Hardware Configuration Onboard PCI Sound J9/J10 – Analog Audio from CD-ROM Connectors Connect “AUDIO” output of the CD-ROM driver to these connectors. Panasonic compatible CD-ROM should connect to J10 (pin signals assignment is G-L-G-R), Sony compatible CD-ROM shouldconnect to J9 (pin signals assignment is L-G-G-R).
Chapter 2 J16 – Digital Audio Connector Connect this connector to the Digital Audio ribbon cable/ bracket that contains 3 jacks for Aux IN, SPDIF IN and SPDIF OUT device. Aux IN is used for the second Line-in port. SPDIF IN is used for input the external digital audio. Connect SPDIF OUT to the AC3 Audio Amplifier or Mini- Disk to play, and set the following jumper to select 5V or 0.5V signal level for used device.
Hardware Configuration Notice for PCI Sound application 1. Before you install PCI Sound drivers, make sure your operating system has already been installed. Otherwise the PCI Sound might be detect as "Other Device" by the device manager. 2. After the drivers installed, if you wants to use Software Wave-Table drivers as MIDI output device.
Chapter 2 The Four Speakers System Onboard Sound provides 2 wave channels (front/rear), known as the 4 speakers system. When application programs via DirectSound® 3D or A3D® interface locate the sound sources to the listener's back, the two rear speakers will work to enhance the rear audio positional effect, so as to complement the insufficiency of using only two front speakers to emulate the audio effect.
