OPERATION
Power
When the unit is plugged in and the power switch is on and no signal is received, the LED on the top of the unit will turn red. When a signal is present, the LED will turn green. Note: It will take several minutes for the LED to turn from green to red after the input signal to the subwoofer is removed. Due to JBL�s unique high-output, high-efficiency amplifier design, power consumption is minimal when the subwoofer is not receiving a signal. Of course, the subwoofer can be turned off, whenever desired, if you do not wish to leave it in auto (standby) mode.
Level Control
The subwoofer Level Control adjusts the volume of the subwoofer relative to the rest of the system. Proper level adjustment depends on several variables such as room size, subwoofer placement, type of main speakers and position. Adjust the subwoofer level so that the volume of the bass information is pleasing to you.
Crossover Adjustments
The Crossover Frequency Control determines the highest frequency at which the subMin

woofer reproduces sounds. If your main speakers can comfortably reproduce some lowfrequency sounds, set this control to a lower frequency setting, between 50Hz and 100Hz. This will concentrate the subwoofer�s efforts on the ultradeep bass sounds required by today�s films and music. If you are using smaller bookshelf speakers that do not extend to the lower bass frequencies, set the low-pass crossover control to a higher setting, between 120Hz and 150Hz. This control is not used when the LFE switch is in the �LFE� position.
