Dual Subwoofer Connections
When hooking up a stereo pair of subwoofers, wiring is quite similar to traditional
high-level
connections. Here, instead of running both speaker cables from your
receiver or amplifier to the left and right high-level terminals on the subwoofer,
you will run the left channel to the left channel subwoofer and the right channel to
the right channel subwoofer. Again, take care to make red to red (+) and black to
black (-) terminal connections.
Don't worry that on your left'subwoofer the right channel terminals will be empty
and that on the right channel subwoofer the left channel terminals will be empty-
both channels are combined at the subwoofer's input stage. There is a possibility
that
with this type of wiring you may need to increase your gain a little bit for
proper balance.
A
stereo subwoofer system using low-level connections is equally simple. From
your receiver or preamp, run an RCA-type interconnect from the left channel main
output to the left channel low-level input on the subwoofer you are using for the
left channel. The process should then be repeated for the right channel. In this
setup, main speaker connections are made between your receiver or amplifier in a
traditional
manner. If you are using dual subwoofers with a Dolby Digital System,
we suggest that each subwoofer receives its appropriate left or right channel signal,
plus an LFE signal (with the LFE plugged into the LFE input). You would then set
the Dolby Digital processor's bass management system to "Large" left and right
main speakers and sub to "Yes."
Operating Controls
Your Definitive Technology SuperCube subwoofer is equipped with a full
complement of operating controls to ensure complete flexibility and maximum
performance in any installation. Most of them basically are the "set and forget"
type, although occasionally certain controls will require minor adjustments.
Gain Control
On the back panel of your subwoofer is a gain (volume) control. This control is
used to raise or lower the output level of your subwoofer in relation to the other
speakers in your system.
Low Pass Filter
Your subwoofer's back panel features a continuously variable low pass filter.
This filter is continuously variable between 40 and 150 Hz. It rolls off the high-
frequency response of your subwoofer. This low pass filter control is used to obtain
the optimum transition between the subwoofer and your main speakers. We receive
many questions from subwoofer owners asking us where to set the filter controls in
