THX subwoofers
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" 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.
