OPERATION OF THE "BASS LEVEL" SWITCH

When using the subwoofer with a non-THX processor, preamp, etc., this switch should be set to the "VARIABLE" position. The subwoofer level can then be set independently to match your speakers. The "CALIBRATED" mark is a reference relative to THX levels. For a discussion of this "CALIBRATED" mark, please see "OPERATION OF THE BASS LEVEL SWITCH (THX)" on page 7.

WIRING WITH A NON-THX PROCESSOR OR PREAMP

The "FROM PREAMP" RCA terminals on the subwoofer allow you to connect the subwoofer to preamp-level components other than THX controllers, such as preamplifiers, integrated amps and receivers with preamp outputs, high-pass filters, crossovers, standard surround sound processors, etc. All of the input connections and controls for the subwoofer are located on its large metal backplate, which can be found on the back panel of the subwoofer cabinet.

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 5 on page 10.

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.
