page 4 V-1250THX subwoofer 2. INTRODUCTION Congratulations! Your new M&K THX Select ® subwoofer truly represents the state-of-the-art in subwoofer performance. The new dimension of deep and powerful bass it provides will both thrill and excite you. We strongly encourage you to read this owner's manual, as there is a great deal of informat[...]

V-1250THX subwoofer page 5 Ultimately, the amount and quality of bass you get in your room are dependent on the room itself. Low frequency bass sounds are affected most by the size of the room and the method of construction used to build it. All rooms are different when it comes to reproducing bass, and in any given room, bass quantity and quality [...]

page 6 V-1250THX subwoofer 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[...]

V-1250THX subwoofer page 7 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 to the Left subwoofer and the Right cable to the Right subwoofer. See Figure 2 on Page 6. TESTING THE SUBWOOFER (THX MODE) On[...]

page 8 V-1250THX subwoofer The +2 and +4 marks indicate the points where your subwoofer is producing 2 dB and 4 dB, respectively, more output than the "CALIBRATED" level. SETTING SUBWOOFER LEVEL (THX) The proper method of setting the level of the subwoofer in THX mode is to use the low frequency pink noise test signal generator built into[...]

V-1250THX subwoofer page 9 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. Fo[...]

page 10 V-1250THX subwoofer 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. If your processor has a single subwoofer output, do not use a Y-connector to connect it to both the Left and Right input terminals of the subwoofe[...]

V-1250THX subwoofer page 13 response, as the room modes excited by one woofer are complemented by the presence of the other. Alternately, if you stack two subwoofers, one on top of the other, their outputs will couple and give you an additional total of 6 dB of output. Wiring with two subwoofers is simple. Instead of running two interconnect cables[...]

page 14 V-1250THX subwoofer If you want to experiment, move the main speakers or subwoofer towards or away from your listening position, in small increments. When you hear the best combination of stereo image localization and focus with solid midbass impact and output, you have the ideal location. If you have two subwoofers, perform one test for ea[...]

V-1250THX subwoofer page 15 Because the subwoofer easily reproduces 60 Hz signals (the frequency of hum), it is often blamed for causing hum that originates elsewhere in the system. Always avoid running all speaker wires and RCA interconnect cables near to AC cords and component power supplies. Placing wires and cables close to AC lines often resul[...]
