The ADA995 is a THX Certified, high power multimedia speaker system designed specifically for superior audio performance and seamless integration to your computer system. The ADA995 Multimedia Speaker System consists of six interconnected speaker components:
A rotary bass level control is located on the rear of the subwoofer. Volume, mute, and all other speaker system controls are accessed through the computer system or multimedia keyboard.
The satellite speakers and center speaker are magnetically shielded to provide protection against monitor image distortion.
The subwoofer is NOT shielded and should be placed at least 2 ft (0.6 m) away from computer monitors, other video display devices, computer hard drives, and any other magnetically encoded media.
Certified products must meet an exclusive set of performance standards
established by THX Lucasfilm® which is a division of the world-renowned
film production company, Lucasfilm Ltd. These THX performance standards
were originally developed in response to George Lucas' personal desire to

Santa Cruz Sound Card
This is the Santa Cruz sound card. The jacks can be found at the back of
your PC. You will use the yellow, lime green, and black output jacks on the
card to connect the ADA995 Multimedia Speaker System to your computer.
YELLOW: Center & Sub (LFE) channel outputs (Note: LFE stands for Low Frequency Effects)
PINK: Microphone input
BLUE: Line input
GREEN: Front Left & Right channel outputs
BLACK: Rear Left & Right channel outputs
The Power On/Off rocker switch is located at the rear of the subwoofer.
The Subwoofer Level rotary control is located at the rear of the subwoofer.
|Note: The Subwoofer Level control affects the subwoofer level only. All other adjustments for the speaker system are made using the computer or keyboard controls, including overall system volume.|
In order to help diagnose system problems, an output jack for speaker testing is located at the rear of the subwoofer.
This indicator warns when digital signals are detected by your ADA995 Multimedia Speaker System.
The placement of the Subwoofer in your room affects its output. The
difference in output between corner placement and side-wall placement is about
6dB - in favor of corner placement. You can adjust the subwoofer sound level
using the Subwoofer Level control. This allows a variety of roomplacements.
The subwoofer's shape has been specifically designed so it can easily fit along the right or left side of your desk. If your desk is centered in the middle of a wall, it is recommended that you place the subwoofer alongside that same wall. You can also lay it flat; you can even place it under desk drawers if space permits.
We recommend that the subwoofer be placed within 5 ft (1.5 m) of the
satellite speakers. The distance between the subwoofer and satellites affects
the sound in the region where the subwoofer's output overlaps the satellites'
output. If the distance is greater than 5 ft (1.5 m), there is a possibility
that the subwoofer and satellites' output will cancel in the overlap region.
This would result in a less punchy bass.
|WARNING: The subwoofer is not magnetically shielded. The subwoofer should NOT be placed near video display devices such as a TV or computer monitor. The subwoofer should NOT be placed near computer hard drives. Position the subwoofer at least 2 feet (0.6 m) away from computer hard drives. Do not place diskettes, zip disks or other magnetic media on top of the subwoofer.|
The subwoofer has two large openings at its rear called acoustic ports. These are critical acoustic components and must not be blocked by a wall or other hard surface. The port needs a minimum of 4 in (10 cm) clearance from a wall or other obstruction.
Because placement of your satellite speakers is important for sound quality, the acoustic response of the satellites was carefully optimized with typical desk, monitor and keyboard configurations. It is recommended that the satellites be placed on the left and right side of the monitor. The satellite speakers are magnetically shielded and can be placed close to the computer monitor without distorting video images. Best stereo effects are obtained by placing the speakers as far apart as is practical.
The satellites can be placed even with the front surface of the monitor's screen or 4-5 in (10-15 cm) behind it. For better stereo imaging, try placing the satellite speakers 5 in (12.5 cm) back from your monitor's screen and between 6 and 18 in (15-46 cm) from the sides of the monitor.
The center speaker should be located between the front left and right satellites, near the middle - for instance, on top of your computer monitor. It has two stands allowing two different mounting positions.
The center speaker comes assembled for horizontal placement. It is designed to stand firmly on a traditional computer monitor. Its stand is detachable and can be replaced with the extra stand enclosed with your system for vertical orientation.
Vertical stand for center speaker: If you wish to use the center speaker in a vertical position, you must install the extra stand included with your ADA995 system. Detach the horizontal stand by unscrewing its single base screw. The vertical-position stand is keyed to insert in the matching screw hole located on the back of the center speaker. Insert the vertical stand, and use the same screw to attach it to the center speaker. A small rubber strip (included with your system) can be attached to the bottom edge of the speaker housing as shown below. This strip allows the speaker to remain stationary on smooth surfaces. You can now position the center speaker on a desktop or other flat surface, but NOT the top of your computer monitor.
Flat panel monitors are too narrow to mount the center speaker properly.
Tabletop placement is recommended The center speaker should be located
either in its horizontal orientation directly in front of the flat display
(shown) or in its vertical orientation on either side of the display. See the
|Note: Do not use the center speaker without a stand attached. It is not designed for use without a stand. The center speaker is unstable without either stand installed and could sustain damage from a fall.|
The best surround effects are obtained by placing the rear surround speakers slightly behind the user and approximately the same distance apart as the front satellite speakers. The rear speakers should be positioned so that they point toward the computer user's likely location when operating the system. In addition, excellent results are obtained when the surround speakers are in line with, and slightly above the listener's ears.
For your convenience, two wall-mount brackets are enclosed for use on the rear speakers. If your listening environment permits convenient wall-mount access, you may wish to take advantage of this feature by following these instructions:
Using the concepts discussed in subwoofer placement, Acoustic Port information, front speaker placement, center speaker placement, and rear speaker placement above, a typical surround 5.1 / 6 piece system placement is shown in the diagram above. Notice that the subwoofer is placed more than 2 ft (0.6 m) away from the PC and its enclosed hard drive, more than 4 in (10 cm) from the wall and the acoustic ports do not appear to be obstructed.
Each Satellite speaker has a cable with a colored, mechanically-keyed plug attached to the cable end. To help you make the right connections from each speaker to the subwoofer, the following features have been used:
Color Coding: Each satellite speaker cable has a color coded plug at its end. The input jacks on the back of the subwoofer are coded with matching colors. As an example, the left front satellite speaker has a brown connecting plug. This plug is inserted into the left front jack with the brown color marking located at the back of the subwoofer. All other connections are made in the same way.
Name on Satellite Plug
Plug and Jack Color Code
|LT FRNT||Brown||Left Front speaker|
|RT FRNT||Orange||Right Front speaker|
|LT REAR||Gold||Left Rear speaker|
|RT REAR||Purple||Right Rear speaker|
Mechanical Keying: In addition, each satellite speaker cable plug is mechanically keyed. The plug can fit in its own jack on the back of the subwoofer.
You may wish to refer to the Quick Start Guide included with your system for an overview of the connections detailed below.
|Note: The names LEFT and RIGHT satellites always refer to the location of the satellites as you see them seated at the computer. However, these connections drawings show a back view of all the speakers and the subwoofer. Therefore, in these drawings the RIGHT FRONT and RIGHT REAR speakers appear to the left, and the LEFT FRONT and LEFT REAR speakers appear to the right.|
Now you are ready to connect the subwoofer to the sound card. Use the triple input cable found at the back of the subwoofer. The triple input cable is permanently wired to the subwoofer. The three cables separate from one another several inches from the end, and each of the three cables ends with a different colored plug:
Connect the black plug to the black jack on the sound card.
Connect the lime green plug to the lime green jack on the sound card.
Connect the yellow plug to the yellow jack on the sound
|Note: Do NOT connect the subwoofer to a power source until all speaker system connections have been made.|
|Caution: To prevent electric shock do not use this (polarized) plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure.|
To increase the subwoofer level, turn the rotary control clockwise. To decrease the subwoofer level, turn the rotary control counter-clockwise
The Subwoofer Level control is an important feature of your
ADA995 Multimedia Speaker System. It allows you independent control of subwoofer
volume level for fine-tuning the system.
|Note: The Subwoofer level control affects the subwoofer level only. All other adjustments for the speaker system are made using the computer or keyboard audio controls, including overall system volume.|
The optimum subwoofer level setting varies for different types of music. You
may find the chart below useful. It shows typical settings for popular music
types and DVD audio. The THX position is the system default position.
|Subwoofer Placement||Music Type||
|Corner of room||Classical||Minimum to ~1/4|
|Corner of room||Rock||~1/3 to ~1/2|
|Corner of room||Rap||~1/3 to ~2/3|
|Corner of room||Jazz||Minimum to ~1/4|
|Corner of room||DVD||~1/3 to ~2/3|
|Middle of the wall||Classical||~1/4 to ~1/3|
|Middle of the wall||Rock||~1/2 to ~2/3|
|Middle of the wall||Rap||~1/2 to full clockwise|
|Middle of the wall||Jazz||~1/4 to ~1/2|
|Middle of the wall||DVD||~1/2 to full clockwise|
|Note: When rotating the
Subwoofer Level control, the center position can be detected by touch. A
slight notch or catch in the smooth rotation of the knob can be felt when
the mid level is reached.|
Speaker controls software panel
|NOTE: This speaker system is designed to produce the best possible sound in your listening environment right out-of-the-box. No additional equalization is necessary.|
TIP: It is not necessary to switch off your speaker system each time you turn off your PC. The speaker system can remain powered.
To maximize your enjoyment from the speaker system when listening to an audio CD, the Virtual 5.1 mode should be engaged in the speaker controls software. This will enable all six speakers to operate.
|IMPORTANT NOTE ABOUT 5.1 CHANNEL AUDIO: Not all DVD movies have or default to a 5.1 channel soundtrack. This is particularly true for older movies that weren't originally made with multi-channel sound. Be sure to check the DVD's Language menu and if a 5.1 channel soundtrack is available, select that option. Otherwise, the center speaker may not emit sound.|
Your system comes pre-configured for 5.1 channel audio playback so no setup changes are necessary. However in the event you changed the configuration, the speaker controls software should be set up this way:
Your DVD software also comes pre-configured for 5.1 channel audio playback but it assumes you are seated normally at your desk, a typical distance away from your video monitor. If you have a 21 in. or larger video monitor or just prefer to sit farther back (>4 feet), you should uncheck the Listening within 4 feet of the monitor check box in your DVD software to optimize the center channel sound for this distance. Here is how to do it:
When seated normally at your desk, please repeat the steps above but put a check in the Listening within 4 feet of the monitor check box.
To maximize your enjoyment from games and take advantage of the 3-D positional audio effects many games provide, your speaker mode should be set to 4 Speaker.
|NOTE: In the 4 Speaker Mode, the center speaker will not emit sound.|
If a digital signal is detected, the S/PDIF indicator will illuminate. This indicator is located on the rear of the subwoofer, to the left of the color-coded satellite jacks.
If a digital signal is detected, which can only happen when the VersaJack is set to Digital Out in the speaker controls software, the center speaker will be muted. The LFE (Low Frequency Effects) input channel in the ADA995 will also be muted. Since this channel is part of the total mix of sound signals directed to the subwoofer, you probably won't be able to detect the muting of the LFE channel.
Speakers control software: Remember, almost all speaker controls are found in your speaker control software. Use the computer keyboard for system volume adjustments. When problems are encountered, carefully check all software settings first. Refer to the software documentation to make sure that settings are correct for the desired output, then restore defaults. Once software settings are verified and determined to be correct, proceed with the Table of problems, possible causes, and solutions below.

Power off the ADA995 Multimedia Speaker System using the rocker switch on the back of the subwoofer. Unplug the subwoofer from the AC outlet.
The fuse is located on the back of the subwoofer (to the right of the On/Off rocker switch and green LED light). Unscrew the black cap and visually check to see if the filament is in place. If it is not in place, then the fuse is blown.
A spare fuse is included with your system. It's ratings are 5.0 amp,
250 vac. Should you need to purchase another, the replacement fuse is a Radio
Shack part # 270-1067. You may replace the fuse only with a fuse of the
same type and value as this fuse.
The ADA995 has a built-in diagnostic function to test the operation of all speakers. This test is usually performed when no sound is detected from the speakers, and after all other solutions have been tried in the "Table of problems, possible causes and solutions."
Locate the DIAG OUT jack on the back of the subwoofer. This connection is used with the plugs on the subwoofer's triple cable. To use this function:
|Note: Do not touch the
exposed ends of the triple cable plugs with your fingers during this
procedure. Because the subwoofer is powered on, touching the plug
