headphones are connected, all speakers are muted.
USE OF CONTROLS
POWER ON/OFF:
The Power On/Off button is located on the System Controller. Press the
POWER button to turn on the speaker system. Push it again to turn the
unit off. One of the Mode LEDs will glow to show power is on.
MASTER VOLUME CONTROL:
Locate the rotary knob on the System Controller. The rotary knob acts as
the Master Volume control and has several functions. It operates as a
Master Volume control for the overall system when no other buttons have
been pushed. It is also 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
seconds, the control reverts back to Master Volume control function.
Five level indicators around the rotary knob show the position of the
control. In the extreme counterclockwise 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, when all LED's are glowing.
If one of the functions buttons has been depressed (Bass, Treble or Mode),
the master level rotary control will adjust the level of the function selected.
The green function indicator associated with the function selected will be
illuminated. See Treble/Bass Selectors below.
TREBLE/BASS SELECTORS:
Bass and Treble selectors are located on the System Controller. When the Bass
button is pushed, the Bass LED will turn on and the rotary knob will change the
level of bass on all Satellites, having the greatest effect on the Subwoofer. The
LEDs around the rotary knob will light one at a time to indicate the level of bass
boost or reduction. The center LED indicates the default position. Pushing the
Bass button again will immediately exit this function. The default bass level is at
the center LED position. To reset the bass level to the default position, hold the
Bass button down for three seconds.
Pushing the Treble button will result in a similar pattern. When the Treble
button is pushed, the Treble LED will turn on and the rotary knob will change
the level of treble on all Satellites. The LEDs around the rotary knob will
light one at a time to indicate the level of treble boost or reduction. The
center LED indicates the default position. Pushing the Treble button again
will immediately exit this function. The default treble level is at the center
LED position. To reset the treble level to the default position, hold the
Treble button down for three seconds.
MODE SELECTOR:
The Mode Selector button is located on the System Controller. The Mode
Selector changes the operation of the system from one mode to the next:
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 (system default) 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 Satellites, 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 Satellites, in either the Stereo x2 or
Gaming mode, hold down the Mode button for approximately 3 seconds.
The left-most LED around the Master Volume Control (rotary knob) will then
begin flashing, indicating that the Master Volume control is now programmed
to adjust the level of the Rear Satellites. The LEDs around the rotary knob
will light one at a time to indicate the strength of Rear speaker level. Pushing
the mode button again will immediately exit this function. If the control is not
actively used for a short while, the control reverts back to Master Volume
control function.
Since there is no rear output in Stereo Mode, there is no rear volume level
adjustment in this mode. The default Rear Satellite speaker level is at the
center LED position.
The rotary knob reverts to Master Volume control function when a period
of 3 seconds of inactivity occurs after adjusting the Bass, Treble, or Rear
speaker levels.
SYSTEM RESET TO FACTORY DEFAULT SETTINGS:
To return to factory default settings, press both the Bass and Treble
buttons at the same time and hold them down for about 3 seconds. This
will reset the bass, treble, mode, volume and rear volume settings.
PLACEMENT OF SPEAKERS
All stereo information is heard from the Satellite speakers. The Subwoofer
contains no stereo information and 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
the wall or corner of a room provides maximum bass efficiency.
WARNING: The Subwoofer is not magnetically shielded. The Subwoofer
should NOT be placed near video display devices such as a TV or
computer monitor. The Subwoofer should NOT be placed near computer
hard drives. Position the Subwoofer at least 2 feet (0.6m) away from
computer hard drives, or any other media that uses magnetic encoding.
The Satellite speakers are magnetically shielded and can be placed close
to a video display (TV, computer monitor) without distorting the video
image. 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 Satellites can be placed slightly behind the listener.
Usually best stereo effect is obtained by placing speakers as far apart as
their wiring allows. Try using this same principle if the wall-mount option is
utilized for the Rear Satellites. Front Satellite and Rear Satellites are
usually placed at ear level or slightly above.
Sound effects may vary depending on how the recordings are made.
Therefore, it is not unusual to rearrange the speakers from time to time
until the listener finds which arrangement gives the best results.
