for Philips PCA761AW Audio Card
Version 1.0P 08/27/96
This file is divided into two major parts:
1) Configuring Your Audio Card
2) Using Your Audio Card
The first part deals with making changes to your card configuration
to make your audio card work properly and desirably. The second
part describes how to use the utilities created from the software
installation process.
PART 1. CONFIGURING YOUR AUDIO CARD
-----------------------------------
1.1 Changing Resource Assignments & Enabling/Disabling Game Port
To change the card's resource assignments and enable/disable its
game port in DOS and Windows 3.xx, type "CONFIG" at the C:\PCA761AW>
prompt (or at the prompt of the custom directory where you installed
the PCA761AW program files) to evoke the DOS-based PCA761AW
configuration utility. This configuration utility is basically a
transformation of the installation program described in Section
3.1.2 of the <<Installation Guide>>. Please refer to that section
for specific instructions on using the utility.
DO NOT randomly change the card's resource assignments. Your audio
card cannot share the same I/Os, IRQs or DMAs with any other
peripheral device in your system. Change the resource assignments
ONLY IF you know any of the card's I/O, IRQ and DMA settings
is already in use by another device in your system. When making
changes, make sure that no other device is using the new settings
that you are assigning to the audio card.
NOTE: In case of a resource conflict, you can either change the
card's resource assignment or the conflicting device's
resource assignment.
Keep all the physical and logical components of the audio card
enabled at all times. The only exception is the card's game port.
The game port uses 201 as its I/O base, which is not changeable. If
you do not have a joystick or a MIDI instrument (e.g., a MIDI
keyboard) connected to the GAMEPORT/JOYSTICK connector on the card,
you may disable the game port to avoid a potential I/O conflict with
the other devices.
After closing the configuration utility, reboot your PC to put changes
into effect. All the changes remain effective until the next time you
change them.
1.2 Changing DMA Buffer Sizes and Saving Mixer Settings
Your audio card supports simultaneous recording and playback from all
sources. This full-duplex feature requires two DMA channels,
determined by the Primary DMA and Secondary DMA values which you set
for the "PCA761AW Music" on the "Custom Configuration" panel of the
Installation and Configuration Utility (see Section 1.1 above).
Corresponding to the DMA channels are a "play buffer" and a "record
buffer". The sizes of these two buffers determine the unit data
volumes transferred bi-directionally between memory and your audio
card at one time. The larger the buffer sizes, the faster the
transfers, but the larger the memory consumption.
Once you have determined an ideal set of mixer settings (see Section
2.2.1 below), you can save these settings as defaults, so that you
do not need to spend time on making these settings every time you
enter the mixer panel.
If you are a Windows 3.xx user, perform the following steps to change
the DMA buffer sizes or save the mixer settings:
1. Enter Windows
2. Double click the "Control Panel" icon in the "Main" group.
3. Double click the "Drivers" icon in the "Control Panel" window.
4. Double click the "InterWave Audio Driver" in the "Installed
Drivers" list of the "Drivers" dialog box that appears. The
"PCA761AW Driver Setup" dialog box appears.
5. Increase or decrease the play buffer size by overwriting the
original value.
6. Increase or decrease the record buffer size in the same manner.
7. Mark or unmark the "Save Mixer Settings on Exit" check box as
desired.
8. Click on the "Restore Defaults" button if you want to restore
the settings in this dialog box to the factory defaults.
9. Click on the "OK" button to close this dialog box. Changes
will take effect the next time when you start Windows.
NOTE: The "Save Mixer Settings on Exit" setting can also be made on
the mixer panel (see Section 2.2.1).
If you are a Windows 95 user, perform the following steps to change
the DMA buffer sizes or save the Mixer settings:
1. Start Windows 95.
2. Click on the "Start" button on the desktop and select
"Settings" and "Control Panel".
3. Double click the "Multimedia" icon at the "Control Panel"
window that appears.
4. Click on the "Advanced" tab of the "Multimedia Properties"
folder that appears.
5. Double click the "Audio Devices" category.
6. Double click the "Audio for PCA761AW Device Driver" dialog
box to display the "Audio for PCA761AW Device Driver
Properties" window.
7. Click on the "Settings" button.
The "PCA761AW Driver Setup" dialog box appears.
8. Increase or decrease the play buffer size by overwriting the
original value.
9. Increase or decrease the record buffer size in the same manner.
10. Mark or unmark the "Save Mixer Settings on Exit" check box as
desired.
11. Click on the "Restore Defaults" button if you want to restore
the settings in this dialog box to the factory defaults.
12. Click on the "OK" button to close this dialog box. Changes
will take effect the next time when you start Windows.
NOTE: The "Save Mixer Settings on Exit" setting can also be made on
the mixer panel (see Section 2.2.1).
1.3 Switching between Built-in Wavetable Synthesizer & External
MIDI Instrument
Your audio card only allows one MIDI source to be active at any
moment of time: either the card's built-in synthesizer or the external
MIDI device connected to the card's GAMEPORT/MIDI connector. By
factory default, the built-in synthesizer, which is used to play back
MIDI files from one of your drives, is set as the active source. If
instead you want the audio card to play MIDI music generated from the
connected MIDI device (e.g., a MIDI keyboard), you must change this
factory default.
NOTE: To use an external MIDI device, the audio card's game port must
also be enabled in the "Custom Configuration" panel. For
details about the "Custom Configuration" panel, see Section
3.1.2 in the <<Installation Guide>> or see the earlier Section
1.1 in this file.
If you are a Windows 3.1 user, perform the following steps to switch
between the two sources:
1. Enter Windows.
2. Double click the "Control Panel" icon in the "Main" group.
3. Double click the "MIDI Mapper" icon in the Control Panel to
display the "MIDI Mapper" dialog box.
4. Select "InterWave Synth" to use the built-in wavetable
synthesizer or select "InterWave UART" to use the external
MIDI device.
5. Click on the "Close" button to exit the dialog box.
If you are a Windows 95 user, perform the following steps to switch
between the two sources:
1. Click on the "Start" button and select "Settings" and "Control
Panel".
2. Double click the "Multimedia" icon in the "Control Panel" to
display the "Multimedia Properties" folder.
3. Click on the "MIDI" tab and select "PCA761AW MIDI Synth" to
use the built-in wavetable synthesizer or select "General MIDI
Instrument" to use the external MIDI device.
4. Press the "OK" button to exit the "Multimedia Properties"
folder.
PART 2. USING YOUR AUDIO CARD
-----------------------------
Now, all kinds of funs are there waiting for you. You can cheer your
work spirits with Windows' sound effects, play your audio CDs while
you work, feel the thrills of playing a 3D game, mix different kinds
of music and sounds for fun or for work, compose a musical piece on
your own... You just need appropriate software to get what you want.
If you are a beginner user and do not know where to start, try
Windows' Media Player, Sound Recorder (in the "Accessories" group of
Windows 3.xx and the "Multimedia" menu of Windows 95) or CD Player
(Windows 95 only) first. Also, playing sounds from an output device
connected to the audio card does not require any software, as long as
this device comes with its own controls. For example, you can play
audio CDs from your CD-ROM drive by pressing its play/stop button.
Because of an audio card's application varieties, the follow sections
focuses on how to use the PCA761AW utilities while leaving the
application details to your application software's documentation.
2.1 DOS-based Mixer Utility TESTMIX.EXE
Type TESTMIX at any DOS prompt to enter the mixer panel.
Use your mouse or keyboard to make the selections and settings. To
use your mouse in DOS, you must have your mouse driver for DOS
installed. Refer to your mouse manual for instructions. To use the
keyboard, follow these hot key definitions:
Use To
<TAB> Move across buttons
<Up & down arrow keys> Increase/decrease a scroll bar volume
setting
<Space Bar> Mute/unmute a source
<Enter> or <highlighted key> Execute the selected push button
Following is a description of the mixer panel elements:
Scroll Bars
MIDI Sets the output level of the MIDI music that is being
played
WAVE Sets the output level of the .WAV file that is being
played
CD Sets the output level of the audio CD title that is being
played.
LINE IN Sets the output level of the sounds or music playing from
the device connected to the card's LINE IN connector.
MIC Sets the output level of the voices or sounds coming from
the microphone connected to the card's MIC jack.
MASTER Sets the overall output level.
NOTE: If you are using the keyboard to set a volume level. Tab to the
mute/unmute button (see below) below that scroll bar first.
Then use the up and down arrow keys to set the volume.
Mute/Unmute Buttons (under the scroll bars)
suppress or release the output from the corresponding sources.
When a mute/unmute button carries an "X", the corresponding
source is muted.
Push Buttons

WAVE Test Plays the test WAVE file TESTWAVE.WAV
Stop Test Stops the MIDI or WAVE file which is being played
Set Default Restores the factory default mixer settings
Save Saves the current mixer settings
Exit Exits the TESTMIX.EXE program
New settings will take effect only when you close the mixer panel and
reenter the previously run audio application. All the changes remain
effective until the next time you change them.
2.2 Windows-based Applets
A PCA761AW Mixer applet is provided for both Windows 3.xx and
Windows 95 users. In addition, Windows 95 users also get a Volume
Control applet and an uninstall utility after the driver
installation. Windows 95 constructs the Volume Control applet by
referencing the PCA761AW driver information.
2.2.1 The PCA761AW Mixer Applet
Double click the "Mixer" icon in the "Philips PCA761AW" program
folder or program group to display the mixer panel. Following is a
description of the panel elements:
Menu Bar Menus
The File Menu
Select the "Exit" command to close and exit the mixer
panel. This is the same as double clicking the control
menu box at the upper left corner of the mixer panel.
The Options Menu
Select or deselect the "Save on Exit" command to determine
whether the latest mixer settings made in the current
session should be saved before exiting the mixer panel.
The selection and deselection can also be done in the
"PCA761AW Driver Setup" dialog box (see Section 1.2).
The View Menu
Select "Basic View" to display the mixer panel in its
basic view. Select "Advanced View" to display the mixer
panel in its advanced view. The advanced view offers
more panel elements for selection and adjustments.

output from the corresponding sources. When a Mute/Unmute button
carries an "X", the corresponding source is muted.
2.2.2 The Volume Control Applet (for Windows 95 only)
Windows 95 creates the Volume Control applet based on the PCA761AW
driver information. Basically, this applet is very much the same
as the PCA761AW Mixer both in terms of functions and looks.
There are two ways to access the Volume Control applet:
* Double click the loudspeaker icon at the lower right corner of
the taskbar on the desktop.
NOTE: You must mark the "Show volume control on the taskbar"
check box on the "Audio" folder page of the "Multimedia
Properties" folder (accessible through the "Multimedia"
icon in the "Control Panel" to have the loudspeaker icon
displayed on the taskbar. If the Volume Control applet
is indicated not installed when marking the check box,
go to "Control Panel", select "Add/Remove Programs",
"Windows Setup", "Multimedia" and "Volume Control" and
follow the screen instructions to install it.
* Click on the "Start" button on the taskbar and select
"Programs", "Accessories", "Multimedia", and "Volume Control".
NOTE: You must install the Volume Control applet to have it
display in the "Multimedia" menu. If it is not displayed,
follow the note text above to install this applet.
For information on using the Volume Control applet, please refer to
the Help Topics in the Volume Control's Help menu.
2.2.3. The Uninstall Utility (for Windows 95 only)
The uninstall utility removes the program files, program folders and
icons, as well as any system file entries related to the PCA761AW
audio card. Unless you are replacing this audio card with another
audio card, you are not recommended to use the uninstall utility.
To use this utility, double click the "Uninstall" icon in the
"Philips PCA761AW" program folder, answer Yes to a confirmation
request and restart Windows 95 to complete the uninstallation.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
