VIA Vinyl™ Multichannel Audio Suite

The VT8237 South Bridge provides OEMs and motherboard makers with an unrivaled

choice of market leading integrated and onboard audio performance options,

delivering rich, warm surround sound at resolutions as high as 24/96 through up to

six- or eight-channel outputs. VIA Vinyl Audio and VIA Vinyl Gold Audio enable users

to enjoy music, watch the latest DVD movies, play games, record and create

content, and connect to the latest devices with crisp, clear performance,

representing the highest levels of audio quality in a mainstream integrated or

onboard solution.

VIA Vinyl Audio

The VT8237 South Bridge integrates the high-performance VIA Vinyl AC'97 controller

to enable six-channel audio support and the transfer of the highest resolution audio

possible over the AC’97 standard.

For the best audio performance, the VT8237 should be

combined with VIA Six-TRAC (VT1616) codec to enable

premium quality AC'97 surround sound. Supporting six-

channel outputs with 20-bit resolutions, the VIA Six-TRAC

delivers full 5.1 surround sound to enable theatre-quality

home audio and realistic 3D gaming sound effects on

mainstream PC systems.

The VIA Six-TRAC also features mixer circuitry that integrates stereo enhancement

to provide a pleasing 3D surround sound effect for stereo content. Further provisions

in the hardware include the DualMAX™ feature that allows for downmixing of six-

channel inputs such as DVDs into four-channel, or even two-channel outputs. The

Six-TRAC also integrates a unique CoolAMP™ architectural design that allows

motherboard makers to choose the best possible amplifier to maximize audio quality

and gain control, maintaining optimal performance of the Six-TRAC even in extreme

conditions.
