It supports Dolby(TM) Digital, and Digital Theatre Sound (DTS(TM)) using Yamaha's YMF744 and YSS912 audio chips. The new audio card provides a variety of surround effects from church, jazz, hall, disco, live, stadium and theatre using a sub-DSP (digital signal processor) in the Yamaha YSS912.

XG-Movie 5.1 Digital Surround Card outputs 5.1-channel audio (left, center, right, left-surround, right-surround, center and LFE, sometimes referred to as subwoofer) that delivers cinema quality effects. The card accepts both analog and digital input sources and provides both analog and digital output. Signal to noise ratio (S/N) is greater than 96 dB.

Villafuerte, director of sales and marketing, Yamaha Systems Technology Inc. ``We combined technologies from our AV division, Music division, and PC Audio division and backed them up with world-class semiconductor manufacturing, to bring the ultimate audio experience to today's consumers.''
