If you are using two Subwoofers, run the left channel interconnect cable to the left Subwoofer and the right channel cable to the right Subwoofer.

USING THE HP-80 OR VF-80 ELECTRONIC HIGH-PASS FILTERS

The M&K HP-80 and VF-80 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 and Satellite speakers.

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.

If you have a multichannel surround sound system, we offer both 2 and 3 channel versions of each filter. Remember that to use these filters, your component must have both a preamp-type output and a power amp input. The 3 channel VF-80 and HP-80 can only be used if your component has a dedicated subwoofer output jack.

If your component has its own high or low-pass filters, they should be turned off when using the VF-80 or HP-80. Do not run your system with multiple filters. If your receiver or controller is THX- certified, you do not need these filters. All THX controllers and receivers have the proper high and low- pass filters built in.

These filters will give you greater dynamic range, lower distortion, and an increased maximum output level. If you have any questions about the suitability of your components, please contact your M&K dealer or the factory.

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. This is the normal sound of its power supply charging and discharging when it is plugged in and unplugged.

Once your system wiring is complete and the Subwoofer is plugged into the wall,leave it plugged in, even when the system is turned off. The normal mode of operation for the Subwoofer is to remain plugged in 24 hours a day. Among other things, this means that you don't have to walk over to the Subwoofer to turn it on every time you want to use the system.

If you decide to plug the Subwoofer into a switched outlet on another component, that outlet must have the following minimum power ratings:

Minimum of 200 watts: V-75 Mk II, VX-7 Mk II

Minimum of 300 watts: MX-105, MX-125 Mk II, MX-70B, V-125

Do not use a switched outlet with the MX-300 and MX-200.

Now, play some music through your system to make sure that the Satellite speakers are working properly. If they are, carefully advance the "BASS LEVEL" control. The Subwoofer should begin to
