(1) Product Description
SDC-1000, Dolby Digital Pre-Amplifier from Seodu InChip, Inc. is designed to
support today’s leading-edge digital audio format, Dolby Digital (also known as AC3)
and Dolby Pro Logic along with digital PCM and analog audio from PC sound cards,
creating unrivaled 3D sound effect by using maximum of 6 speakers. End-users will
be benefited from ultimate multimedia sound effects at very low cost, when he/she
watches DVD movie, play 3D games and listening music. Fully utilizing embedded
high performance audio DSP and 20 Bit ADC/DAC supporting 48 kHz sampling rate,
it will allows PC users to feel and get full satisfaction which they might have gotten
from expensive consumer audio.
To watch and experience thrilling DVD movies using PC, you must have DVD-
ROM drive in your PC system and install a well-known S/W DVD player, such as
PowerDVD, WinDVD or Cinemaster DVD, which supports S/PDIF Digital output in
sound cards like SB! Live from Creative Labs. And install SDC-1000 Dolby Digital Pre-
Amplifier and appropriate powered speaker kits or audio amplifier, then you can enjoy
ultimate DVD movie and sound coming out of maximum 6 speakers in your small
world without expensive DVD player.
To play games in 6 channel sound, install the sound card which supports
Aureal 3D API version 3.0 in your system, connect its digital output to SDC-1000
system and speaker kits, and execute 3D games supported by Aureal 3D ver 3.0 API.
Then you can play fantastic 3D games in multi-channel sound.
To listen and enjoy very high quality audio, connect the digital output of
sound card to digital input of SDC-1000 and play audio applications like WinAMP,
Windows Media Player. Then you will hear very high quality, low noise digital audio by
bypassing noisy analog output path of sound cards. Also when you enable various
surround effects which are usually available in high-end consumer audio, you will get
exotic and nice feeling when listening music.
Allowing 4 CH analog input from modern sound cards from Creative, Yamaha,
etc, SDC-1000 has no problem in fully supporting them. Even if sound card in the PC
system has analog output only, end-user can still use surround modes and get multi-
channel sound effects from just 2 channel analog input.
And also thanks to easy speaker mode setting, automatic speaker detection
and bass management, end-users do not need all 6 speakers from the beginning.
Simply start with 2 speaker system and later add and/or upgrade additional speaker
sets. It’s very easy way to use the system and also economical. There is no need to
discard your existing speaker systems when you use SDC-1000.
Lastly but not least, without sacrifice in performance and feature compared to
consumer audio products, you may use the SDC-1000 system in anywhere you want
to, other than PC environment.
