`SBP-SET & SBP-MIX
`
`Two program are provided to control and select input sources and
`volume levels.
`
`D SBP-MIX
`
`this is a memory resident program for setting Volume
`controls of the Sound Blaster Pro.
`
`I SBP-SET
`
`this program controls the selection of sources, filters
`and volume from the DOS command line.
`
`Mixer Control
`
`The Sound Blaster Pro mixer lets you control the volume of the
`following:
`
`I Master—the overall volume of each source.
`
`Voice—the digitized sound volume.
`
`FM Music—the synthesized music volume.
`
`CD—the Compact Disk volume
`Line-In—the Audio Line-In volume
`
`To install the program into memory:
`
`1. Type SBP-MIX and press Enter.
`
`2. To activate the installed SBP-MIX press ALT key and then the 1 key.
`
`5. To remove the program from the memory type SBP-MIX/u.
`
`Changing the Hot-Key
`
`The default hot-key to activate SBP-MIX is Alt 1. You can change the
`hot-key by entering the forrnat:SBP—MlX [/khotkey]. The parameter
`/k specifies the new hot-key. A hot-key consists of a shift status key and
`a number key on the main keyboard.

`
`D
`
`SHIF'I'L—left shift key
`
`SHIFTR—right shift key
`
`D ALT——alternate key
`
`D CTRL—control key
`
`The number key is the number key from 1 to 9 on the main keyboard.
`
`Fro example, to specify the control key and 9 as the new hot-key, type
`SBP-MIX /RCTRL9.
`
`SBP-MIX Menu
`
`When you press the hot~key, SBP—MIX will pop-up at the DOS prompt
`or from any program.
`
`Note: SBP-MIX will not pop-up from programs that take over the
`keyboard interrupt. In case this happens, you need to use SBP-SET to
`make settings before running programs that take over the keyboard
`interrupt.
`
`After activating SBP—MIX from text—mode, you can make selections using
`either the keyboard or a mouse from the following menus:
`
`Card reset
`
`Master volume
`
`VOC volume
`LINE volume
`CD volume
`MIC volume
`FM volume
`
`FM channel
`
`ADC charmel
`
`ADC input test on/off
`Stereo on/off
`Exit
`
`Make a selection by moving the menu bar or by placing the cursor
`(pointer) on the selected function and pressing the left button on the
`mouse. From the keyboard, use the Up and Down Arrow keys and
`press Enter. The right mouse button or ESC cancels the selection.
`
`After making a selection from the main menu, an option menu is
`displayed. You highlight and select the option using the mouse or
`keyboard.

`
`SBP-MIX in Graphic Mode
`
`When activating SBP—MIX from the graphic mode, you will not get a full
`set of controls. Instead, functions are displayed only at the bottom line
`of the screen.
`
`You select a function using the Up and Down Arrow keys and set the
`mixer parameter for that function using Left and Right Arrow keys.
`
`One limitation in the graphic mode is that, you can control only the main
`volume of the mixer—there are no individual left and right volume
`controls.

`
`WINDOWS 3.0 APPLICATIONS
`
`JUKEBOX
`
`MIXER CONTROL
`
`For Windows 3.0 owners, we have included two Sound Blaster Pro
`
`application programs to let you see and bear how easily Sound Blaster
`and Sound Blaster Pro integrate with Windows. If you are interested in
`developing Windows 3.0 applications, by using Windows SBK (Sound
`Blaster Developer Kit), you can add the impact of Sound Blaster Pro
`audio to your programs. We have also included a program called SETUP
`to help you set the Sound Blaster Pro settings in the WIN.INI file.
`
`Naturally, running these programs requires Microsoft Windows 3.0 installed
`in your system. The programs included are:
`
`Jukebox
`I
`I Sound Blaster Pro Mixer Control
`
`I
`
`Setup
`
`Installation
`
`Installation is relatively easy, however you need to follow the instructions
`closely. If you have any problem running these applications, check your
`installation.
`
`Moving the DLL
`The DLL (Dynamic—Link Library) is necessary for Windows applications.
`We have included the Sound Blaster DLL (SNDBLSTDLL). You should
`
`move the DLL to the Windows directory so you can use it with other
`Sound Blaster Pro Windows applications.
`
`To move the DLL:
`
`1. Change to the \SBPRO\Wl1\lDOWS subdirectory.
`
`'
`
`2. Copy SNDBLST.DLL to the WINDOWS directory (Normally this is in
`C:\WINDOWS).
`
`144
`
`14 - 3
`
`144
`
`
`
`SIJIINII BLASTE|IQ,%
`
`3. Delete the SNDBLST.DLL file in the \SBPRO\WINDOWS
`
`subdirectory.
`
`Setting the Windows Environment
`
`To keep your Windows neat and to make Sound Blaster programs easier
`to find and execute, create a program group for your Sound Blaster Pro
`Windows 3.0 applications.
`
`To create the program group:
`
`1. Select the File menu of Windows Program Manager then select
`New.
`
`2. Select Program Group in the dialog box
`
`3. Type Sound Blaster Pro in the Description box and click on the OK
`button or press Enter. A blank window titled Sound Blaster Pro is
`displayed.
`
`4. Select File, New and Program Item.
`
`type
`and
`the Description box
`in
`5. Type _]ukeBox
`C:\SBPRO\W]NDOW'S\JUKEBOX in the Command Line box. You
`will see an icon representing]ukeBox appear in the Sound Blaster Pro
`Window.
`
`6. Repeat steps four and five, except this time type Mixer for the De-
`scription and enter C:\SBPRO\WINDOWS\SBMlXER in the
`Command Line. The Mixer icon is displayed.
`
`7. Repeat steps four and five, except type Setup for the Description and
`enter C:\SBPRO\WINDO\VS\SETUP in the Command Line. The
`
`Setup icon is displayed.
`
`Note: These steps assume you have installed the programs in the C hard
`disk the \SBPRO\\‘K/INDOWS subdirectory.

`
`
`SIJIINII BLASTEBW
`
`Setting the WlN.lNI Configuration
`
`The WINJNI file, normally found in the WINDOVVS directory, contains
`information required by Windows to run applications correctly. To let
`Windows know the Sound Blaster Pro I/O, Interrupt and DMA channel
`settings, they need to be placed in the \X/'IN.INI file. Since WININI is an
`ASCII file, you can use a word processor or text editor to add the Sound
`Blaster Pro settings. The file must be stored in ASCII.
`
`However, we have made it easier for you to change the '\X/'IN.INl file by
`including our Windows program, SETUP. Using this program, you can
`scan the current hardware configuration, enter
`settings, or have the
`program add the following defaults to the WININI file:
`
`[SoundBlaster]
`P01't=220
`
`Int=7
`
`DMA= 1
`
`Note: Port refers to the Sound Blaster Pro 1/0 address; Int is the DAC
`
`(Digital to Analog Converter) interiupt and DMA is the Direct Memory
`Access Channel.
`
`If you have changed the jumper settings on the Sound Blaster Pro card,
`you need to change the WININI file to match.
`
`Selecting Auto Scan in SETUP lets you scan the current hardware
`configuration. You can then manually enter the I/O port address,
`interrupt and DMA channel settings. After verifying the settings, SETUP
`makes the necessary changes in the WINJNI file.

`
`To run setup:
`
`1. Double click on the Setup icon in the Sound Blaster Pro window.
`
`2. When the dialog box appears, select the card you have installed:
`Sound Blaster or Sound Blaster Pro.
`
`5. When the 1/0 port dialog box appears, the default will be selected.
`If it has not been changed, select OK. If the setting is not correct a
`message box will appear telling you that the setting is incorrect and
`return you to the dialog box.
`
`4. Make or leave the default setting on the Interrupt and DMA settings.
`
`JukeBox plays MIDI files. (Files with extension .MID). This program
`provides a demonstration of the Sound Blaster Pro in the Windows 3.0
`environment. The program was written using the Microsoft Windows
`Development Kit and the Sound Blaster Developer Kit
`(SBK for
`Windows).
`
`]ukeBox uses the same conventions as most Windows applications. You
`can use the mouse, or the keyboard to make selections. You can double
`click with the left mouse button to select files or change directories.
`Without a mouse you can use the Tab key to move from option to
`option. When the desired function is highlighted, press the Enter key
`to execute this operation. You can also use the Alt key and the underlined
`character to select menu items.
`
`The MIDI files list displays any file with the .MID extension. We have
`included some sample files for you to play with. The Play Queue box
`is where you place the MIDI files to play. The MIDI files are played in
`the order they appear. You can skip or remove a file at any time.

`
`Quick Reference for Problem Solving
`
`Help for Installation
`
`Read this if you have problems installing Sound Blaster Pro. (Refer to:
`Common Problems Encountered)
`
`When installing the Sound Blaster Pro Card, beware of possible
`hardware conflicts with other adaptor cards.
`
`Each adaptor card may contend for Various CPU resources, there are
`three possible sources of hardware conflicts :
`
`D DMA channel conflict
`
`D
`
`D
`
`IRQ (Interrupt Request) lines conflict
`
`I/O address conflict
`
`In the case of Sound Blaster Pro, it uses :
`
`D DMA Channel 1 by default, for its digitized voice input/output
`
`DMA operations.
`
`D
`
`D
`
`Interrupt default at IRQ 7 (used for voice/MIDI operations)
`Jumper selectable at IRQ 2,
`IRQ 10, IRQ 5 and IRQ 7
`
`I/O address : 22OH - 237H as default. Jumper selectable at :
`22OH and 24OH. FM music chip also uses addresses 3881-1 and
`3891-i. Joystick port uses the standard address of 200—207H
`
`158
`
`158
`
`
`
`SIJIJNII BLHSTEBW;
`
`DMA Conflict
`
`The DMA channel used by the Sound Blaster Pro is selectable from 0,1
`and 5. It can share a DMA channel with other adaptor cards, provided
`that these cards can also share DMA channels.
`
`Other cards using DMA channels can have their DMA channels
`selectable. We suggest that you change the others cards‘ DMA
`Channel to either Channel 0 or Channel 5, if a conflict occurs.
`
`Interrupt Line (IRQ) Conflict
`
`The Sound Blaster Pro uses interrupt line IRQ7 as default. Some printer
`interface (LPT1:) snatch away the IRQ7 even though it never requires
`the interrupt.
`
`In the rare case of interrupt conflict with another 1/O card, you can
`change the interrupt of the Sound Blaster Pro to IRQ2 or IRQ5
`
`C See Table 1 for the best IRQ line to use.)
`
`We don’t suggest using IRQIO, because there are too many existing
`software packages that do not allow the selection of IRQ10.
`
`I/O Address Conflict
`
`The possibility of conflict on the default I/O address of 22OH is very
`small. We advise against changing this I/O port address. Changing
`from this default I/O address means that you have to re-install many
`software programs that support Sound Blaster Pro.

`
`Common Problems Encountered
`
`PROBLEM
`
`TEST-SBP’s Error 0400
`
`CAUSE
`
`Conflict on DMA Channel 1 with scanner card
`
`or network card, or other special cards that
`uses DMA channel 1.
`
`REMEDY
`
`Remove scanner card or network card (if you
`have one) and re-install its DMA to Channel 3.
`You need an AT machine to resolve this
`
`conflict. (see DMA CONFLICT)
`
`Other cards that could possibly use DMA
`Channel 1
`are: diskette COPY cards, SCSI
`
`cards or any special card. Remove these
`special cards one by one and run TEST-SBP to
`see if the error message disappears.
`If the
`error disappears, then the card that is just
`removed is in Conflict with Sound Blaster Pro.
`
`Check the card’s manual for re—installing its
`DMA.
`
`PROBLEM
`
`TEST-SBP's ERROR FOUND ON INTERRUPT
`
`CAUSE
`
`REMEDY
`
`Conflict on IRQ7, your system uses up IRQ7
`
`Remove Sound Blaster Pro from your system,
`and re-install its Interrupt jumper (refer “location
`of jumper” for more details) from IRQ7 to IRQ2
`or IRQ5.
`If you have used up IRQ2 and IRQ5 for some
`other card, you can try to look at IRQ7 again.

`«V
`
`If it is also used up, try to look for the jumper
`on your system board or Parallel 1/0 card that
`allows you to disable IRQ7 for LPT1:. You can
`consult the respective manual or your computer
`vendor on how to do this.
`
`PROBLEM
`
`Voice Recording too soft.
`
`CAUSE
`
`REMEDY
`
`PROBLEM
`
`CAUSE
`
`REMEDY
`
`Microphone used is not sensitive enough.
`
`Use a microphone that has a 600 ohm
`impedance and a sensitivity of -75 dB or better
`for good recording.
`(As a rule of thumb, one that costs more than
`
`US$30 should do the job. Remember to buy a
`1/4 inch to 1/8 inch adaptor-jack if
`the
`microphone has a 1/4 inch jack) A condenser
`microphone would work well.
`
`Background static noise from the speakers.
`
`Noisy power supply of the computer system.
`
`Computer systems are well—known to be the
`greatest producers of electrical noise. Much
`care had been taken in the design of Sound
`Blaster Pro’s bui1t—in amplifier to reduce as
`much noise from the computer’s power supply
`as possible. There are, however, some
`computer systems that simply produce too
`much noise. These noise are picked up and
`amplified to audible range when the power
`amplifier is set at a high volume. There is no
`good remedy here, except to turn down the
`volume control. If louder volume is desired,
`
`try to amplify using an external amplifier.

`
`PROBLEM
`
`:
`
`“No Interrupt vector available” error when
`
`running SBFMDRV.
`
`CAUSE
`
`: All the DOS software interrupt vectors (INT
`80H - OBFH) are taken up by a resident
`program that is misbehaving.
`
`REMEDY
`
`: Most commonly,
`
`the misbehaving resident
`
`program is a DOS MENU resident program in
`your AUTOEXEQBAT file. You can avoid
`problem with this kind of resident programs in
`the following ways:
`
`I Boot the system again from a DOS diskette
`and then run SBFMDRV from the \pSBPRO
`sub-directory to confirm that the problem
`is solved.
`
`I During the booting process of the fixed
`disk, press Ctrl—Break to abort
`the
`AUTOEXEC file. Then run
`
`\SBPRO \SBFMDRV
`
`I Execute \SBPRO\SBFMDRV before
`
`running the misbehaving program in your
`AUTOEXEC file.
`i.e.
`insert
`the line
`
`\SBPRO\SBFMDRV
`
`before
`
`the
`
`misbehaving program. This might only
`solve some cases with a partially
`misbehaved program. With a badly
`misbehaved residentprogram, you might
`have to remove it from the AUTOEXEC
`
`totally.

`Note:
`
`Removing JP4 will not remove the

`Pro’s joystick port.
`
`joystick not working properly in some
`programs.
`
`This is a classic problem with PC’s joystick port
`which uses the CPU timing to calculate joystick
`position. When a CPU is too fast and the
`program does not take good care of the
`change in CPU speed, the wrong calculation
`would cause the joystick port to move to its
`unusable range.
`
`The Sound Blaster Pro adheres to this PC
`
`standard and hence would inherit the same
`
`problems. You could confirm that the joystick
`port is working if some programs can handle
`the joystick properly.
`
`The possible remedy here is to switch the
`computer to its lowest possible speed.

`
`The Sound Blaster Pro complies with the
`International MIDI Association recommended
`
`standard. The MPU401 has some intelligence
`in its MIDI implementation. This intelligence
`could be easily emulated by a small driver
`routine in the PC. Hence, programs that run
`on the MPU401 cannot work directly on the
`Sound Blaster Pro. They must be modified by
`their respective software companies in order
`to run on the Sound Blaster.
`
`Before buying any MIDI software, please
`ensure that they support Sound Blaster Pro.
`
`Computer hangs after running one of the
`Sound Blaster Pro program.
`
`Conflict with other adaptor cards in the system.
`
`To identify the possible conflicting card, remove
`all the non-essential cards one by one from the
`system;
`leaving only the essential cards :
`Diskette/Fixed Disk Controller Card and Video
`
`Adaptor Card in the system.
`
`After each card is removed, run the same
`program that hangs the system.
`If problem is
`solved,
`then the last card removed has a
`possible conflict with Sound Blaster Pro. Try
`to determine whether it
`is a DMA conflict,
`Interrupt conflict or 1/0 address conflict by
`looking up the manuals of this card.
