POWERED SUBWOOFER 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 changes when the sub- woofer is moved from one location to another. A simple rule to remember is that you get more bass when you move the subwoofer towards a

POWERED SUBWOOFER FIGURE 1 - CONNECTING TO A COMPONENT’S SUBWOOFER OUTPUT SUB / MONO OUT SUBWOOFER REF SURROUND PROCESSOR OR RECEIVER This will give you better bass quality than using the speaker inputs, because it bypasses your amp or receiver's amplifier stage. To connect the subwoofer in this way, simply run one or a pair of shielded RCA - RCA interconnect cables from the output jacks on your component to the "LINE LEVEL" jacks on the Subwoofer's backplate. If you run one cable, connect it

POWERED SUBWOOFER If you don't have a subwoofer output available, check to see if you have preamp outputs on your preamp, amp, or processor to be able to use these inputs. If you have only one set of preamp outputs, use a Y-connector to feed both the amplifier and the subwoofer. See Figure 2. 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 of the subwoofer.

If you choose to do this, connect the amplifier to the "From Amplifier" terminals on the back of the subwoofer and connect the satellite speakers to the "To Speakers" terminals on the back of the subwoofer. For each channel, make sure that the Positive (+) terminal on the amplifier is connected to the Positive (+) "From Amplifier" terminal (and the Negative (-) terminals are connected), and that the Positive

POWERED SUBWOOFER 9. USING MULTIPLE SUBWOOFERS Using two (or more) subwoofers in your system gives you the ultimate in bass performance. You'll hear improved impact and definition, as well as greater output and dynamic range. If multiple subwoofers are used, place them in the same location. Stacking is best, but you can also put them side by side. Alternately, you can put multiple subwoofers in different locations. This is appropriate when you have limited choices in locating the subwoo

Lightly touch the plug at the free end of the cable, while slowly turning the "BASS LEVEL" control clockwise. If you hear noise from the subwoofer when you touch the cable, the subwoofer is functioning. Look elsewhere in your system for the problem. If you hear no noise, contact your dealer or M&K. 6. Make sure that the input cables are

POWERED SUBWOOFER IF YOU NEED TO REPLACE THE EXTERNAL FUSE: Disconnect supply cord before changing fuse. Replace fuse only with same type. Remove the fuse cap and inspect the fuse. Look carefully at the fuse. If the wire filament inside the glass is bro- ken, replace the fuse ONLY with one of the identical size and value. Using a fuse of a larger value will void your war- ranty AND MAY CREATE A FIRE HAZARD. Plug the subwoofer back in. If it does not work, unplug it immediately, and contact

POWERED SUBWOOFER B. Locate the subwoofer. 1. The best place for the subwoofer is the corner with the best structural strength. If the corners are roughly equal in construction, use the corner nearest the listening position. If the listening position is in the front half of the room, place the subwoofer in a front corner. If it is in the back of the room, place the subwoofer in a back corner. If possible, avoid corners near doorways or openings. 2. If you are willing to experiment, another
