THX subwoofers
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.
Some THX controllers have a pair of stereo subwoofer outputs, while others have a single mono
output. Your subwoofer is compatible with both types. If your THX controller has stereo subwoofer
outputs, use a stereo shielded cable, connecting it to the LEFT and RIGHT "INPUT" terminals on the
subwoofer. If your THX controller has only a single mono subwoofer output, use a mono cable and
connect it to the subwoofer's "LEFT/MONO" "INPUT" jack. See Figure 1 below.
Do not use a Y-connector to connect the signal to both the LEFT and RIGHT inputs of the
subwoofer. These inputs are summed to mono in the amplifier input stage, and if they are combined,
the result will be too much gain and bass level.

FIGURE 2 - WIRING TWO SUBWOOFERS WITH A THX CONTROLLER
If you have two subwoofers, do not use a Y - connector to feed both inputs on each subwoofer.
Connect the interconnect cable to the LEFT/MONO "INPUT" only. Run the Left interconnect cable
