2. INTRODUCTION Congratulations! You have just made perhaps the most exciting and dramatic addition that you could make to your audio or multichannel audio/video system. The new dimension of deep and powerful bass provided by your M&KVX-series powered subwoofer will thrill and excite you. We enc...

Page 5 - WIRING WITH THE RCA JACK INPUTS

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 aredifferent when it comes to reproducing bass, and in any given room, bass...

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 interconnectcables from the output jacks on your component to the "LINE LEVEL"...

Page 7 - USING SPEAKER WIRE CONNECTIONS; Make matching connections for the Right channel. See Figure 3.; SATELLITE SPEAKER WIRING OPTIONS; AMPLIFIER OR RECEIVER; FIGURE 3 - WIRING TO AMP OR RECEIVER USING SPEAKER WIRES

USING SPEAKER WIRE CONNECTIONS Some M&K subwoofer owners hook up their subwoofer by connecting it to their receiver or amplifier using speaker wires. To do so, you make the same kind of connections that you would use for your satellite (or main) speakers, exceptthat both the left and right chann...

If your amplifier has two sets of speaker outputs (e.g., A and B), you can connect the satellites to one set and the subwoofer to the other. But if you get weak or no output when you connect your speaker this way, connect both sets ofspeaker wires to the same output terminals. PLUGGING IN THE SUBWOO...

Page 9 - USING MULTIPLE SUBWOOFERS; impact and definition, as well as greater output and dynamic range.

Play a familiar CD, LP, or tape with steady, consistent bass. Set the “PHASE” control to the 0˚ position. Listen care- fully to the mid-bass (70 - 100 Hz) region — the part of the spectrum where electric or string basses and drums are found.Then, adjust the "PHASE" control to the 180˚ positi...

Page 10 - If your subwoofer has no output:

With two subwoofers, simply run one speaker wire or interconnect to each subwoofer. Because the left and right channel input signals are combined in the subwoofer's input stage, the only thing this changes is amplifier gain. To com-pensate, just set the "BASS LEVEL" control slightly higher. ...

B. If, after operating the woofer at high volume levels for a long time, the woofer cuts out or becomes intermittent: Your subwoofer has a protection circuit that protects it from overheating. After hours of continuousoperation at extremely high volume levels, this circuit may cut off the power to t...
