receiver, amp or preamp's MAIN OUTPUT to the input jacks on the HP/VF-80. Run another set of interconnects from the high frequency output jacks on the filter to receiver or amp's POWER AMP inputs. Last, run interconnects from the subwoofer output jacks to the subwoofer's "FROM PREAMP" jacks. See the instructions enclosed with your filter for wiring diagrams.

To use these filters, make certain that the "BASS LEVEL" switch is set to "VARIABLE" and that the "LOW PASS FILTER" switch is set to "24 dB/OCTAVE"

TESTING THE SUBWOOFER (NON-THX)

Once all of the interconnect cables are in place, you are ready to plug in your subwoofer. Make sure the "LOW PASS FILTER" switch is set to the "24 dB/OCTAVE" position and the "BASS LEVEL" control to set to "VARIABLE". Make sure the "SUBWOOFER PHASE" switch is set to the "+" position. Then plug the AC cord in. You should see the red LED on the back panel of the subwoofer illuminate.

When 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.

DO NOT PLUG THE SUBWOOFER INTO A SWITCHED OUTLET ON ANOTHER COMPONENT. THE SUBWOOFER CAN DRAW UP TO 400 WATTS FROM THE

AC LINE. IT MUST BE PLUGGED INTO A SOLID AC LINE.

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 play. Set the "BASS LEVEL" control where the subwoofer sounds in balance with the Satellite speakers. If the system is not working properly, unplug the subwoofer and check all of your connections. Call your dealer or the factory if you cannot solve any problem.

SETTING THE SUBWOOFER LEVEL (NON-THX)

Here are two ways to set the subwoofer level. First, if you can obtain a spectrum analyzer, you can accurately match the subwoofer to the main speakers. First feed a wideband pink noise signal into the full system (both the satellites and the subwoofer). Then set up the analyzer at the main listening position. Adjust the "BASS LEVEL" control until the analyzer display shows the flattest response through the 70 - 125 Hz midbass region.

If you don't have access to an analyzer, the best way to match the level of the subwoofer to your system is to do it by ear, listening over several hours to familiar recordings. Make adjustments to the level in small increments, depending on whether the bass level sounds too high or too low.

There is a possibility that your surround sound processor has a built in test generator for the subwoofer level, but the virtually all non-THX processors do not. If you do have such a surround sound processor, see SETTING SUBWOOFER LEVEL (THX), on page 8.

In any case, remember that you can always deliberately set the level higher if you want more bass or lower if you don't want to disturb your neighbors.

USING TWO SUBWOOFERS (NON-THX)

Using two subwoofers in your audio/video system will give you the ultimate in bass performance. It will give you improved impact and definition, as well as greater output and dynamic range. If you locate the subwoofers in different parts of the room, you will hear a better overall frequency
