POWERED SUBWOOFER
FIGURE 4 -WIRING TWO SUBWOOFERS TO AN AMP OR PROCESSOR
WITH A SUBWOOFER OUTPUT JACK (NON-THX)
If your surround processor has only one PREAMP OUTPUT (and no SUBWOOFER OUT), and you
do not have an M&K High-Pass Filter or crossover, you must use a Y-connector to feed the amplifier
and subwoofer. See Figure 5 on page 10. If you have a surround sound processor with a
SUBWOOFER OUTPUT jack, use it to feed the subwoofer. See Figure 3 above.
If you are using two subwoofers, it is not necessary to use both inputs on each subwoofer. Connect
the interconnect cable to the LEFT/MONO "INPUT jack only. Run the Left channel interconnect cable
to the Left subwoofer and the Right interconnect cable to the Right subwoofer. See Figure 4.
Some surround processors/receivers/amps have very low output levels from their SUBWOOFER
OUTPUT jacks. If you do not get enough bass using the SUBWOOFER OUTPUT jacks on a non-THX
processor, use that processor's PREAMP OUTPUT jacks instead. To connect the subwoofer, run
shielded RCA - RCA interconnect cables from the outputs on your component to the "INPUT" jacks
found on the subwoofer's backplate. See Figure 5 on page 10.
If your processor has a single subwoofer output, do not use a Y-connector to connect it to both the
Left and Right input terminals of the subwoofer. The subwoofer combines both channels to mono in
its amplifier input stage.
