LSR310S POWERED STUDIO SUBWOOFER FEATURES

Producing extended low frequency response into the 20Hz region, the LSR310S is the perfect match for the 3

Series MkII studio monitors. The LSR310S feature set includes:

• A Magnetically-shielded low frequency transducer, equipped with a 1.5" voice coil and robust motor

structure for excellent low frequency performance. By reducing thermal-related effects, the 3 Series MkII

Studio Monitors and LSR310S Subwoofer sound the same at low, medium, and high levels. The woofer

is magnetically shielded to prevent interference with magnetically sensitive displays and equipment. The

woofer’s self-repairing dust dome is resistant to dents caused by ngers or external objects.

• A custom-designed down-ring, high-excursion 10" woofer with additional bucking magnet.

• A 200 watt Class-D power amplier with abundant output and dynamic headroom for the most demanding

production styles.

• The patented Slip Stream low frequency port, designed to work in concert with the 3 Series MkII woofers

for accurate bass response at all playback levels.

• A detented VOLUME control, making it easy to balance the LSR310S with the studio monitor system.

• Balanced XLR and ¼" input connectors.

• Two XLR output connectors to add the LSR310S to any studio monitor system and extend its low

frequency response.

• A +4dBu / -10dBV INPUT SENSITIVITY switch for connection to consumer or high-output professional

equipment without danger of input overload.

• Three CROSSOVER settings:

• 80Hz – This setting implements high- and low-pass lters to create a seamless blend of the

LSR310S with the 3 Series MkII studio monitors or other speaker system.

• XLF – This special setting activates a 120Hz high-pass lter in conjunction with a low frequency

tuning that approximates the tuning used in club playback systems. Using this setting, the bass

output more than doubles.

• External – The external setting bypasses all ltering, allowing use of an external active crossover.

• A protective limiting circuit allows the subwoofer to operate continuously at full output without failure.

JBL PROFESSIONAL RELIABILITY

Prior to becoming a production-ready design, each 3 Series model is subjected to JBL’s tough 100-hour

power test, in which the speaker is required to play continually at full output for 100 hours without failure. This

demanding test ensures the 3 Series speakers will deliver years of reliable performance. To get the most out

of the JBL 3 Series, please review this owner’s manual and keep it on hand for future reference. Also, please
