to a corresponding digital
receiver on your DAC as illustrated
below.
2. Your DAC or CD player with digital
inputs will lock onto the input data. The
display screen will then indicate the
presence of a digital signal and show the
output sampling frequency of the music
file in your computer.

Specifications
With the increased popularity of computers as source, this Link D-1 USB D/A Converter
allows consumers to enjoy listening to digital music sources from a computer (Windows
or Mac) via USB connection. This product is USB 1.1 and 2.0 compliant. This device
supports sampling frequencies ranging from 32kHz to 192kHz and incorporates a high
quality digital-to-analogue converter (DAC). It can also serve as an USB interface simply
to convert the data of music files from your computer to SPDIF signal for use with
outboard DAC’s.
As a digital-to-analogue converter
1. When switched on, all the LEDs on the
front panel will flash for less than a
second. This unit enters standby mode
when switched on and the power LED
glows red. It turns white in operation
mode.
2. Connect your computer and Link D-1
USB D/A Converter via USB link.The
factory default 48kHz input sampling
frequency will glow white.
3. Connect the audio output terminals to
the RCA unbalanced input sockets of
your pre-amplifier or integrated amplifier
using high quality, screened audio
cables.
4. With the computer in operation the
Link D-1 USB D/A Converter will detect
and lock onto input data and the USB
input indicator LED glows red.
Meanwhile, the source sampling
frequency indicator LED glows white.
To indicate a sampling frequency of
176.4kHz, the 44.1kHz and 88.2kHz
LEDs will glow.
