The new dimension of deep and powerful bass provided by your M&K Subwoofer will thrill and excite you. We encourage you to read this owner's manual, as there is a great deal of information prov

You will see two RCA input jacks labelled "FROM PREAMP," and two sets of speaker wire input terminals labelled "FROM AMPLIFIER" and "TO SPEAKERS." You must choose to use either the speaker wire inputs or the RCA jack inputs. STANDARD AMPLIFIER/SPEAKER WIRE CONNECTIONS The most common way to hook up the S

SATELLITE SPEAKER WIRING OPTION 1 With this option, you connect the wiring for the Satellites directly to the Subwoofer. There is no performance advantage with this method, but it may require less speaker wire and be more convenient. 1. Run speaker wire between the Subwoofer's Left cha

But if you get weak or no output when you connect your speaker this way, connect both sets of speaker

To roll off (filter) the signal fed to the Satellite speakers to achieve true biamplification, you must: 1. Have a separate amp and preamp OR a receiver or integrated amp that allows you to separate its amp and preamp stages. 2. Add an M&K Electronic High-P

WIRING WITH THE LP-1S & VF-100 ELECTRONIC HIGH-PASS FILTERS The M&K LP-1S and VF-100 Electronic High-Pass Filters can improve the performance of any system that allows for separation of its preamp and power amp stages by filtering the bass signal fed to the main amplifier

Set the "BASS LEVEL" control to "MIN". Then plug the AC cord in. You should hear a thump from the Subwoofer. This is the normal sound of its power supply charging and discharging when it is plugged in and unplu

If you hear more bass, the new connections are correct. If you have two Subwoofers, perform one test for each Subwoofer. When you perform each test, make sure the other Subwoofer is not op

FINE-TUNING SUBWOOFER PLACEMENT If you have the physical space in your room and the interest to experiment with the placement of your Subwoofer, you may be able to optimize its location and sound. If you want to do this, listen to the Subwoofer after it is hooked up, using a familiar CD, LP, or tape wit

This may occur when video sources (especially older films and some television) have very little deep bass present. You may also want to exaggerate the effect to make spectacular video sources even more impressive! When your subwoofer is going t
