Hardware Introduction
1.1 Product Overview
The CMI8330 is a stereo 16 bit PnP sound card. It is compatible with Sound
Blaster 16and Microsoft Windows Sound System. Especiallyit provides C3D
HRTF positional audio, you can enjoy real 3D positional audio in games or
applications that supports DirectX 5.0 Direct Sound 3D or A3D. 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. The
proper ways of jumper setting are all clearly marked in Figure 2.1 and Table
2.1.
If your PC motherboard BIOS supports Plug and Play (PnP) function, While
PC booting, motherboard PnP BIOS will locate I/O resource for all interface
automaticallyto avoid I/O conflict. But, at first, all of your interface card that
using I/O resource must support PnP function. Otherwise, I/O conflict still
occurs at sometimes. Because PnP BIOS cannot find the interface card which
does not support PnP function.

Hardware/Software Section 1- Hardware Introduction
1.4 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 allocating 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. Forthe 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 requires. 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.
1.5 Surround Sound
Our surround sound upgrade board 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 encodingof input
signals.
Youcanturn surround sound on or off byprogramCMMIX.COM at DOS. At
Windows you also canturnit on or off byAudio Rack mixer. And you can run
Windows applications DEMO3D to test surround sound functions.

Hardware/Software Section 1- Hardware Introduction
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
Instrument”, select “C-Media inc. External MIDI (MPU-401)” item.
1.7 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. The S/PDIF IN/OUT voltage level is
5Vp-p TTLlevel. You can get digital audio through SPDIF IN fromCD-Audio
digital output or the other digital audio output (ex. Minidisc,DAT). You also
can output digital audio through SPDIF OUT to those equipments that
accepted SPDIF IN format.
This sound card‘s SPDIF IN function is design for non-distortion digital
recording from digital audio output of CD-ROM (or other equipments), not
for playingfromtheseequipments. Therefore, if you want to record fromyour
CD-ROM digital audio output through SPDIF IN, please connect CD-ROM
analog and digital audio cable to sound card. Make sure 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 fromdigital
audioforthebest 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 describe above.

Installation of the CMI8330
2.1 Installing the CMI8330 into your Computer
WARNING: Before installingthe CMI8330, you should familiarize yourself
with major parts of it. Improper use of it may cause permanent damage to itself
and/or your PC and/or external equipment's.
Please follow the steps carefully for a typical system.
1. Turn off your computer and disconnect all power cords.
2. Removethe coverfromyour computer.Referto your computer systemuser's
guide for more details.
3. Choose an empty 16 bit ISA slot. (Preferably away fromother cards to cut
down on noise and interference).
4. Remove the expansion slot cover by unscrewing slot cover screw. Keep the
screw for later use.
5. Pick up your CMI8330 by its top edge. Firmly slide the CMI8330 into the
slot. AnchortheCMI8330's mountingbracket with the screwyou kept from
step 4.
6. Put the computer cover back on and reconnect the power cords.
Note: At step 5, if the CMI8330 will not slide in smoothly, do not force it.
Make sure the CMI8330 is lined up properly, and try again. You may need
to loosen the adjacent slot's rear cover to make the CMI8330 fit properly.

P.S.: We set default SB mixer emulation functions to disable. It fits to
almost applications and GAME. If there is any applications using SB
panningfunctions to separate left and right sound channel, you can set this
functions to enable.
3.4 CMTEST
CMTEST.EXE checks the CMI8330 I/O address, IRQ channel, DMA
channel, and tests the CMI8330 hardware functionalityincluding synthesized
music, voice playback and voice recording. At DOS prompt, type
CMTEST [Enter]
Hardware/Software Section 3- Utilities Software

Media Rack System Mixer

CMTEST scans I/O address, IRQ channel and DMA channel jumper settings
on the CMI8330.
After I/O settings are tested, you may proceed to choose to test synthesized
music, output voice and test recording functions. Speakers connected to the
CMI8330 are necessary for all the tests. Microphone is necessary for test
recording.
Synthesized music test generates music output with the CMI8330 on board
synthesizer. Output voice test generates voice with the CMI8330 digitized
output channel.Fortest recording,you need to speak to the microphone. Your
speech will be reproduced on the digitized output channel.
If you can't hear sound during any of the above tests, check connections
between the CMI8330 and speakers, microphone then run the test again.
If your CMI8330 passes these tests, it is OK for your applications.
According the CMTEST shows the I/O address, IRQ and DMA information’s,
please add the follow setting to your AUTOEXEC.BAT file.
SET BLASTER=A220 I7 D1
Note: A#.......# is the I/O address
I#.........# is the IRQ number
D#.......# is the DAM channel
This settinginAUTOEXEC.BATwill behelpful to some softwares torecognize the
CMI8330.
3.5 CMUTIL
CMUTIL.EXE is an integrated voice utility programto help you create and
replay voice files. At DOS prompt, type CMUTIL [Enter]
Integrated environment of CMUTIL appears on screen.
Play voice from disk: Play disk file (.VOC) contents.
Use arrow key to highlight and press Enter to activate. You will see the same
pop up menu as in LOADcommand. You can select a file thesame way you do
as in LOAD command. You will hear the sound that is stored in the selected
file in digitized form.
