AUDIO SUBSYSTEM

The Advanced/RH offers three audio options for the OEM. The consumer audio option uses an onboard header to route
audio to a riser card in the I/O panel. Consumer audio also includes a wave table upgrade header for future expansion.
The business audio option includes mike and line jacks on the motherboard next to the mouse and keyboard connectors. A
third option is to have the board with no on-board audio.
The Advanced/RH audio subsystem is based upon the Creative Labs Vibra 16S audio controller and Yamaha OPL3 FM
synthesizer. The controller features a 16-bit stereo audio sub-system as a factory installed option along with the OPL3 FM
synthesizer. The Vibra 16S controller provides all the digital audio and analog mixing functions required for recording and
playing of audio on personal computers. These functions include stereo analog-to-digital and digital-to-analog converters,
analog mixing, anti-aliasing and reconstruction filters, line and microphone level inputs, and digital audio compression via
selectable A-law / µlaw, and full digital control of all mixer and volume control functions.
