1. Line Inputs. This pair of RCA jacks receives stereo line-level audio from
the outside world. Both inputs are high-impedance and are designed for
use at -10dBV nominal levels. They can handle peak signals of up to
+6dBV (2 Vrms). Typical connections to these jacks are line-level outputs
of a mixer or external microphone preamp, the recording outs of an instru-
ment amplifier or the line outs of a tape deck.
NOTE: The Line Inputs are not designed for direct connection to micro-
phones. In order to use a microphone with the DMAN PCI, you will need to
connect it through either a microphone preamp (such as the Midiman
“Audio Buddy”) or a mixer (such as the Midiman “MiXiM 10”).
2. Line Outputs. This pair of RCA jacks outputs stereo line-level audio to the
outside world. The output signals are designed for -10dBV nominal levels,
with peak output of up to +6dBV (2 Vrms). Normally these jacks would be
connected to an external amplifier and speakers, self-powered multimedia
speakers, a DAT or other stereo mix-down recorder.
3. MIDI Interface Connector. This connector attaches to the included MIDI
Interface Cable to provide standard MIDI Input and Output connectors

5.

(known as “5-pin DIN” connectors). Functionally, the MIDI Interface oper-
ates as a standard MPU-401 “UART mode” MIDI interface.
4. CD-ROM Headers. This pair of headers accepts line-level audio from a
CD-ROM player or other source internal to the computer. The two headers
are wired in parallel and their different formats will accommodate most
CD-ROM audio outputs. Only one header should be used at a time – the
other should not be connected to anything.
5. MIDI Daughterboard Header. This is a standard format header that
accepts third party MIDI synthesizer daughterboards. Both MIDI and
audio streams traverse this header. The daughterboard MIDI is shared by
the MIDI Interface Cable’s MIDI Out.

Quick Guide to Getting Started
Here is the list of steps required to get your DMAN PCI card up and running:
1. Install drivers and support software (See Windows Software Installation).
IMPORTANT: You should run the DMAN PCI Setup program before
installing the DMAN PCI adaptor card in your system. This order will make
Plug-and-Play configuration more reliable.
2. Physically install the card in your computer (See Hardware Installation).
3. Restart Windows and allow Windows Plug-and-Play to configure the
DMAN PCI drivers (See Restarting Your Computer for the First Time).
4. Configure your digital recording software to select the DMAN PCI as its
active audio adaptor (See Using DMAN PCI with Software Applications
and your applications software manual).
Windows Software Installation
Your DMAN PCI package includes a set of Windows 95/98 software diskettes.
These diskettes contain the DMAN PCI Setup program, the DMAN PCI
Windows driver software and DirectX software drivers. This section describes
how to run the Setup program and install all of these DMAN PCI software
components.
IMPORTANT: You should run the DMAN PCI Setup program before
installing the DMAN PCI adaptor card in your system. This order will make
Plug-and-Play configuration more reliable.
Follow the directions below to run the DMAN PCI Setup program:
1. Insert the disk entitled “DMAN PCI Windows Driver & DirectX
Installation, Disk 1” into your 3.5 floppy drive. Go to the Start menu; select
"Run…"
2. Type "a:\setup" and click OK (use “b:\setup” if you must use the B: drive).
3. The Midiman DMAN PCI logo will appear while InstallShield prepares for
setup. Then, the big blue DMAN PCI Windows Setup screen appears,
announcing “Midiman DMAN PCI Setup.”
4. A Welcome dialog box now appears. Select "Next>" to continue.
5. The Select Components dialog box then appears. The list of installable
components will show: Driver Files and DirectX Files. Each component
will have a check box to the left of it, which indicates whether or not that
component will be installed. By default, each component is selected for
installation. It is recommended that you leave the selections this way.
7

IMPORTANT: The DMAN PCI requires the installation of DirectX drivers,
version 5 or higher. Without DirectX installed, the DMAN PCI driver instal-
lation may crash. The DMAN PCI Setup program can install DirectX 6 on
your computer before the DMAN PCI drivers are installed. It is very impor-
tant to select this option if you do not already have DirectX 5 or higher
installed on your computer.
Also in the Select Components dialog box is the Destination Folder setting.
This specifies where the selected software components will be stored. By
default, this folder is C:\MIDIMAN\DMAN PCI. It is recommended that you
leave that setting as is.
NOTE: You may select another target folder by selecting the Browse... but-
ton. If you do choose this option, be sure to write down the destination fold-
er, as you will need this information later in the installation process.
6. Select “Next>” to copy the driver files to the destination folder. This copy
process may require a few minutes. Since the software requires several
diskettes, Setup will occasionally prompt you for the next diskette. When
prompted, remove the previous diskette, insert the new one, and select
“OK” (no need to browse or type a path other than [drive letter]:\ ).
Continue to do this until all the components have been copied to your hard
disk.
7. If you have selected the DirectX component for installation as suggested,
setup will now run the DirectX installer. When the Microsoft DirectX 6
Setup dialog box appears, select “Yes” to begin installation.
NOTE: The DirectX 6 installer is smart enough to not overwrite newer ver-
sion(s) of DirectX that may already be installed on your system.
8. The Microsoft DirectX 6 Setup will display a Licensing Agreement. To
agree, press "Yes." Setup will continue its check for versions of DirectX,
then extract and copy the necessary files.
9. A DirectX Setup dialog box appears when it completes the installation suc-
cessfully, and it will ask you to select “OK.” Click on “OK”.
10. Next, the Information dialog box tells you that Setup will now install the
drivers and update registry. It may take up to a few minutes. Click “OK,”
and wait for the Setup Complete dialog box to appear.
11. When the Setup Complete dialog box appears, setup is complete. It is rec-
ommended that you shut down your computer and then install the DMAN
PCI card. To do this, select “No, I will restart my computer later,” then
click “Finish”. This will return you to the Windows Desktop. You can
remove the last floppy disk at this point. Go to the Start button, choose
“Shut Down,” then tell the computer you want it to “Shut down,” and
click OK.

Hardware Installation
After successfully installing all of the DMAN PCI software components (See
Windows Software Installation) and powering down your computer, you may
install the DMAN PCI adaptor card.
Installing the Adaptor Card
To mechanically install the DMAN PCI, do the following:
1. Turn off your computer.
2. Remove its cover and position the computer so you may easily access its
PCI slots.
3. Select the PCI slot where you will install your DMAN PCI card. Make sure
it is a PCI slot. If you don't know what “PCI slot” means, check the
owner’s manual for your computer. PCI slots are distinguishable from ISA
slots by being shorter and set back farther from the outside of the comput-
er. However, some newer computers have only PCI slots.
4. The PCI slot you just selected should have a metal bracket associated with
it that covers the PCI slot’s access hole on the back of the computer. This
bracket is usually fastened to the computer with a single screw. Remove
the screw and bracket -- be sure not to lose the screw as you will need it
later!
5. Before removing the DMAN PCI from its protective anti-static bag, touch
the metal power supply case of the computer in order to dissipate any stat-
ic electricity charge your body may have accumulated.
6. Remove the DMAN PCI card from its bag. If you are planning on
installing an optional daughterboard, now is the time to do it (see
Installing a Daughterboard below). If you will be connecting your com-
puter’s CD-ROM audio outputs to the DMAN PCI, it might also be a good
time to do this.
7. Position the DMAN PCI card over the target PCI slot and fit the card loose-
ly over it with the DMAN PCI card upright. Press the card gently but firm-
ly downward into the slot until the card is completely and squarely seated
in the slot. If the card seems difficult to seat, a slight rocking motion may
help. If the card is impossible to seat, you may be trying to install the
DMAN PCI in a non-PCI slot. If this is the case, go back to Step 3.
8. Once the DMAN PCI board is firmly seated, screw its metal bracket down
into the computer chassis, using the screw you removed in Step 4 above.
9. Place the cover back on your computer.
9

Installing a Daughterboard
The DMAN PCI comes with a built-in General MIDI compatible wavetable
synthesizer. However, a (26-pin header) daughterboard connector is provided
for installation of an optional third-party synthesizer daughterboard. The
daughterboard header is compatible with most industry-standard daughter-
boards.
To install a daughterboard on the DMAN PCI daughterboard header, follow
these steps:
1. With the DMAN PCI in front of you, remove the daughterboard from its
anti-static bag.
2. Carefully align the daughterboard header socket with the DMAN PCI
header pins. Make sure that the daughterboard is properly oriented so it is
“inboard” to the DMAN PCI card.
IMPORTANT: Pin 1 of the header is marked on the DMAN PCI in white
ink. Be sure that DMAN PCI pin 1 will match up with the daughterboard
pin 1 when installed.
3. Press the daughterboard and DMAN PCI together until the header and
socket mate firmly.
Connecting to External Devices
Once the DMAN PCI card is installed in your computer, you are ready to make
connections to external devices. While reading this section, please refer to the
diagram “Typical DMAN PCI Setup.”
1. Connect the DMAN PCI Line Out jacks to your amplifier, multimedia
speakers, the channel or monitor inputs of your mixer, or whatever else
you may be using to listen with. To avoid a potential audio “pop” it is a
good idea to turn off the amplifier or self-powered speakers before con-
necting to Line Out.
2. Connect the buss, aux, direct, or alt out of your mixer, or Line Out of
another audio source, to the DMAN PCI Line In jacks. In order to use a
microphone with the DMAN PCI, the microphone must be connected to
the DMAN PCI through a mic preamp or mixer.
3. If you plan on using external MIDI, connect the supplied MIDI Interface
Cable to the matching DMAN PCI connector at the back of the computer.
Use the cable assembly thumbscrews to attach it securely to the DMAN
PCI connector.
10

4. If you installed the MIDI Interface Cable in Step 3, you may now attach
any MIDI devices you may have. Connect the MIDI device MIDI Out to
the DMAN PCI MIDI In, and connect the MIDI device MIDI In to the
DMAN PCI MIDI Out. You will most likely need to use standard MIDI
cables to make these connections.
5. Move your computer back to its original position. You may now turn on
your computer.
Typical DMAN PCI Setup
Restarting Your Computer for the First Time
(after installing the DMAN PCI)
After installing the DMAN-PCI board, the first time you power up your com-
puter the Plug-and-Play (PnP) system must configure the board for use. This
process will usually only be required once, unless you move the DMAN-PCI to
a different PCI slot at a later time.

In Windows 98
1. After carefully following the “Hardware Installation” instructions, you
may power up your computer (A Building driver information database
box will appear and then go away).
2. The Add New Hardware Wizard box will ask you “What do you want
Windows to do?” “Search for the best driver for your device” will already
be checked. Click “Next>.”
3. The Add New Hardware Wizard instructs Windows to search for new dri-
vers. Uncheck “floppy drive,” and check the box that says, “Specify a loca-
tion.” The A:\ drive will be highlighted as the search destination. It is
IMPORTANT here that the folder that was created for the DMAN-PCI dri-
ver during the “Windows Software Installation” be used instead. Please
replace “A:\” by typing in the following path, exactly as shown:
C:\Midiman\DMAN-PCI
NOTE: If for some reason you selected another destination folder during
software installation, please enter it instead.
4. Click “Next>.” Windows driver file search will find the driver for the
device: “DMAN-PCI Audio Accelerator.” Click Next>, and Windows will
copy files.
5. The Add New Hardware Wizard will announce that Windows has finished
installing the software required. Click “Next>.”
6. A New Hardware Found box will appear while Windows associates the
drivers with the device. When it returns you to your Windows desktop,
the DMAN PCI is now ready for use.
In Windows 95
1. After carefully following the “Hardware Installation” instructions, you
may power up your computer (A Building driver information database box
will appear and then go away).
2. A New Hardware Found dialog box appears, asking you how you want to
select your new driver. Select “Driver from disk provided by hardware
manufacturer” will be checked at this point. Click OK.
3. An Install From Disk dialog box now appears, and the A:\ drive will be
highlighted as the search destination. It is IMPORTANT here that the fold-
er that was created for the DMAN-PCI driver during the “Windows
Software Installation” be used instead. Please replace “A:\” by typing in
the following path, exactly as shown:
C:\Midiman\DMAN-PCI
NOTE: If for some reason you selected another destination folder during
software installation, please enter it instead.
12

4. Click OK. This will install the DMAN-PCI drivers to their proper locations
within the system.
5. A System Settings Change box now shows up, asking if you want to
restart your computer to finish setting up the new hardware. Click “Yes.”
6. Reboot your system if asked. Your DMAN-PCI is now ready for use.
Windows Driver Configuration
In most cases, the DMAN PCI will install without a hitch. However, it is some-
times possible for PnP to run out of resources and a resource conflict will
result. This section focuses on driver configuration and also the elimination of
resource conflicts.
The SoundFusion Control Panel Applet
The DMAN PCI software installation places the SoundFusion properties page
in the Windows Control Panel. This properties page is used for specialized
configuration of the Crystal SoundFusion DSP onboard the DMAN PCI. You
may open the SoundFusion properties page by selecting Settings | Control
Panel | SoundFusion from the Windows Start menu.
There are three tabs in the properties page: General Properties, AEC, and
MIDI. General Properties controls the following settings:
• 3D Stereo Enhancement. Enabling this feature will increase the apparent
left/right channel separation of the outgoing audio. This “enhancement”
adds a large amount of coloration to the audio and may or may not be
what you desire for your use. This is disabled by default to avoid any
potential confusion.
13

• SoundFusion™ DSound Acceleration. This feature allows the DSP to per-
form many of the audio duties that would otherwise have to be handled by
the host CPU. In other words, it enables audio acceleration. The default
setting is “enabled.”
• Taskbar. Enabling this function places a SoundFusion™ icon on the
Windows taskbar for easy access to the SoundFusion properties page.
The AEC page controls the following setting:
• Acoustic Echo Cancellation. This feature could be used if the DMAN PCI
board is being used as a speakerphone. This is disabled by default (set to
Never).
The MIDI page controls the following setting:
• Maximum Notes. This is the polyphony setting of the built-in synthesizer.
Raising this number will increase the number of simultaneous MIDI notes,
but will decrease the number of simultaneous 3D audio channels. By
default, this is set to the General MIDI standard setting: 24 notes simulta-
neously. 64 notes is the maximum polyphony possible.
The Windows Device Manager
You may find the DMAN PCI driver status in the Windows Device Manager
page of the System Properties dialog box. Open the Device Manager by press-
ing the Windows Start Button and selecting Settings | Control Panel | System |
Device Manager. Once the Device Manager is open, it will display a list of
device “types.” Scroll down through the list until you locate Sound, video and
game controllers. Click on the “+” next to Sound, video and game controllers
to view the installed products within that type. DMAN PCI is of the class
Sound, video and game controllers and should appear in the list if the DMAN
PCI drivers are properly installed. Below is an example view of the Device
Manager device list.
14

This example shows the Midiman DMAN PCI and Midiman WINMAN 4x4/S
(another Midiman product) entries in the Windows Device Manager device
list. The DMAN PCI is properly installed with no conflicts, as is the WINMAN
4x4/S.
If a device in this list is having a resource conflict with another device, or if
there are driver problems, a yellow exclamation point will generally appear on
top of the icon next to that device. There are several approaches to solving this
dilemma.
NOTE: Most sound card installation problems result from attempting to use
system resources (IRQ’s and Address locations) that are already in use by other
hardware components in the system.
Driver Resource Conflicts
By highlighting the item with the problem (yellow exclamation point show-
ing), then clicking the Properties button (or double-clicking the actual item),
you will open up a Properties page for that device. Selecting the Resources tab
from within the Properties dialog box will allow you to view resources, plus
view possible conflicts by highlighting each item (by clicking on it) one-by-one
and examining the “Conflicting resource list:” at the bottom of the box.
It is sometimes possible for a resource problem to not show up in the
Conflicting Resource List or as a yellow exclamation point in the Device
Manager. If you have any doubts about the configuration of your device (or
just to double-check), you can view all of the devices and their associated IRQs
by highlighting Computer at the top of the Device Manager list and clicking
the Properties button. This will give you a dialog box with IRQ numbers on
the left, and devices on the right.
15

If PnP has chosen an IRQ for the DMAN PCI that is being shared with another
device, there might be a device conflict. If the DMAN PCI is sharing an IRQ
with an entry named “IRQ Holder for PCI Steering,” that is normal and should
function properly. If the DMAN PCI is sharing an IRQ with another PCI
device (such as a USB Host Controller), it might also do so without problems
since the DMAN PCI is capable of sharing an IRQ with many other PCI prod-
ucts. However, IRQ’s are rarely shareable between ISA devices that are not
PnP-compliant and other cards. If this is the case one of the devices will have
to be manually adjusted to use another IRQ.
NOTE: When resolving conflicts between PnP and non-PnP devices, it is
usually easier to readjust the resource settings of the non-PnP device.
Windows is only aware of the resource settings of the installed PnP devices
and has no information available to it for adjusting the PnP devices around
the non-PnP devices. The exception to this is when a non-PnP device has a
true Windows 98/95 driver written for it, or if the BIOS allows instructions
for an IRQ to receive a legacy device as opposed to a PnP device. In that case
Windows is aware of the non-PnP device’s resource requirements.
If you ever need to change the DMAN PCI card’s IRQ, the easiest way is to
move the DMAN PCI to another available PCI slot. This will cause the system
to recognize it again as new hardware and establish it with another IRQ. Some
newer BIOS’s (see your computer manual) allow the selection of an IRQ for
each PCI slot on the motherboard. This can be very handy in resolving IRQ
assignments for PCI devices. However, if there are no IRQs available, some
kind of reconfiguring or reprioritizing your system may be required. See the
“Troubleshooting” guide for more info. Also, a second hardware configuration
can be created for running two sets of hardware profiles. See your Windows
documentation for help in this area.
As mentioned earlier, the Computer Properties list is the best source of infor-
mation to establish availability of resources. Clicking the Input/Output (I/O)
button at the top of the box will give you a list of Addresses in use (as well as
DMA channels, although none are used by the DMAN PCI). Usually, there are
not address conflicts between PnP devices, but one might note that an address
of 300h (the default address of the WINMAN 4x4/S, for instance), will read
“0300” in this list (it is a 16-bit hexadecimal representation).
16

Using DMAN PCI with Software Applications
Once the DMAN PCI software is set up, the card is installed, and its drivers are
properly loaded, it is ready for use with audio application software. Some of
these applications will require manual configuration in order to use the DMAN
PCI. There are a few audio applications built into Windows that will be com-
mon on all PC systems: usually a mixer, sound recorder and media player.
Most users may choose to purchase and install third-party software packages
that are much more powerful than those provided with Windows.
Either way, it is important to understand the name and purpose of each
DMAN PCI function.
The Various DMAN PCI Windows Devices
Since the DMAN PCI is a multi-function board, it appears to Windows soft-
ware as a collection of different Windows devices:
• DMAN PCI Audio
• DMAN PCI Mixer
• DMAN PCI Synth
• DMAN PCI External MIDI
Whenever you configure a Windows-supplied or third-party software applica-
tion to use the DMAN PCI, you will need to look for these devices. The
“DMAN PCI Audio” device is responsible for audio recording and playback,
such as that contained in WAV files. The “DMAN PCI Mixer” sets the record-
ing and playback levels of the various audio sources on the DMAN PCI board.
The “DMAN PCI Synth” is the General MIDI synthesizer that is built into the
DMAN PCI board. Windows sees it as a MIDI Output device. The “DMAN
PCI External MIDI” device is associated with the MIDI In and MIDI Out jacks
on the MIDI Interface Cable, and with MIDI going to and coming from the
optional MIDI daughterboard.
NOTE: The “DMAN PCI Synth” device is dedicated to the built-in synthesizer.
The “DMAN PCI External MIDI” device is shared between the daughterboard
and the external MIDI connector. In other words, whatever MIDI data you
send to the external MIDI connector will also go to the daughterboard; the
built-in synthesizer is independent of the other two.
The Windows Mixer (WSS Mixer)
The DMAN PCI audio playback and recording mixes are handled by the
Windows Sound System mixer, which ships with Windows. There are two
ways to open this mixer:
17

1. At the Windows Start menu select Programs | Accessories | Multimedia |
Volume Control.
2. Double-click your mouse on the little “speaker” icon on the Windows
taskbar. If this speaker icon is not present on your taskbar, you may enable
it by selecting Settings | Control Panel | Multimedia from the Windows Start
menu, checking “Show volume control on the taskbar” and clicking the
“OK” button.
Once open, you may view and adjust the Master (playback) mixer and the
Record mixer.
Windows “Master” (Playback) Mixer
The Master mixer is the default mixer and appears each time you open the
Windows volume control. The Master mixer provides control over the play-
back volume and balance for each DMAN PCI audio source:
• Master – This is the board’s master volume/balance; it controls the overall
level at the board’s Line Out jack.
• Wave – This sets the output level/balance from the board’s D/A converter.
• Synthesis – This sets the output level/balance of the onboard synthesizer.
• DaughterBd – This sets the output level/balance of the daughterboard syn-
thesizer if a daughterboard is installed.
• Compact Disc – This sets the output level/balance of the audio coming
from your CD-ROM, if connected to the board.
• Line In – This sets the output level/balance of the Line Input. This control
may be used to monitor the Line In signal during full-duplex
recording/playback.
To adjust volume levels and balances, simply click and drag the desired con-
trols with your mouse. Note that each device also has a “Mute” control. When
18

Mute is selected, it will completely override the volume and balance settings
for that channel. When Mute is not active, the volume and balance settings are
restored.
NOTE: When the drivers are first installed, the Daughterboard and CD-
ROM channels of the mixer are muted by default. This is to prevent any
excess noise from entering the DMAN PCI if either or both of those devices
are not installed/connected. If you install either device, make sure you
unmute them in the mixer or you will not hear them.
IMPORTANT: The inside of the computer is a very noisy place and noise
from other computer components may leak into any audio sound card. For
best signal-to-noise performance, mute or turn down the playback volume
levels of any devices not currently in use. Multimedia-grade CD-ROM dri-
ves are notoriously noisy and so are inputs that have nothing connected to
them (such as an unused daughterboard connector or Line In). We recom-
mend muting each of these when not being used.
WSS Properties Page
The Windows mixer is configured and customized via its property page. To
access this page, select Options | Properties from the mixer’s menu. The proper-
ty page will immediately appear.
The properties page provides three settings:
1. Mixer Device. This selects which audio card will be controlled by the
Windows mixer. If the DMAN PCI is the only audio card installed in you
system, it will probably be your only choice.
2. “Adjust volume for.” This selects whether the Master Playback or Record
mixer will be displayed.
3. “Show the following volume controls.” This lets you select which audio
19

devices to display in the mixer. If a device’s box is checked, it will appear
in the mixer. You can completely customize the look of your mixer by
unchecking any device that you do not plan to currently use.
Windows “Record” Mixer
The Record mixer selects the recording source and provides control over the
recording volume and balance for each DMAN PCI audio device. Since the
Windows Mixer always starts up with the Master mixer showing, you will
need to manually select the Record mixer in order to view it. Do this by select-
ing Options | Properties from the Master mixer. A dialog box will appear, and
you may then select “Recording” from the box labeled “Adjust volume for.”
See the section “Windows Mixer Properties Page” for more information about
this dialog box.
The Record mixer allows you to select one input at a time for recording. This is
accomplished by checking the “Select” box below the desired device. A special
device named “Loopback” allows you to record from all sources simultaneous-
ly.
In this example, the Line In has been chosen as the input device. This is the
default setting when the drivers are first installed. To adjust recording levels
and balances, simply click and drag the desired controls with your mouse.
Windows Sound Recorder
Windows provides a mechanism for audio playback and recording using its
Sound Recorder application. Open the Start Menu, then select Programs |
Accessories | Multimedia | Sound Recorder to bring up the Sound Recorder. The
Sound Recorder relies on the Windows multimedia settings to tell it what
devices to record and play back. Access these settings in the Multimedia
Properties Audio page (found in Settings | Control Panel | Multimedia | Audio).
In this property page, be sure to select “DMAN PCI Audio” as the preferred
playback device and preferred recording device. You might also want to select
“Use only preferred devices” as well. You will also need to open the Windows
