MK Sound MX-SERIES, MX-150THX, V-125THX Wiring ONE Subwoofer with a THX Controller

THX subwoofers page 5

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.
