SUBWOOFER SERIES INSTALLATION
This can be a desired setting if you are using the sub in combina-
tion with tower or floor-standing speakers. If you are using satel-
lites speakers with 5.25" cones sizes or under, you will want to
move the frequency up to slightly overlap the lowest frequency the
satellites can produce. If your satellite frequency response is rated
at 80 Hz to 18 kHz then you may choose to move the LPF control
higher to blend the highest frequency of the subwoofer slightly past
the lowest frequency of the satellites. In this example you may wish
to set your sub's LPF control to 90 Hz creating a mid bass coupling
between your sub and the rest of your speaker system.
Balances the loudness of the Subwoofer relative to the Front
speakers and compensates for room effects on the Subwoofer’s
output. It should not be necessary to set the level control to maxi-
mum volume to achieve a well balanced installation, but you may
need to adjust when changing between music CD's and DVDs.
Important: Use Option1 or Option 2, but not both.
OPTION 1. Connection with speaker wire - Connect speaker wires
from the Receiver’s front left and right speaker outputs to the
Subwoofer’s Speaker Level-In connections. Connect left channel to
left input and right channel to right input. You have the option of
connecting your main speakers to the speaker B outputs on your
receiver if it is so equipped; otherwise, you have the option of con-
necting your main speakers using the connections on the
Subwoofer. This will send the audio signal to the main speakers
while funneling the low bass frequencies to the subwoofer. To take
advantage of this option, connect your main speakers to the right
and left outputs on the Subwoofer. Be sure you take care to main-
tain proper signal polarity by connecting the red wire to the red
terminal, and black wire to the black terminal.
OPTION 2. Connection with audio cable - This connection employs
a left/right audio cable. To use this option, your receiver should
include a subwoofer Out jack, which is typical of receivers
equipped with Dolby Digital and DTS 5.1 decoding. Locate the sub-
woofer output jack on the back of your receiver.Using a standard
audio cable, connect the subwoofer output onthe back of your
receiver to the line-In on the back of the subwoofer. The line-out
feature can be used if you choose to install an additional sub-
woofer to your system. The line-out would be connected to the
line-in of the second subwoofer.
