    SERVICING - Do not attempt to service this product yourself as opening or removing covers, including those over bottom or side speaker drivers, may expose you to dangerous voltage or other hazards. Refer all service to qualified service personnel. DAMAGE REQUIRING SERVICE - Unplug this product from the wall outlet and refer servicing to qualified personnel under the following conditions: When the power-supply cord or plug is damaged.
  • Page 4: Introduction

    Do not plug the Subwoofer into an AC outlet until all system wiring is complete. 4. SUBWOOFER HOOK-UP There are two different ways to connect the Subwoofer to your system. One uses speaker wire, and the other uses interconnect cable with RCA-type jacks.
  • Page 5: Standard Amplifier/Speaker Wire Connections

    Many 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, except that both the left and right channels go to the Subwoofer.
  • Page 6: Satellite Speaker Wiring Option 1

    To use the filter, connect the speaker wire from the left and right channels of your amplifier to the "FROM AMPLIFIER" terminals on the subwoofer. Connect your left and right main speakers to the "TO SPEAKERS (SPEAKER LEVEL HIGH PASS)"...
  • Page 7 Voice (310) 204-2854 Fax (310) 202-8782 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.
  • Page 8: Wiring With The Rca Jack Inputs

    Electronic High-Pass filters, crossovers, etc. Using these inputs gives you better bass quality than using the speaker inputs (it bypasses your amp or receiver's amplifier stage). If you don't have a subwoofer output available, you must have preamp outputs on your preamp, amp, or processor.
  • Page 9: Using Electronic High-Pass Filters

    PLUGGING IN THE SUBWOOFER Once all the speaker wires or preamp interconnect cables are in place, you are ready to plug in the Subwoofer. Set the "BASS LEVEL" control to "MIN". Then plug the AC cord in. You should hear a thump from the Subwoofer.
  • Page 10: Satellite/Subwoofer Phasing Test

    Instead of moving the switch's position, you must reverse the Positive and Negative speaker inputs on the back of BOTH Satellite speakers. Move the lead on the Positive (+) terminal to the Negative (—) terminal, and vice versa. You can also do this at the subwoofer's "TO SPEAKERS"...
  • Page 11: Use Of The "Low Pass Filter" Control

    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.
  • Page 12: Home Theatre Usage

    powered subwoofers A simple rule to remember is that you get more bass when you move the Subwoofer towards any wall or corner. Moving it away from a wall or corner gives you less bass. Remember that the floor also loads the Subwoofer, and that maximum bass is found with the woofer on the floor in a corner.
  • Page 13: Special Installation Notes

    VERY IMPORTANT: When the Subwoofer is connected to the Left and Right amplifier outputs (this means using speaker wires), and the controller is in Pro-Logic mode, the Center channel WIDE/ NORMAL switch MUST be set to the NORMAL mode. If the switch is set to the WIDE mode, the bass content of the Center channel will not be fed to the Subwoofer, and a significant amount of the bass in the material you are listening to will be lost.
  • Page 14: Troubleshooting

    To avoid having its inverted driver exposed in installations where the cabinet is horizontal, the MX-70B has two speaker grills. If your MX-70B has a solid grille over the inverted driver, leave this grille in place.
  • Page 15 Subwoofer every time you turn the system on: Either the preamp, receiver, or surround sound processor is generating the thump, and the Subwoofer is reproducing it. To eliminate this problem, switch to the speaker wire "FROM AMPLIFIER" input terminals.
  • Page 16: Replace External Fuse

    powered subwoofers IF YOU NEED TO REPLACE THE EXTERNAL FUSE: Disconnect supply cord before changing fuse. Replace fuse only with same type. Remove the fuse cap. If the fuse cap has an arrow printed on it, push the cap in and turn it counterclockwise.
