C. Product feature:
KingRex UC192 USB to S/PDIF D2D Converter is a high-qua ity computer
transport interface for those wishing to stream high-reso ution p aybacks to an
existing DAC. The UC192 can transfer from PC or Mac at 16bit/44.1KHz to
32bit/192KHz through S/PDIF & IIS outputs. The UC192 runs isochronous with an
adaptive c ock generator to auto sync with the host. The master c ock generator is a
c assy 1ppm TXCO unit with proprietary ow-jitter drivers for Windows & Mac. Direct
Sound, ASIO4ALL, and WASAPI are a supported and run smooth y. The UC192 is
housed in an ova cross-section a uminum case with b ack hairbrush po ish. It
measures 88*82*24mm. “The UC192 ships with Windows & Mac drivers that need
to be insta ed on your computer. An externa 7.5V power supp y is provided.

G. Technica infos:
 UC192 USB TO S/PDIF & IIS D2D CONVERTER DIAGRAM
KingRex UC192 designed by isochronous. Inside the main chipset, it has buffer area
for temporary storage stream data which he ps to decrease the jitter and signa ose as
we . The adaptive c ock generator here is for synchronous mode of audio bit stream.
The c ock frequency wi be adjusted automatica y to be synchronized with host. The
adjustment wi be done in a manner that the c ock variation wi have minimum
impact to the audio performance. Master c ock generator is a c assy 1ppm TCXO w/
proprietary driver ower jitter.
Working environment suggestion:
OS:
Windows: XP, Vista & Win7
Mac : 10.4 10.5 & 10.6 (SOME OLD MAC COMPUTER 只有 USB1.0 界面,所以它只
能使用到 UC192 的44.1K IIS OUTPUT)
P.S. In most of condition, the Windows XP and Mac 10.3 wi sti workab e with KingRex
UC192. But in some setting, the computer wi has interna conf ict to be work with
UC192. Our suggestion wi be updated OS system at first! Most of prob em wi be
so ved after renew OS system to Window Win7 & Mac 10.6.
Suggested software whi e using UC192 :
Foobar 2000 V1.1 (http://www.foobar2000.org/down oad )
ASIO component : WASAPI output
support (http://www.foobar2000.org/components/view/foo_out_wasapi )

I. Configuring the computer to UC192
Configuring a PC with Windows XP
A PC with Windows XP can use UC192 in two different ways: Direct Sound (DS) and
ASIO4ALL.
 Configuring a PC with Windows Vista or Win7
A PC with Windows Vista or Win7 can use UC192 in two different way: Direct Sound (DS),
ASIO4ALL, and WASAPI. DS is suitab e for p ayers which cannot operate WASAPI or for
Internet streaming. WASAPI(Windows Audio Standard API) is a standard interface for
audio p ayers which a ows to get the same performance of KS with app ication which
cannot operate in KS mode, at the cost of higher CPU oad.
Configuring a Mac audio output devices
Go to system preference and se ect sounds. The fo owing windows as shown, p ease
se ect UC192and ope the “AUDIO MIDI SETUP” for output samp ing rate/bits rate se ect
for output as indicated Figure 10

18
(Figure 10)
Configuring for Windows XP, Vista, or Win7
Open contro Pane and se ect Hardware and Sounds. Under Audio, c ick to open the
Manage Audio Devices window which wi show KingRex UC192.

(Figure 11)
Open contro pane and se ect hardware and sounds. P ease go the path foobar
2000-> Fi e->Preference->ASIO Virtua Device Editior-> ASIO4ALL contro pane ->
KingRex UC192-> SPDIF or IIS.
As happens with ASIO4ALL, press the “configure” button setup the ASIO virtua
devices.

(Figure 12)
Configuring ASIO output for Windows system
Go to system preference and se ect sounds. The fo owing windows as shown, p ease
se ect UC192 for output as indicated Figure 13. Under the UC192, the first device is
I2S output; the second device is SPDIF ouput.
