Computer gaming sounds cards have three outputs. Most
usually, the outputs will be marked as Digital output,
Front output and Surround output. Some slightly
different terminology may be used. However, the sound
card instructions will provide information so that you
can determine what the outputs are. Connect the ACS56
three inputs to the computer sound card.
Stereo Operation. If your computer only has a stereo
sound card, the ACS56 will still provide excellent
performance. In this instance the sound card stereo
output should be connected to the Front speaker input.
Both Front/Surround speakers will be operational. The
front and surround speakers in the left channel will
perform as the left surround stereo channel and the
right front and rear speakers will be the stereo right
channel. The mode button should be in stereo function.
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
rear of the right satellite speaker. Press this switch to
turn the unit on, the Mode indicator will light to show
power is on. Press the switch again to turn power off.
Operation any of the functions will also turn the unit on.
In this instance, to turn the unit off, press the On/Off
switch.
Master Volume Control. The master volume control
has several functions. It operates as a master volume
control for the overall system and can be used to
individually adjust the levels of Bass, Treble, or
Surround sound. If any of these functions is selected and
not used for a few seconds, the control reverts back to
becoming a master volume control.
Seven level indicators around the control show the
position of the control. In the extreme counter-clock
position all LEDs are off. As the control is rotated
clockwise the LEDs illuminate one at a time until in the
maximum position, all LEDs are on.
If one of the functions buttons has been depre ssed (BASS
8
or TREBLE), the master level rotary control will adjust
the the level of the function selected. In this mode, the green
function indicator associated with the function 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 each 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 factory 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 LED indicator above the Mode
switch can operate in two colors, Green and Amber. By
pressing the Mode switch repeatedly, the mode of
operation can change from
to the "Gaming" mode. When the LED is green the
ACS56 is
the Gaming mode and when the LED is amber, the unit is
in the stereo mode.
Surround Channel Volume Level Adjustments.
To adjust the volume level of the surround speakers, in
either the stereo or gaming mode, hold down the Mode
button until the level indi-cators around the Master
Volume Control flash On/Off. The flashing LEDs indicate
that the master volume control is programmed 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.
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 surround speakers can be
placed slightly behind the listener or as far as the
speaker cords allow. Most usually the speakers are
placed at ear level or slightly above. The surround
speaker stands contain notches for mounting the
surround speakers to a wall with screws, if desired.
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.

Introduction
L'ACS56 est un système de haut-parleurs
amplificateurs spécial « jeux vidéo ». Les signaux
d'entrée qui excitent les haut-parleurs sont fournis par
un ordinateur multimédia à l'aide d'une carte sonore de
jeu. L'ACS56 peut également fonctionner à partir d'une
carte de son stéréo, mais dans ce cas, seules les
opérations stéréophoniques des haut-parleurs sont
possibles.
L'ACS56 comprend quatre haut-parleurs satellites et
un caisson d'extrêmes graves (subwoofer). Les haut-
parleurs satellites sont protégés par un blindage
antimagnétique ; ils peuvent donc être placés à
proximité d'un moniteur sans entraîner de distorsion de
couleurs ou d'images. Le subwoofer n'est pas doté d'une
protection antimagnétique ; il ne doit pas être placé à
proximité d'un moniteur.
Tous les sons ambiophoniques et stéréophoniques sont
diffusés des haut-parleurs satellites. Les subwoofers
présentent des fréquences monoauriculaires, qui ne
contiennent pas d'informations stéréophoniques ou
