2. INTRODUCTION Congratulations! Y ou 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&K VX-series powered subwoofer will thrill and excite you.
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.
This will give you better bass quality than using the speaker inputs, because it bypasses your amp or receiver's amplifier stage. T o connect the subwoofer in this way , simply run one or a pair .
USING SPEAKER WIRE CONNECTIONS Some M&K subwoofer owners hook up their subwoofer by connecting it to their receiver or amplifier using speaker wires. T o do so, you make the same kind of connections that you would use for your satellite (or main) speakers, except that both the left and right channels go to the subwoofer .
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 of speaker wires to the same output terminals.
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.
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. T o 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: Y our subwoofer has a protection circuit that protects it from overheating. After hours of continuous operation at extremely high volume levels, this circuit may cut off the power to the subwoofer .
and 5:00 PM Pacific T ime, Monday through Friday , at (818) 701-7010. If you call outside these hours, leave a message, and we will return your call. Alternatively , an e-mail can be sent to service@mksound.
3. If multiple subwoofers are used, place them in the same location. Stacking is best, but you can also put them side by side. Another option for multiple subwoofers is to place them in different locations. This is appropriate when you have limited choices in locating the subwoofer and none of the available locations work well.
3. T urn off all limiters and compressors, auto azimuth controls, auto balance controls, etc. 4. If the processor/receiver/receiver has an input level control, calibrate it per the manufacturer ’ s instructions.
