THX subwoofers page 5 To connect the subwoofer, run a shielded RCA - RCA interconnect cable from the SUBWOOFER OUTPUT jack on your THX controller to the "LEFT/MONO" "INPUT" jack on the subwoofer's backplate. See Figure 1 below.

TESTING THE SUBWOOFER (THX MODE) Once all of the interconnect cables are in place, you are just about ready to plug in the subwoofer. Set the "LOW PASS FILTER" toggle switch to the "THX MODE" position.
THX subwoofers page 7 and it gives you maximum output level, dynamic range, and headroom. In your listening room, the "ANECHOIC" position will actually produce a rising output below about 30 Hz. Its response is not as flat (accurate) as the "THX" position and it limits the subwoofer's maximum output and dynamic range.

page 10 THX subwoofers WIRING WITH THE M&K HP-80 OR VF-80 HIGH-PASS FILTERS (NON-THX ) The M& K HP-80 and VF-80 High-Pass Filters can improve the sound of systems by filtering the bass fed to the main amp and Satellite speakers. These filters will give your system greater dynamic range, lower distortion, and an increased maximum output.
THX subwoofers page 11 to feed these filters. To connect one of these filters, run one set of shielded RCA - RCA interconnect cables from the receiver, amp or preamp's MAIN OUTPUT to the input jacks on the HP-80 or VF-80.
page 12 THX subwoofers an additional total of 6 dB of output. Wiring with two subwoofers is simple. Instead of running two interconnect cables to one subwoofer, just run one interconnect to each subwoofer, using the "LEFT/MONO INPUT" jack on each subwoofer.

page 14 THX subwoofers Buzzes and rattles can be cured or improved by applying glue, tape, or pads in the area where the objects are vibrating against each other. Try felt pads between objects that cannot be taped or glued together (such as picture frames buzzing against walls).
