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-LOGIC mode.
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.
