MILLER & KREISEL SOUND* Model VX-7 MARK II ( V Series Subwoofer )

Description: NOTE: Once you have achieved a rough subwoofer level setting, refer to the system set-up guide found later in this manual. NOTE: When your subwoofer is switched to the “AUTO ON” position, it will use a slight amount of electricity when in Standby. If you are concerned about power usage, you may want to switch the subwoofer off instead. Switching the unit off is also a good idea if you know that you will not be using it for some time. 5. WHERE TO PLACE YOUR SUBWOOFER M&K Sound subwoofers perform well in most room locations. With a properly tuned speaker system, you should hear deep bass coming from the front of your system as if your satellites and subwoofer were one big system rather than separate speakers. One proven way to find the best location for your subwoofer is to first place the subwoofer at the listening position. Run music with good bass content through it and then go over to the area where you believe the final subwoofer placement will be. Listen to how the room reacts to deep bass being played. As you walk around that area, you should find places where the bass sounds deep and well defined and places where the bass sounds weak and less well defined. The place where you hear the tightest bass with the most impact is probably the best location for your subwoofer. We recommend that you place your subwoofer as close to a solid wall as possible. Avoid placing your subwoofer farther than a few inches away from any wall surface as the reflected sound from the wall will interfere with the direct sound coming /from the subwoofer and create phase anomalies that will be destructive to good bass performance. Also try to avoid corners that are near doorways or openings. Sometimes the best sound results from aiming the subwoofer’s drivers directly into the wall (1” to 2” away from the wall itself.) If you are using multiple subwoofers, sometimes putting them in the same location provides the best solution. Stacking them is also a possible solution or you could place them side-by-side. Alternatively, when using multiple subwoofers, you could try placing them in different locations. This may be appropriate when you have limited choices for placement and none of the available locations seem to work well. Try to place your subwoofers at equal distances from the listening position to avoid phase problems. Ultimately, the amount and quality of deep bass you get in your room are dependent on the room itself. Low frequency sounds are affected most by the size of the room and construction used to build it. All rooms are different when it comes to reproducing bass, and in any given room, bass quality and quantity change when the subwoofer is moved from one location to another. In some rooms, a corner location may excite resonance modes resulting in a muddy or boomy sound. In this situation, a more central location along a wall, away from a corner may give better results. It’s a good idea to experiment with your subwoofer location or locations. Try to find a placement or placements that provide an overall sound that is powerful and well defined throughout the audio bandwidth, where no one bass note or notes overpower others. Because the subwoofer generates so much sonic energy, its output may cause objects in and around the listening room to vibrate. If this occurs in your room, you may need to damp the vibration of these objects. One subwoofer is usually sufficient in a two-channel stereo system for the same reason that one subwoofer works well with multi-channel systems. Our ear-brain hearing physiology is unable to locate the direction of low frequencies 7 below approximately 80 Hz. The directionality of low frequency sounds (bass drums, bass instruments, etc.) is determined by the higher frequency overtones and harmonics that are reproduced by the satellite speakers. Some people believe that we can determine directionality from frequencies down to 60 Hz. In any case, M&K Sound satellite speakers are tuned to crossover to an M&K Sound subwoofer at 80 Hz. This is also the Dolby Laboratory and THX specification. No matter where you place your subwoofer, you must allow room for ventilation of its heat sink and back plate. The subwoofer’s power amplifier is mounted on the back plate and it generates heat. Please observe the following: 1. Leave adequate clearance around the subwoofer’s heat sink. Do not cover it with drapes or close it up in an unventilated cabinet. 2. Do not place the subwoofer near baseboard heaters or forced air heating outlets. 3. Do not use your subwoofer outdoors or in an overly humid environment. 4. Do not plug the subwoofer into an AC outlet until all system wiring is complete. 6. USE OF THE PHASE CONTROL M&K Sound V8 & V12 subwoofers feature a phase control variable from 0 to180 degrees. This control can help you to fine-tune the transition between sound sent to your main speakers and your subwoofer. In order to optimize the integration of your subwoofer with your main speakers, you should perform a phase test. This test will help you to achieve a seamless transition between your main speakers and subwoofer(s). A phase test is helpful, because when satellite (or main) speakers are located in a different location from the subwoofer, each speaker is located at a different distance to the listener. Even small differences in distance mean that the arrival times of sound from the various speakers to the listener are also different. These time differences can cause phase anomalies, which are destructive to the reproduction of sound in your room. Be sure to re-do this test if you move your speakers. To begin, select something to play through your speakers that you are familiar with. A stereo CD is a good choice since surround sound material with its complexity can make this test more difficult. While playing the CD through your left and right front speakers along with your subwoofer, listen to the mid-bass region (70 - 100 Hz) – that part of the audio spectrum where instruments like bass and drums need both the satellites and subwoofer for accurate reproduction. Adjust the phase control or switch from 0 degrees to 180 degrees. Note the difference between the two settings. If you hear a tighter, more defined quality to the sound with better low bass reproduction with one of these options, then that is probably the best setting. If you are using two or more subwoofers, perform this test with each subwoofer individually with the others turned off. When you hear the best balance between stereo image localization, maximum low bass impact and well defined output in the mid-bass, you have found the correct setting. If you hear little or no difference when adjusting the phase control knob or phase switch, set it to the 0 degree (default) position. 8 A more accurate method of establishing the phase relationship between your satellites and subwoofer or subwoofers is to use a pink noise generator and a spectrum analyzer. Place the microphone at the listening position and run pink noise through the system. Take note of the mid-bass region (70 - 100 Hz) on the analyzer’s display. The setting that shows the most output in that region and also shows the best low bass response has the correct phase. 7. CROSSOVER BYPASS SETTING All current Home Theater receivers and processors provide the necessary high-pass and low-pass filtering (bass management) to ensure proper integration of satellite/subwoofer speaker systems. When using your subwoofer with one of these components it is recommended to set the “CROSSOVER CONTROL” on the back of the subwoofer to the “BYPASS” position. This leaves the full control for crossover settings to the handled by the receiver/processor build in bass management functions, and will in most setups provide the best integration between satellite/subwoofer. When connecting THX certified subwoofers, the crossover control “BYPASS” position will be marked “THX” to directly indicate the correct setting. The bass management section in THX certified receivers and processors are optimized in their filter design to make smooth and easy integration between subs and satellites speakers. It is recommended to carefully studying your receiver or processor manual for speaker setup, as correct settings is important to achieve best possible sound. 8. CROSSOVER CONTROL If your receiver or processor does not have an internal crossover, you can use the “CROSSOVER CONTROL” to variable set the upper roll-off point of the subwoofer to match your satellites. The control of fine-tuning the transition of sound between satellites and subwoofer is defined to set “CROSSOVER CONTROL” to 80 Hz when using larger main speakers, and 110 Hz when using smaller satellite speakers. The overall system is expected to reproduce frequencies at the entire bandwidth, but as the subwoofer will be rolling off above the crossover point, it is therefore recommended to look at the main speakers or satellite speaker’s
