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 subw[...]

page 6 THX subwoofers 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" position and the "BASS LEVEL" toggle switch to the "THX" position. Set the "SUBWOOFER PHASE"[...]

THX subwoofers page 7 For the V-125 THX , the "CALIBRATED" level is 4 dB lower than the "THX" level (switch set to "THX"). Set the control to this mark if you have only one subwoofer in the system (such as in a very small room). On both the MX-150 THX and V-125 THX , the +2 and +4 marks indicate the points where your s[...]

page 8 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 d[...]

THX subwoofers page 9 FIGURE 5 - WIRING ONE SUBWOOFER TO AN AMP OR PREAMP WITH ONE SET OF PREAMP OUTPUTS 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 surroun[...]

page 10 THX subwoofers To connect the subwoofer, run shielded RCA - RCA interconnect cables from the outputs on your component to the "INPUT" jacks found on the subwoofer's backplate. See Figure 5 on page 9. If your processor has a single subwoofer output, do not use a Y-connector to connect it to both the Left and Right input termin[...]

THX subwoofers page 11 DO NOT PLUG THE SUBWOOFER INTO A SWITCHED OUTLET ON ANOTHER COMPONENT. THE SUBWOOFER CAN DRAW UP TO 400 WATTS FROM THE AC LINE. IT MUST BE PLUGGED INTO A SOLID AC LINE. Now, play some music through your system to make sure that the Satellite speakers are working properly. If they are, carefully advance the "BASS LEVEL&qu[...]

page 12 THX subwoofers Here are two methods of setting the correct phase with your subwoofer. PHASING TEST METHOD ONE Set the switch labelled "SUBWOOFER PHASE" to the "+" position. Then, play a familiar CD, LP, laserdisc or tape with steady, consistent bass content. Listen carefully to the "mid-bass" region of 70 - 125[...]

THX subwoofers page 13 The amount and quality of bass you hear is dependent on the room itself. Low frequencies are affected by a room's size and type of construction. Rooms differ when it comes to reproducing bass, and in every room, bass quality changes when the subwoofer is moved from one location to another. A simple rule to remember is th[...]

USE OF SPIKED FEET WITH "MX" SUBW OOFERS If your M&K THX subwoofer is an "MX" push-pull dual driver subwoofer, we have enclosed a hardware kit consisting of four black metal spikes, threaded at one end and tapering to a sharp point at the other. Depending on their orientation, they can be used eithe[...]
