[Features]
In the front panel, there are the USB socket
and the headphone socket (can convert to a pair of RCA
audio output with the bundled adaptor). The back panel
is mainly the digital outputs (optical x1, coaxial x2
(RCA & BNC), AES/EBU x1) and the external power
supply socket.
- high-end Burr Brown PCM2704 IC
for USB audio conversion
- proprietary dual
power regulation circuits design (normal implementations
are just directly apply the 5V USB bus power). No matter
the power is supplied from the USB bus or from external
socket, it is regulated before supply to the related
ICs. Dual regulated powers are supplied to digital
circuits and analog circuits individually.
-
separated digital/analog ground. The digital GND
(network) and the analog GND (solid) is totally
separated except connected via a ferrite bread in a
single point. It effectively reduce interference between
digital signals and analog signals.
- Option to
use USB bus power [convenient] or external power [better
sound] (e.g. AA size rechargeable battery 1.2V x4=5V,
don't use normal batteries with 1.2V x4=6V, it would be
too high for safety and good sound performance)
- 4pins high accuracy crystal clock (¡Ó10ppm)
- applied RS422 driving IC to concurrently drive
4 groups of balance & non-balance digital outputs.
Audiophiles can compare the differences between these
digital outputs instantly or play for the Bi-DACs or
even Quad DACs.
- proprietary impedance matching
circuits for AES/EBU(110ohm), Coaxial(75ohm) digital
outputs
- applied the specially designed pulse
transformers for each AES/EBU and Coaxial outputs to
further isolated interference from UD-10 to the external
DAC. The most pure, accurate, standard digital signal is
then regenerated with minimum interference and jitter.

- plug-and-play
without driver installation for most PC/Mac operating
systems, e.g. Windows 2000, Windows XP, VISTA and Mac OS
X
We applied audiophile grade materials and
electronic components, including the high-quality
Japanese/Korean precise SMD resistors and capacitors.
Besides reducing the space, it also reduces the resident
inductance (relative to DIP components). The power
filtering and decoupling is using Sanyo OS-CON
solid-state electrolyte capacitors. The analog signal
decoupling and coupling are using ELNA Silmic
electrolyte capacitors and WIMA MKP10 film capacitors¡K.
The case of the device is the stylish iron-gray whole
aluminium one.
