[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 (±10ppm)
- 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-10.1 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…. The case of the device is the stylish
iron-gray whole aluminium one.
