Setup Instructions; Placement Of Speakers - Altec Lansing ATP4 Setup Instructions

INTRODUCTION
The ATP4 is an amplified speaker system especially designed for
"Gaming." The input signals to the speakers are received from the gam-
ing sound card of a multimedia computer. The ATP4 can also operate
from a stereo sound card; however, in this instance, only stereo opera-
tion of the speakers is possible.
The ATP4 consists of four satellite speakers and a subwoofer. The
satellite speakers are magnetically shielded and can be placed close to
the computer monitor without distorting color or images. The subwoofer
is not magnetically shielded and should not be placed close to the mon-
itor.
All stereo and surround sound is processed from the satellite speakers.
Subwoofer frequencies are monaural and contain no stereo or surround
information. As a result, the subwoofer does not have to be placed in
any particular relationship to the satellite speakers. The subwoofer is
not magnetically shielded and should not be placed near the monitor.
Placing the subwoofer on the floor close to a wall, corner of a room or
under a desk gives excellent results. Figure 1 shows a typical arrange-
ment of the speakers for best stereo and spatial affects.

SETUP INSTRUCTIONS

(SEE FIGURE 2)
Do not insert the power plug into an AC outlet until all connections are
made.
Notice that the input jacks on the subwoofer are color coded to prevent
errors. The plugs that are inserted into these jacks have matching col-
ors. As an example, the left front speaker satellite has a brown connect-
ing plug. The plug is inserted into the left front jack with the brown color
strip marking. All other connections are made in the same way. A DIN
plug is used to make the connections for the right front satellite speaker.
Note that the DIN plug has an arrow. The arrow should face up for easy
insertion into the DIN jack.
Computer gaming sound cards have two outputs. Most usually, the
outputs will be marked as Front Output and Rear Output. Some slightly
different terminology may be used depending on the manufacturer.
However, the sound card instructions will provide information so that you
can determine what the outputs are. Connect the ATP4 inputs as
required to the computer sound card.
Stereo Operation. If your computer only has a stereo sound card, the
ATP4 will still provide excellent performance. In this instance the sound
card stereo output should be connected to the front speaker input.
There are two modes of operation for stereo input: Stereo and Stereo
x2. In Stereo mode, only the front speakers and the subwoofer are
operational. In Stereo x2 mode, both front and rear speakers are oper-
ational. The front and rear speakers in the left channel will perform as
the left stereo channel and the right front and rear speakers will be the
stereo right channel.
Insert the power plug into an AC outlet. The unit is now ready to be
operational.
OPERATION OF THE CONTROLS
(SEE FIGURE 3)
On/Off Switch. The on/off switch is located on the front of the right
satellite speaker. Press this switch to turn the unit on; the Mode indica-
tor will light to show power is on. Press the switch again to turn power
off.
Master Volume Control. The master volume control has several func-
tions. It operates as a master volume control for the overall system and
can be used to individually adjust the levels of Bass, Treble, or Rear
sound. If any of these functions is selected and not used for a few sec-
onds, the control reverts back to becoming a master volume control.
Five level indicators around the control show the position of the control.
In the extreme counter-clock position, all LED' s are off. As the control is
rotated clockwise the LED' s illuminate one at a time until in the maxi-
mum position, all LED' s are on.
If one of the function buttons has been depressed (BASS or TREBLE),
the master level rotary control will adjust the level of the function select-
ed. In this mode, the green function indicator associated with the func-
tion will be illuminated: see TREBLE/BASS CONTROLS below.
Treble/Bass Controls. To raise or lower the treble or bass response,
press the switch next to the mode selector; a green indicator will glow to
show the function is operational. Turn the ROTARY control clockwise to
increase response and counterclockwise to decrease response. Once
the level is set, the indicator next to the function will turn off after a short
period. Each function can be turned off quickly by pressing the function
button a second time. To reset the Treble and Bass controls to the fac-
tory preset (flat) position, depress and hold the corresponding button for
a period of approximately three seconds. The green indicator will go
out denoting the control has been reset. Once the green indicator is off,
the master volume control becomes operational.
Mode Selector. The mode selector changes the operation of the system
between the three modes of Stereo, Stereo x2, and Gaming. Pressing
the mode button cycles through the three modes. In Stereo mode, the
front input plays on the front satellites and the subwoofer. In Stereo x2
mode the front input plays on both the front and the rear satellites and
the subwoofer. In Gaming mode, the front input plays on the front satel-
lites, the rear input plays on the rear satellites, and the subwoofer plays
from both the front and the rear inputs.
Rear Volume Level Adjustments. To adjust the volume level of the rear
speakers, in either the Stereo x2 or Gaming mode, hold down the Mode
button until the left-most LED around the Master Volume Control flash-
es. This flashing LED indicates that the master volume control is pro-
grammed to adjust the level of the rear speakers. If the control is not
actively used for a short while, the control reverts back to becoming a
master volume control. Since there is no rear output in Stereo Mode,
there is no rear volume level adjustment in this mode.
Phase Switch (See Figure 2). This switch is for use in Gaming mode
only. It allows the user to obtain the best possible output with whatever
sound card may be used with gaming output. When the system is set
up, the user can listen to the system output and decide which position
(out or in) is best for the application. If the system lacks bass response,
try reversing the switch.
System Reset. To reset the system to the default setting, press both the
bass and treble buttons simultaneously and hold down for about 3 sec-
onds. This will reset the bass, treble, mode, volume and rear volume
settings to the factory default settings.

PLACEMENT OF SPEAKERS

Some experimentation may be required to obtain the best sound effects
in your particular room environment. The subwoofer achieves maximum
efficiency when placed on the floor and close to a wall or corner of a
room. In this instance the walls behave as an extension of a speaker
horn. The subwoofer is not shielded and should not be placed near the
monitor. The front satellites can be close to the monitor or stretched out
as far as the speaker cords allow. The placement depends on where the
listener sits. The rear speakers can be placed slightly behind the listen-
er or as far as the speaker cords allow. Most usually the speakers are
placed at ear level or slightly above. Sound effects may vary depending
on how the recordings are made. By re-arranging the speakers from
time to time the listener will become aware which arrangement gives
best results.
