HARMAN KARDON PS60
Owner's Manual

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 (200 Hz) to fill in the sound your satellites can't reproduce. When using larger main speakers, a setting more towards the 50 Hz end gives a smoother transition from your PS subwoofer to your main speakers. Experiment until you find a setting that meets your satisfaction. MULTICOLOR LED INDICATOR OPERATION The LED on the front of the enclosure signifies the following operation states of the PS subwoofer: RED - When your PS subwoofer isn't receiving a music or source signal and the power switch is turned on, the LED indicator turns REDtelling you that the unit is plugged in and ready for operation. At this time, the amplifier is in a "stand-by" mode, effectively turned off and waiting for a signal from the source amplifier. GREEN - When your PS subwoofer picks up a source signal, it turns on instantly and

begins to play. The LED turns green. After approximately 3 minutes of non-use (no signal being received), your PS subwoofer goes into the auto shutoff mode. The LED turns RED to signify this stand-by condition. AMBER - The LED turns amber briefly when the amplifier is in the protection mode. This occurs when the subwoofer power switch is turned on while your receiver/T.V. /source amplifier is sending a signal to the PS subwoofer. NOTE: When the amplifier is in the stand-by mode it is effectively turned off. The Red LED tells you that the PS subwoofer is plugged into the AC wall power with its power switch turned on, but the amplifier circuitry is not engaged. You do not have to reach to the back panel and turn the power switch off after every use. Your PS subwoofer turns itself off internally. For extended periods of non-use (ie, vacations, etc.) you may wish to turn the PS subwoofer off using the power switch. PLACEMENT - CAUTION: Do not place your PS 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 PS 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.
