Introduction

The ADA880 is a technologically advanced multimedia amplified speaker system featuring Dolby Digital AC3 and Dolby Pro-Logicsurroundsound and stereo reproduction. The amplifier inputs can simultaneously operate on analog and digital (S/PDIF)* audio signals.

The unit is comprised of a subwoofer and two satellite speakers. This combination provides surround sound on a desktop by utilizing side firing speakers. For enhanced surround sound the top speaker portion of each satellite can be separated and placed on a provided stand with long speaker wires. This enables the separated speakers to be placed for best surround sound performance. Equalizer circuitry automatically resets to conform to the changes that take place when the speakers are separated.

The satellite speakers are magnetically shielded and can be placed close to a monitor without disturbing images. The speaker in the subwoofer is not magnetically shielded and should not be placed close to a monitor.

Subwoofer frequencies are non directional, therefore, the subwoofer does not have to be located in any particular relationship to the satellite speakers. Placing it on the floor close to a wall, corner of a room or under a desk gives excellent results.

The main satellite speaker has status indicators to show the various conditions of operation. A master volume control is used to separately adjust bass, center, surround and treble settings. Once the individual functions are set, the control reverts back to becoming a master volume control. A remote control unit is supplied that can access all the manual functions. The remote control has a mute function that is not available when using the controls manually.

The AC3/PRO-LOGIC/STEREOdecode circuits operate automatically. If the unit is in the STEREO orPRO-LOGICmode and an AC3 signal appears at the input of the amplifier, the circuitry automatically switches over to AC3. This and other automatic features are explained under “Using the Speaker System.”

If analog and digital signals appear at the input of the amplifier, the analog signal is automatically reduced in volume level.

Setup

Do not plug the AC power plug into the wall outlet until all connections are made.

The ADA880 can be setup in two configurations. For ENHANCED SURROUND sound a 5-piecesetup is used. For near field STEREO/SURROUND sound a3-piecesetup is used. The two modes of operation are described below. The speakers are packaged and shipped in the5-piecearrangement. Follow the instructions and pictorial view below to make the5-piececonnections.

Enhanced Surround Sound Operation (See Figure 1)

1)Connect the left and right satellite speakers.

Notice that the DIN connectors from the left and right satellite speakers are color-codedand plug into the matching color indicators on the back of the subwoofer. Also note that the connectors have arrows. These arrows should face up as shown in Figure 1.

2)Connect the left and right surround speakers.

The left (yellow) and right (purple) surround speaker connectors are plugged into the corresponding colored inputs on the back of the subwoofer.

3)Connect the subwoofer to the computer.

The green color-codedwire connects the ANALOG INPUT on the subwoofer to the AUDIO OUTPUT on the computer. The black RCA type plug is used to connect the S/PDIF INPUT on the subwoofer to a DVD player.

4)Plug the AC power plug into the wall outlet.

The ADA880 unit should be installed close to the AC power outlet so that the power plug can be readily removed from the outlet in the event of a hazardous problem.

Your ADA880 system is now ready for use.

Figure 1

Near Field Stereo/Surround Sound Operation (see Figures 2 and 3)

If it is desired to convert to a 3-speakersystem, 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 2)

2)Remove the left (yellow) 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 2.

(The connections to the satellite speakers are made automatically once the surround speakers are mounted)

The ADA880 unit should be installed close to the AC power outlet so that the power plug can be readily removed from the outlet in the event of a hazardous problem.

Your ADA880 system is now ready for use.

Figure 3

Placement of Speakers (See Figures 4 and 5)

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

The satellite and surround speakers are magnetically shielded and can be placed close to the computer monitor without distorting video images. Best stereo effect is obtained by placing the speakers as far apart as practical.

Enhanced Surround Sound

Best surround effect is obtained by placing the surround speakers forward of the monitor and approximately the same distance apart as the satellite speakers. Excellent results are obtained when the surround speakers are in line with, and slightly above the listeners ears.

*Note: Care should be taken not to place diskettes or other magnetic media on the subwoofer.

Using the Speaker System (See Figure 6)

*POWER. Press this button to turn power on. A green indicator will glow. Press again to turn power off.

DOLBY. The DOLBY button allows 2 modes of operation – STEREO or SURROUND. Repeatedly pressing this button toggles between the two modes.

See A) B) C) below.

A)STEREO. When the function indicator is off: the unit is in the STEREO mode.

B)SURROUND. When the function indication is amber the unit is in the SURROUND PRO-LOGICmode.

C)DOLBY DIGITAL (AC3). When the function indicator is green: The unit is in the DOLBY DIGITAL (AC3) mode. This function is selected automatically whenever a Dolby Digital Surround Signal is detected at the input. The automatic selection will occur regardless of the mode of operation, STEREO or SURROUND.

*Note: If the AC source of power is turned off before the power switch is turned off on the unit a “pop” sound may be heard from the speakers. This is normal and not a problem. To avoid the “pop” sound, turn off the unit first.

BASS. The BASS button allows 2 modes of operation: BASS level control or CENTER level control. See D) and E) below.

D)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 green function indicator above the control will glow. Also, the volume level indicators will glow showing the last setting of the control. Rotate the master volume control clockwise to increase bass and counter clockwise to decrease bass. Only 6 of the 7 level indicators are operational in this mode. As volume is increased/decreased

only one level indicator at a time will glow in ascending or descending order. As the volume control is varied and passes through the flat response setting of the control, the 2 center indicators will glow. (This is the equivalent of a manual volume control set at center detent indicating flat response.)

E)CENTER LEVEL MODE. This function is only operational in the SURROUND mode. Hold the BASS button depressed until the function indicator begins flashing on/off. Rotate the master volume control clockwise to increase the center volume and counterclockwise to decrease center volume. The green volume level indicators will glow in ascending order as volume is increased and will turn off in descending order as volume is decreased.

TREBLE. The TREBLE button allows 2 modes of operation, TREBLE level control or SURROUND level control. See F) and G) below.

F)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 green function indicator above the control will glow. Also, the volume level indicators will glow showing the last setting of the control. Rotate the master volume control clockwise to increase treble and counter clockwise to decrease treble. Only 6 of the 7 volume level indicators are operational in this mode. As volume is increased/decreased only one level indicator at a time will glow in ascending or descending order. As the volume control

is varied and passes through the flat response setting of the control the 2 center indicators will glow. (This is the equivalent of a manual volume control set at center detent indicating flat response.)

G)SURROUND. This function is only operational in the SURROUND mode. Hold the TREBLE button depressed until the function indicators begin flashing on/off. Rotate the master volume control clockwise to increase the surround volume and counter-clockwiseto decrease the surround volume. The green volume indicators will glow in ascending order as volume is increased and will turn off in descending order as volume is decreased.

MASTER VOLUME CONTROL. The MASTER VOLUME CONTROL provides two 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 is not adjusted within a few seconds, the control reverts back to becoming a master volume control.

FLAT RESPONSE SETTINGS. 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. Initially the function indicators above buttons the will be green. The buttons must be kept depressed until the indicators turn off. The amplifier response is now flat (linear). If it is desired to increase/decrease BASS or TREBLE response press either of these buttons respectively. Two volume level indicators will glow in the middle of the display indicating the flat response of the amplifier. Notice that the volume level display has changed from 7 to 6 indicators. Rotate the volume control clockwise to increase levels andcounter-clockwiseto decrease levels from the flat setting.

To access CENTER and SURROUND volume level settings, the unit must be in the SURROUND mode. Press either the BASS or TREBLE button until the function indicator flashes. Four volume level indicators will glow showing mid setting. Adjust the volume control clockwise to increase volume level from the mid setting and counter-clockwiseto decrease volume level from the mid setting. All volume level indicators are operational in this mode.
