    2. INTRODUCTION CONGRATULATIONS! You have just made perhaps the most exciting and dramatic addition that you could possibly make to your audio system. The new dimension of deep, powerful bass provided by your M&K Sound powered subwoofer will positively thrill and excite you. We encourage you to read this owner’s manual, as there is a great deal of information provided here to help you get the best possible performance from your new subwoofer.

  • Page 6: Subwoofer Hook Up

    4. SUBWOOFER HOOK-UP M&K Sound subwoofers come with line-level phono (sometimes referred to as RCA) connectors. If your receiver or processor has a line-level subwoofer output (sometimes labeled “Sub”, “Sub Out”, “SW” or “LFE”) with phono connectors, use it. This is the preferred connection for your M&K Sound subwoofer. FIGURE 1.

    Now, play some music through your system to make sure that the satellite (main) speakers are working properly. Once you confirm that they are, slowly advance the “BASS VOLUME” control. The subwoofer should begin to play. Set the “BASS VOLUME” control to where the subwoofer sounds in balance with the satellite speakers.

  • Page 8: Use Of The Phase Control

    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.

  • Page 9: Crossover Bypass Setting

    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 between 0 – 180, set it to the 0 degree (default) position.

  • Page 10: Using Multiple Subwoofers

    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 specification sheet for frequency response, in order to choose the best working crossover frequency at subwoofer. Setting the sub woofer crossover control to the same frequency as the lowest given value for a main speaker or satellite speaker, is a good start setting.

    11. TROUBLESHOOTING Your M&K Sound subwoofer amplifier provides high reliability and, in the rare event service is ever required, easy modular replacement of parts. This section of the manual will help you to solve or diagnose most problems that can occur with your subwoofer.

    If you hear a persistent hum or buzz through the subwoofer: 1. Because the subwoofer is able to reproduce the 50/60 Hz hum frequency, it is often blamed for causing hum that originates elsewhere in the system. Always avoid running all speaker wires and Phono interconnects cables near to AC cords and component power supplies.

  • Page 13: Speaker Set Up

    14. SPEAKER SET UP 1. Front Speaker Placement The left, right, and center speakers should be equidistant from the main listening position. Try to set up the speakers so that they are reasonably symmetrical to room surfaces. A tape measure may be very helpful. 2.
  • Page 14 8. Channel Calibration Take the measurement at the listening position to establish the reference level. Set all channels to exactly the same level (usually 75 dB for home theater systems.) Use a Sound Level Meter either analogue or digital. Point it directly at the speaker being measured. Set all channels to the same level, using your receiver or processor’s internal test signal.
