If you have two subwoofers, it is not necessary to use both inputs on each subwoofer. Connect the interconnect cable to one "FROM PREAMP" jack only. Run the Left channel interconnect cable to the Left subwoofer and the Right interconnect cable to the Right subwoofer. See Figures 4 and 6.

WIRING WITH THE M&K HP-80 OR VF-80 HIGH-PASS FILTERS (NON-THX)

The M&K HP-80 and VF-80 High-Pass Filters can improve any system that allows its preamp and power amp stages to be separated, by filtering the bass fed to the main amp and Satellite speakers.

These filters will give your system greater dynamic range, lower distortion, and an increased maximum output. To use these filters with an integrated amp or receiver, the amp or receiver MUST have back panel RCA jacks labelled PREAMP/MAIN OUTPUT and POWER AMP/MAIN INPUT. There may be a switch or jumper connections between them, which you will have to remove. If you have any questions about your components, contact your dealer or M&K.

For non-THX systems, your subwoofer is optimized for use with the HP-80 High-Pass Filter. We strongly recommend that you use this filter with any component system that allows for its use. When you use this subwoofer with an HP-80 and M&K Satellites, the combination forms a 4th order Linkwitz-Riley crossover between satellite and subwoofer. The linear phase of this crossover means uncompromised performance with great flexibility in system setup, without requiring elaborate calibrations or adjustments.

Do not use either of these filters with a THX controller. The THX controller has the appropriate filters in its built-in crossover circuitry. Also, do not use a SUBWOOFER OUTPUT jack on your amp or processor to feed any of these filters.

To connect one of these filters, run one set of shielded RCA - RCA interconnect cables from the
