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 LED’s are off. As the control is rotated
clockwise the LED’s illuminate one at a time until in the
maximum position, all LED’s are on.
If one of the functions buttons has been depressed (BASS
or TREBLE), the master level rotary control will adjust
the level of the function selected. In this mode, the green
Figure 3
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 Stereo to the “Gaming”
mode. When the LED is Green the ACS56 is in 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 indicators 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 sheilded 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.
