Generally speaking good copy; a few pages too hard contrast...
Good service and communication.

I purchased the unit from a private party and the original owners manual was not available. Having the ability to download it was extremely helpful and clarified operating the equipment immensely. This is a complicated unit and without the manual I would not have been able to maximize it's potential. Thank you.

Being a user of older radios of many kinds, preferring them over more modern rigs, this manual was invaluable in the programming of my two. I now know for certain what the assorted buttons functions are, and am very grateful to have found this excellent site. Many thanks for your assistance, Tony.
Operation
Power
When the unit is plugged in and no signal is received for approximately 10 � 15 minutes, the subwoofer will go into a standby mode until a signal is present. Due to JBL�s unique, high-efficiency digital-amplifier design, power consumption is minimal when the subwoofer is not receiving a signal.
Level Control
The subwoofer Level Control, located on the rear panel, 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 listener position. Adjust the subwoofer level so that the volume of the bass information is pleasing to you.
Crossover Adjustments
Low-Pass Control The Low-Pass control determines the highest frequency at which the subwoofer reproduces sounds. If your main speakers can comfortably reproduce some low-frequency sounds, set this control to a lower frequency setting, between 50Hz � 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 � 180Hz.

speakers that do not extend to the lower bass frequencies, set the high-pass crossover control to a higher setting, between 125Hz � 180Hz. With this setting, your main speakers will not have the burden of reproducing any low-frequency sounds. � If you hooked up your subwoofer as shown in Hookup 1 on page 3, the high-pass frequency is fixed at 180Hz. � If you hooked up your subwoofer as shown in Hookup 2 on page 4, there is no high-pass control. Unless your receiver/amplifier incorporates a high-pass crossover, your main speakers will continue to get a full-range signal.
Final adjustment and blending of the low-pass and high-pass controls may evolve over several listening sessions. A good starting point would be to set both the low- and high-pass controls to the same frequency and adjust from that point.
