Introduction
1.1 Product Overview
The AudioPlus 6400 3D is a stereo 16 bit PnP sound card. It is compat-
ible with Sound Blaster 16 and Microsoft Windows Sound System.
Especially it supports Plug and Play function for all interface. The
AudioPlus 6400 3D also supports MPU-401 interface for Wave Table
Synthesis upgrade and supports 3D surround sound function. What we
provide at the side of sound card are line-in jack, micro-phone jack,
audio output jack, and a 15 pin D-SUB multiplexed joystick/MIDI
connector.
If your PC motherboard BIOS supports Plug and Play (PnP) func-
tion, while PC booting, the motherboard PnP BIOS will locate I/O
resources for all interfaces automatically to avoid I/O conflict. But,
all of your interface cards using I/O resources must support PnP func-
tion. Otherwise, I/O conflict still occurs at sometimes due to PnP
BIOScannot find theinterface card whichdoes not supportPnP func-
tion.

1.3 3D Surround Sound
Our 3D surround function takes any ordinary stereo signal as input and
produces an output signal with dramatically widened stereo imaging and
enhanced realism. And requires no extra speakers or special encoding of
input signals.
You can turn 3D sound on or off by program CMMIX.COM at DOS.
At Windows you also can turn it on or off by Audio Rack mixer. And
you can run Windows applications DEMO3D to test 3D surround
sound functions.
1.4 What is SPDIF IN/OUT ?
SPDIF is a digital audio IN/OUT standard. It support a non-distortion
stereo 44.1K 16bit digital audio transmission. You can get digital audio
through SPDIF IN from CD-Audio digital output or the other digital
audio output. You also can output digital audio through SPDIF OUT to
those equipment’s that accepted SPDIF IN format.
The AudioPlus 6400 3D SPDIF IN function is design for non-distor-
tion digital recording from digital audio output of CD-ROM (or other
equipments), not for playing from these equipments. Therefore, if
you want to record from your CD-ROM digital audio output through
AudioPlus 6400 3D SPDIF IN, please connect CD-ROM analog and
digitalaudiocabletosoundcard.Makesure that volume of CD(analog
audio) in mixer is ON and volume of Dig-CD(digital audio) is OFF.
Then you can playing from analog audio and recording from digital
audio for the best effect. If you turn on the volume of Dig-CD(digital
audio) in mixer, due to some CD-ROM drive design,there is noise
input during CD-ROM door open or close. Besides, SPDIF can not
adjust volume. So we recommended you to follow the steps that de-
scribe above.

Hardware/Software Section 1 - Introduction
1.5 What is Plug and Play ISA Standards?
The ISA bus architecture allows allocation of I/O address spaces, DMA
channels, and interrupt levels among multiple ISA cards. However, the
ISA interface has no defined hardware or software mechanism for allocat-
ing these resources. As a result, configuration of ISA cards is typically
done with jumpers that change the decode maps for I/O spaces and steer
the DMA and interrupt signals to different pins on the bus. Further, system
configuration files may need to be updated to reflect these changes. Users
typically resolve sharing conflicts by referring to documentation provided
by card manufacturer. For the average user , this configuration process can
be difficult and frustrating.
A Plug and Play-compliant system can identify the Plug and Play ISA
cards and the resources they use, then program these resources so they do
not conflict. The conflict-resolution scheme used on Plug and Play ISA
cards essentially puts all cards ‘to sleep’, then reads the card identification
and the information about what the card can do and the resources it re-
quires. This information can include what resources are programmable
and over what ranges they can be programmed. With this information, the
system can configure the card in a way that prevents conflicts with other
cards in the ISA bus.
1.6 Wave-Table Upgrade Board
For saving one I/O port and one IRQ channel, we disable MPU-401 MIDI
device as default value. If you want to output by wave-table (MPU-401
MIDI device):
In DOS (also Windows 3.1), please run CMINIT.EXE to enable MPU-
401 MIDI device. In Windows 3.1, please add MPU-401 device drivers
at first. Click on “Drivers” icon in “Control Panel” of “Main” group.
Click “Add” button and select “ROLAND MPU-401” to add device
drivers. After reboot, please click on “MIDI Mapper”icon in “Control
Panel” of “Main” group. Select item ‘MPU-401 MIDI’ in ‘Name’ and
click ‘Close’ button.
In Windows 95 system, please run En_Disable MPU-401 MIDI device
program(MDEVSET.EXE) to enable MPU-401 MIDI device. After reboot,
click “Start” button, and then click “Control Panel” at “Settings” Menu.
Double click on the “Multimedia” icon and click “MIDI”. In “Single In-
strument”, select “C-Media inc. External MIDI (MPU-401)” item.
