or
i2 ) My sound card has 2 STEREO LINE OUTPUTS
(4-channel): For sound cards with a 4-channel
gaming configuration, use your unified stereo cable
(see part illustration in appendix). Connect the green
and purple end of the unified stereo cable to the
green and purple inputs at the subwoofer (these are
labeled "Front" and "Rear" respectively on the back of
the subwoofer). On the opposite end of the unified
stereo cable, connect the green plug to the sound
card's front output (normally labeled "1", "front" or
green), and the black plug to the sound card's rear
output (normally labeled "2", "rear" or black). You will
not need your digital RCA cable for this setup.
or
i3 ) My sound card has 2 STEREO LINE OUTS and
a DIGITAL (S/PDIF) OUT: For sound cards with 2
stereo outputs and an added digital output on the
same card, use the unified stereo cable supplied
(see part illustration in appendix) and connect the
purple end of the unified stereo cable to the
subwoofer's "Rear Analog Input". Connect the
opposite black end of the unified stereo cable to the
sound card's rear output (normally labeled "2", "rear"
or black). You will not need to use either of the green
ends with this setup. Next, using your digital RCA
cable (see part illustration in appendix), connect one
of the black ends to the subwoofer's "Digital Input".
The opposite end of this digital RCA cable should
plug into your sound card's digital S/PDIF output.
NOTE: It may be necessary to use the RCA-to-
phono adapter (see part illustration in appendix) if
your card's digital output is a phono jack instead of a
coaxial.
h ) Connect the system's control pod cable
(blue) to the "Control" jack (also blue) on the
back of the subwoofer.
STOP: For step 'i' you will need
to carefully identify which type of
sound card setup you have:
i1 ,
i2 , i3 or i4.
i1 ) My sound card has 1 ANALOG OUT-
PUT: Using your unified stereo cable (see
part illustration in appendix), plug the green
end into the subwoofer's "Front Analog Input",
and the opposite green end into the sound
card's single audio output. You will not need
the digital RCA cable or the purple and black
ends of the unified cable for this setup.
SPECIAL FEATURE: When operating as a
3-piece (or front channel input only), the
system has the ability to create a Virtualized
Dolby Surround effect; use Surround Vol.
