General Care

CROSSOVER FREQUENCY Use the crossover frequency knob to adjust the upper end of the subwoofer's frequency response. The crossover control determines the highest frequency your subwoofer will reproduce. It allows a seamless transition from subwoofer to satellite speakers. When using small satellite speakers (without much low end), you want the crossover frequency more toward the upper end

(150 Hz) to fill in the sound your satellites can't reproduce. When using larger main speakers, a setting more towards the 90 Hz end gives a smoother transition from your PSW subwoofer to your main speakers. Experiment until you find a setting that meets your satisfaction.

Your PSW subwoofer turns itself off internally. For extended periods of non-use (i.e., vacations, etc.) you may wish to unplug the PSW subwoofer.

PLACEMENT – CAUTION: Do not place your PSW subwoofer next to heaters, furnaces, or any other heat sources. Be sure not to pinch or compress the power cord.

Since the low frequencies produced by your PSW subwoofer are non-directional, the placement of your subwoofer is not critical. You may place it under an end table, next to the wall, next to T.V., anywhere you would like. However, the closer the subwoofer is to walls, the more bass will be realized. Corner placement will result in maximum bass output.

Use the POLARITY switch to maintain proper acoustic summation with the main speakers. Listen to your PSW subwoofer and main speakers with the switch on "0˚", then listen to the same material with the switch on "180˚". Decide which way sounds better and leave the switch in this position. You should repeat this procedure if you move your PSW subwoofer to another part of the room.

ALC PROTECTION CIRCUITRY Your PSW series amplifier has a built-in Automatic Level Control circuitry that comes on automatically when subjected to high input signal levels. It helps to protect the subwoofer driver from being damaged by accidental mis- use, assuring you of many years of excellent performance.

Use a damp cloth for cleaning your PSW subwoofer cabinet. Do not use detergents or other cleaners.

TROUBLESHOOTING / SERVICE Your PSW subwoofers should only be serviced by an authorized JBL repair station. Woofers are replaceable by repair station only. Do not remove the amplifier from the cabinet. There are no user- serviceable parts inside.

Before seeking service for your PSW subwoofer, please recheck all connections as outlined in this manual. Verify that your AC wall power source is working properly by checking with another appliance.
