Gaming System Operation (See Figure 2)
To connect a Gaming System to the ADA890:
1. Connect the Red and White RCA plugs from the Game System to the respective Red and White jacks of the adaptor cable.
2. Connect the Lime jack of the adaptor cable to one end of the Lime input cable. Connect the other end of the Lime input cable to the FRONT INPUT on the subwoofer.
Near Field Stereo/Surround Sound Operation
(See Figures 3 and 4)
If it is desired to convert to a 3-speaker system, follow the instructions and the pictorial view below.
1) Separate the left and right surround speakers from their stands by gently pulling the speaker up (See Figure 3).
2) Remove the left (WHITE) and right (PURPLE) speaker wires from the subwoofer.
(Set speaker stands aside for future use)
3) Remove the supplied rubber plugs from the top of the satellite speakers.
4) Mount the surround speakers on top of the satellite speakers as shown in Figure 3.
Be sure to line up tabs on the satellite and surround speakers. Gently push down on the satellite speaker to fit into place. (The connections to the satellite speakers
are made automatically once the surround speakers are mounted)
Your ADA890 system is now ready for use.
Placement of Speakers (See Figures 5 and 6)
All stereo information is heard from the satellite and surround speakers. The subwoofer contains no stereo information and its sound is non-directional. As a result, the
subwoofer does not necessarily have to be placed in any particular relationship to the satellites. Placing the subwoofer on the floor close to a wall or corner of a room
provides maximum bass efficiency. The subwoofer is not magnetically shielded and should not be placed near video displays. *
Near Field (3 Piece)
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.
Enhanced Surround Sound (5 Piece)
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.
Excellent results are obtained when the surround speakers are in line with, and slightly above the listener's ears.
*Note: Care should be taken not to place diskettes or other magnetic media on the subwoofer.
Using the Speaker System (See Figure 7)
POWER. Press this button to turn power on. The LCD display will illuminate and show the last mode of operation. Press again to turn power off.
MODE SWITCH. Pressing this switch repeatedly will access several modes of operation. Each time the MODE switch is pressed the LCD display will show which
mode is selected. The various modes of operation are described below.
STEREO. In this mode information obtained from the FRONT and S/PDIF** inputs is used. The front information is decoded to stereo. The S/PDIF information may
be PCM*** or Dolby Digital. The automatic decode circuit will process either one. If PCM is sensed it will decode to stereo. If Dolby Digital is detected all channels
will be mixed to provide stereo information. In this stereo mode sound will only be heard from the left and right front speakers and subwoofer. The center channel and
surround speaker will not be operational in this mode.
STEREO X 2. In this mode the operation is the same as for the STEREO mode. The exception is that the two surround speakers will be activated. The front left and
surround left speakers will be one stereo channel and the front right and surround right will be the other channel. The level of the surround speakers can be adjusted
separately. See SURROUND mode operation to make this adjustment. Advantages of operating in this mode are that the stereo effect can be enhanced and overall audio
is increased by the use of two additional amplified speakers. The center channel is not operational in this mode.
PRO LOGIC. In this mode only information obtained from the front analog input are used. All five speakers will be activated. The front left/right speakers will provide
stereo and center information and the surround speakers will provide surround information. No digital inputs (S/PDIF) will be processed in this mode.
**S/PDIF - Sony/Philips Digital Interconnect Format
***PCM - Pulse Code Modulation
QUAD. In this mode separate inputs are used for the FRONT and SURROUND channel sets (Refer to Figure 2). The front channel set input is the LIME input. The
surround channel set input is the BLACK input. The front information is decoded to stereo and feeds the front left/right speakers and the subwoofer. The surround
information provides the surround channel and also is sent to the subwoofer. All five speakers are operational in the QUAD mode.
DOLBY DIGITAL. In this mode only information obtained from the FRONT and S/PDIF inputs is used. The front information is decoded to stereo and subwoofer. The
S/PDIF information may be Dolby Digital or PCM. The automatic decode circuit will process either one. If PCM is sensed, it will be decoded to Prologic. If Dolby
Digital is sensed it, will be decoded to Dolby Digital and the front information will be reduced to a lower level. All five speakers are operational in this mode. This mode
reproduces analog and digital simultaneously.
Note: If your computer has a separate sound card with an S/PDIF output, you may use this output to feed the S/PDIF input with the front channel information. Refer to
your system documentation for its output information
BASS. The BASS button has two modes of operation: BASS level control or CENTER level control.
A) BASS LEVEL CONTROL. The bass level control is accessible in all modes of operation. If it is desired to increase/decrease BASS response, press this button.
The LCD display will show BASS. Also, the volume level indicators will show the last setting of the control. Rotate the master volume control clockwise to increase
bass and counterclockwise to decrease bass. As bass response is increased/decreased the volume level indicator bars will show in ascending or descending order the bass
level change.

B) CENTER LEVEL CONTROL. This function is only operational in Pro Logic and Dolby Digital mode. Depress and hold the BASS button until the function
indicator shows CENTER. Rotate the master volume control clockwise to increase center level and counterclockwise to decrease center level. The volume level indicator
bars will show in ascending or descending order the center level change.
TREBLE. The TREBLE button allows 2 modes of operation, TREBLE level control or SURROUND level control.
C) TREBLE LEVEL CONTROL. The treble level control is accessible in all modes of operation. If it is desired to increase/decrease TREBLE response, press this
button. The LCD display will show TREBLE. Also, the volume level indicator will show the last setting of the control. Rotate the master volume control clockwise to
increase treble and counterclockwise to decrease treble. As treble level is increased/decreased the volume indicator bars will show in ascending or descending order the
treble level change.
D) SURROUND LEVEL CONTROL. This function is operational in Pro Logic, Dolby Digital, Quad, and Stereo X2 modes. Depress and hold the TREBLE button
until the LCD display shows SURROUND. Rotate the master volume control clockwise to increase surround level and counterclockwise to decrease surround level. The
volume indicator bars will show in ascending or descending order the center level change.
NOISE TEST. To check the overall sound system a noise test is provided. To enter the NOISE mode, the system must be in the DOLBY DIGITAL or PRO LOGIC
MODE. Hold the MODE button down until the LCD display shows NOISE. (While the mode button is held down in the DOLBY DIGITAL mode, the LCD will
temporarily show STEREO, however, the mode is still DOLBY DIGITAL. In the PRO LOGIC mode while holding down the MODE button the LCD display will
temporarily show QUAD, however, the mode is still PRO LOGIC.)
The noise will sequence through each channel in approximately 2 second steps. The noise will be heard through each speaker if the system is operating properly. The
noise will continue to sequence through each channel until interrupted by pressing the MODE button. The purpose of the test is to make sure each speaker is working.
The noise generated is composed of a wide spectrum of audio frequencies which make it suitable to test all the speakers in the system.
MASTER VOLUME CONTROL. The MASTER VOLUME CONTROL provides many functions. It operates as a master volume control for the overall system and
can also be used to individually adjust the volume levels of BASS, CENTER, TREBLE, and SURROUND. If any one of the functions is selected and not adjusted within
a few seconds, the control reverts back to becoming a master volume control.
FLAT RESPONSE SETTING. To set the BASS and TREBLE controls to a flat response (default) and the CENTER and SURROUND controls to mid volume level
positions, both the BASS and TREBLE buttons must be depressed at the same time. The buttons must be kept depressed until the LCD display shows DOLBY DIGITAL.
The amplifier response is now flat (linear). Volume level indicator bars will show in the middle of the display indicating the flat response of the amplifier. If it is desired
to increase/decrease BASS or TREBLE response, press either of these button respectively. Rotate the master volume control clockwise to increase levels and
counterclockwise to decrease levels from the flat setting.
To access CENTER volume level settings the unit may be in Dolby Digital or Pro Logic mode. To access SURROUND volume level settings the unit may be in
the Quad, StereoX2, Dolby Digital, or Pro Logic mode. Press the TREBLE button until the LCD display shows SURROUND or hold the BASS control until the LCD
display shows CENTER. Adjust the master volume control clockwise to increase volume level and counterclockwise to decreased volume level of the SURROUND or
CENTER channels.
HEADPHONE USE. (See Figure 8) Headphone output is active in all modes. If it is desired to listen privately, a headphone jack is available in the side of the left
satellite. A headphone (not supplied) with a 3.5 mm(1/8") stereo plug. When the headphone is plugged into the headphone jack, the speakers are muted. The headphone
output is separately amplified and will have all the channels mixed. The master volume control is used to adjust the headphone volume. Remove the headphone plug to
restore speaker amplification.
AC LEVEL POWER INDICATOR. (Please Note: LED is located on front of Subwoofer) Under normal operating line voltages, the LED will glow lime. The LED
will glow red when the line voltage exceeds normal operation. In the red condition, protective circuits may turn off the audio amplifiers. The amplifiers will operate
again when the power indicator glows lime. If the indicator glows red continuously, inform your power company. They may need to reduce the line voltage to normal
levels.
DIAGNOSTIC SWITCH. (See Figure 2 for switch location) In the event it is necessary to troubleshoot the ADA890 to make sure all speakers are operating properly,
press this switch. All speakers will revert to a flat (default) response regardless of previous settings. A test tone**** will sequence to each speaker separately. Notice if
the speakers are working or sound is distorted or speaker levels are incorrect. This information will help a service technician. At the end of the test the mode will revert
to Dolby Digital regardless of the mode setting prior to performing the test.
The test can be operated as many times as required to assure the system is operating properly.
****To test the subwoofer, the frequency of the tone will change to one suitable for testing the subwoofer.
Remote Control Operation (See Figure 9)
The remote control can perform most of the manual operations. For best performance aim the front part of the control towards the infrared detector shown in Figure 6.
The functions of the control are listed below.
POWER. Press this button to turn power on. The LCD display will illuminate and show one of the modes previously selected. Press again to turn power off.
TREBLE. Press this button if it is desired to adjust the TREBLE level. The LCD display will show TREBLE. To increase/decrease treble volume press the plus (+) or
minus (-) part of the VOL button. The level indicators shown on the LCD display will increase in ascending order as treble volume is increased and will turn off in
descending order as treble volume is decreased.
BASS. Press this button if it is desired to adjust the BASS level. The LCD display will show BASS. To increase/decrease bass volume press the plus (+) or minus (-)
part of the VOL button. The level indicators shown on the LCD display will increase in ascending order as bass volume is increased and will turn off in descending order
as bass volume is decreased.
