FIGURE 5 - WIRING ONE SUBWOOFER TO AN AMP
OR PREAMP WITH ONE SET OF PREAMP OUTPUTS
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 above. If you have a surround sound processor with a SUBWOOFER
OUTPUT jack, use it to feed the subwoofer. See Figure 3 on page 8.
Some surround processors/receivers/amps have very low output levels from their SUBWOOFER
OUTPUT jacks. If you do not get enough bass when using the SUBWOOFER OUTPUT jacks on a
non-THX processor, use that processor's PREAMP OUTPUT jacks instead. See Figure 5 above.
