Spacewalker Sound System HOT-255 Sound Card
The Spacewalker Sound System HOT-255 Sound Card is designed based
on ENSONIQ’s breakthrough AudioPCITM technology to take full advan-
tage of the PCI bus’ architecture, while maintaining compatibility with
older legacy software. Legacy game compatibility was originally a prob-
lem when considering a PCI based sound card solution. The problem was
that existing software and games for the PC had been designed to run on
ISA based sound cards. To function properly, those cards must write di-
rectly to the inherently slow ISA Direct Memory Access (DMA) control-
ler. These signals are not present on the PCI bus. AudioPCI™ allows legacy
software to function as if the ISA signals are present, while utilizing the
faster speed of the PCI bus.
AudioPCI™ technology was developed by ENSONIQ, a recognized leader
in the electronic musical instrument industry. The same advanced chip
designs that function as the engines for ENSONIQ’s line of professional-
level synthesizers, samplers, and effect processors have been used in
AudioPCI™.
What is AudioPCI™ ?
AudioPCI™ technology is a combination of hardware and software that
provides the highest quality in PC sound and the greatest compatibility
with current standards.
Why PCI?
The PCI bus is far superior to the ISA bus. It is capable of transferring data
on a wider 32-bit bandwidth bus. This allows much more data to pass from
the PCI bus to the host processor. The ISA bus is only capable of 16-bit
bandwidth transfers. Using the PCI bus will allow a 4 to 20 times increase
in speed over much slower DMA transfers on the ISA bus. This drastically
reduces the overhead on the host CPU. This tremendous processing power
opens up new possibilities for sound cards. Real-time software based sound
fields are now possible without bogging down the host CPU.
Here’s a brief overview of Spacewalker Sound System HOT-255 Sound
Card’s main features:
Synthesizer
•Provides up to 32 voices of wavetable synthesis.

INTRODUCTION
•Includes two and four megabyte General MIDI/ Roland MT-32
sound sets as well as AdLib/SoundBlaster Pro and FM synthe-
sizer emulation.
•Because of the high data transfer rates that the PCI bus will al-
low, HOT-255 is able to utilize a flexible method of storing and
accessing wavetable sounds. All 128 General MIDI instrument
sounds are stored on the PC’s hard drive and accessed using the
computer’s on-board RAM. This technology allows for expand-
able sound sets.
Digital Audio
•Allows the recording of CD-quality stereo sound (up to 16 bits,
48.0 kHz sampling rate) from Aux, CD and TV Tuner Inputs as
well as from the internal synthesizer.
•Allows the recording of sound from the Mic Input with or with-
out 5-volt BIAS power or 30-dB boost.
•Allows the recording of sound from the Modem/TAD Input/Out-
put.
•Playback of stereo wave samples of 8- or 16-bit sound.
•Enables playback of standard PC Wave files (.VOC,.WAV, etc.).
MIDI •Provides an MPU-401 compatible MIDI interface, including
MIDI In and MIDI Out/Thru (requires external cable, not sup-
plied).
•Allows the recording of MIDI events from an external MIDI key-
board controller.
•Enables playback of standard PC MIDI files (i.e., .MID, .ROL,
etc.) to either the on-board synthesizer or to an external synthe-
sizer.
Mixer
Provided software mixer allows synthesizer and digital audio output to be
mixed with signal arriving at the card’s CD, Aux, Mic, Modem and TV
Tuner Inputs.

•The HOT-255 sound card in anti-static bag
•The HOT-255 User Manual
•The HOT-255 Installation CD with Manual
Preparing Your Computer
As you install the HOT-255, follow these basic precautions:
Some PC’s maintain power to the motherboard even when the power
switch is turned off.
•If it is necessary to disconnect peripheral equipment cables from
the back of the computer, be sure to note cable positions for proper
reconnection later.
INSTALLING HOT-255

11
INSTALLING HOT-255
•Remove the computer cover’s mounting screws and save them
for its replacement. Slide the cover off the computer and place it
aside while you install the HOT-255.
•Handle the card by the edges only, being careful not to touch
edge connectors or exposed circuitry.
•Keep the board inside its protective anti-static packaging until
you are ready to install it.
•Never place the board on a metal surface.
•Static electricity can damage your equipment, but can be easily
avoided. Before installing any internal optional equipment such
as the HOT-255, consult your computer manufacturer’s manual
regarding grounding, power connection, and peripheral card in-
stallation.
You can ground yourself by wearing an anti-static wrist strap (avail-
able at most electronics stores). To use this wrist strap:
1. Place the wrist strap on your wrist. Look for an alligator clip on
the other end of the wrist strap’s elastic cord. Some wrist straps
require you to snap (attach) the clip to the elastic cord.
2. Attach the alligator clip securely to the edge of a D-shell shaped
connector in one of the computer’s serial ports (the D-shell shape
surrounds the pins) or to an unpainted portion of the computer’s
chassis. To maintain proper grounding, the clip must remain se-
curely attached (grounded) to the serial port connector or to an
unpainted portion of the computer’s chassis throughout the in-
stallation procedure.
If you don’t have an anti-static wrist strap, you can ground yourself
by touching and maintaining continuous contact with an exposed
metal surface of the computer (i.e., an unpainted portion of the
computer’s rear panel) while handling or touching any chips or in-
ternal components such as the HOT-255.

INSTALLING AUDIOPCITM SOFTWARE
Configuring the ENSONIQ AudioPCI™
AudioPCI™ requires one 64-byte I/O Range and one PCI Interrupt to func-
tion in Windows 95; however, additional resources must be allocated to
enable legacy compatibility in an MS-DOS Prompt and MS-DOS Mode
applications. See the section entitled “Configuring the ENSONIQ
AudioPCI™ Legacy Device” on page 21 for more information on config-
uring the AudioPCI™ Legacy Device.
The AudioPCI™ Properties window contains several tabs with the con-
figuration options for the HOT-255. To open the AudioPCI™ Properties
window follow the steps below:
1. Open the Device Manager by selecting Start Settings
Control Panel and double-clicking System.
2. Double-click “Sound, video and game controllers” from the hard-
ware tree under the Device Manager tab.
3. Double-click ENSONIQ AudioPCI™.
Figure 3: ENSONIQ AudioPCI™ Settings Tab
MIDI Synthesizer Wavesets
The first section under the Settings tab contains a drop down menu that
will allow you to choose from either the 2-megabyte wavetable instrument
set or the 4-megabyte instrument set included with AudioPCI™. It is likely
that new wavesets will be available in the future, so an Add Waveset button
is included. Generally, the larger the waveset the better it will sound.

19
INSTALLING AUDIOPCITM SOFTWARE
To select from existing wavesets:
1. Click the down arrow in the “MIDI Synthesizer Waveset” section to
display the drop down box with all the available wavesets.
2. Highlight and click the waveset you wish to use.
3. Click OK to close the ENSONIQ AudioPCI™ Properties window.
To load a new waveset:
1. Click the Add Waveset button in the “MIDI Synthesizer Waveset”
section.
2. Browse… to the new waveset file (*.ECW) and click OK.
Note: The *.ECW file will be copied to the folder indicated by the
SNDSCAPE environment variable in the AUTOEXEC.BAT.
(i.e., C:\EAPCI)
3. The new waveset will appear in the MIDI Synthesizer Waveset drop
down menu. Select it if it is not selected.
4. Click OK to close the ENSONIQ AudioPCI™ Properties window.
Locking the MIDI Waveset
The “Lock MIDI Waveset” checkbox in the Settings tab determines how
the AudioPCI™ manages the waveset memory.
If checked the entire waveset is locked into physical memory each time the
driver is initialized on boot up or the MIDI Device is in use. When the
MIDI Device is closed the waveset is unlocked, so the memory is available
to other applications when the MIDI device is not in use.
If unchecked only the wavetable sounds in use are locked into memory. If
a sound is not being played it will not be locked into memory. This means
that as a complicated MIDI sequence is played there may be a delay as
each instrument is locked to and paged out of memory. The only time this
should be necessary is when another memory-heavy application has a
greater need for RAM than the MIDI device.
For MS-DOS Prompt and MS-DOS Mode applications the entire waveset
is always locked in memory regardless of this setting.

20
INSTALLING AUDIOPCITM SOFTWARE
LegacyEmulation
AudioPCI™ legacy emulation provides applications with the resources
necessary to function in MS-DOS Mode or an MS-DOS Prompt.
AudioPCI™ does not require most of the resources used by non-PCI (also
called ISA or Legacy) devices. To ensure compatibility with applications
designed to function with those non-PCI cards, the AudioPCI™ Legacy
Device is used.
When legacy emulation is enabled in the Settings tab the AudioPCI™
Legacy Device will appear in the Device Manager. See the section en-
titled “Configuring the ENSONIQ AudioPCI™ Legacy Device” on page
21 for more information.
Allow LPT Interrupt Sharing
To conserve system resources LPT interrupt sharing should be enabled.
When this box is checked the AudioPCI™ Legacy Device attempts to use
the same interrupt that the LPT port is using, which is typically 5 or 7.
Joystick Port
To enable the AudioPCITM joystick port in Windows 95 the Gameport Joy-
stick drivers must be installed. The Gameport Joystick driver is provided
with Windows 95. The Gameport Joystick device will appear in the De-
vice Manager after an initial install of the AudioPCI™ or when the “Joy-
stick Port Enabled” box is checked in the AudioPCI™ Settings tab.
Note: If another game card is installed in the system, the “Joystick Port
Enabled” box should not be checked.
Microphone BIAS
If the “Microphone BIAS” box is checked 5-volt BIAS power will be ap-
plied to the Mic Input. This is necessary for electret condenser micro-
phones to function. Uncheck this box when using a dynamic microphone.
MS-DOS Mode and MS-DOS Prompt do not have microphone support.
Add Mixer to Taskbar
When this box is checked the ENSONIQ Mixer will be added to the sys-
tem tray of the taskbar. This checkbox doesn’t affect the Microsoft volume
control, which is controlled by the Multimedia applet of the Control Panel.
