The VIA Six-TRAC is a complete solution supporting
the AC'97 2.2 specification with S/PDIF extension compliance.
Enabling 6 channel outputs with 18-bit resolution the
VIA Six-TRAC can support full 5.1 surround sound enabling
theatre-quality home audio systems. For optimum playback
performance the Six-TRAC analog mixer circuitry integrates
stereo enhancement to provide a pleasing 3Ds surround
sound effect for stereo media. Further provisions in
the hardware allow for downmixing of 6-channel inputs
such as DVDs into 4-channel, or even 2-channels outputs.
An 18-bit independent rate stereo ADC enables 5 stereo
and 2 mono analog line-level inputs allowing recording
from sources such as microphones, CDs, line-ins etc.
With sample rate converters on all channels the VIA
Six-TRAC can be adjusted in 1Hz increments allowing
exacting audio manipulation. To maintain full digital
audio paths the VIA Six-TRAC has an IEC958 line driver
for S/PDIF compressed digital or LPCM audio outputs.
For easy integration by system designers, the VIA Six-TRAC
is designed with aggressive power management to achieve
low power consumption, a 3.3v or 5v power supply, and
a small footprint 48-pin LQFP package. Primary applications
of the VIA Six-TRAC include audio on motherboard solutions,
add-in cards, and any other system that can benefit
from high-quality 6-channel audio performance.
