JBL Professional is expanding its LSR4300 family by introducing the LSR4312SP Linear Spatial Reference powered subwoofer for multichannel music, post and broadcast production. The LSR4312SP features JBL's Room Mode Correction (RMC) technology for measuring and automatically compensating for low-frequency problems. It also employs the Harman HiQnet protocol to network with LSR4300 Series studio monitors and computer-based recording systems. The LSR4312SP will be offered in single and complete 5.1 surround-sound packages with the LSR4326P and LSR4328P studio monitors.

The JBL LSR4312SP is based on a 12-inch low-frequency transducer with a neodymium motor structure and powered by a 450-watt amplifier. The LSR4312SP's input complement has a dedicated LFE low frequency effects input and five balanced XLR bass management inputs with selectable cross-over for 5.1 surround sound production. Additionally, stereo 24-bit, 96kHz digital S/PDIF and AES/EBU inputs can be assigned as LFE or stereo bass management inputs.

Calibration of the system is accomplished by connecting the LSR4300 calibration microphone to a networked LSR4328P or LSR4326P and pressing a button.

Using LSR4300 Control Center software, subwoofer bass management and LFE settings and all system settings can be controlled from Windows- and Macintosh-based recording systems. Complete system configurations can be saved in the computer and recalled.

Powerful Subwoofer with Room Mode Correction
JBL caused quite a stir with their introduction of the LSR4326P and LSR4328P monitors, and now they have completed the set with the introduction of the LSR4312SP subwoofer. A system configured with the LSR4312SP subwoofer provides professional bass management of the main channels, plus LFE (low frequency effects) input, adjustable crossover points, and powerful features for surround sound production.

JBL LSR4312SP Powered Subwoofer at a Glance:

  • 12" low-frequency driver with 450-watt power amplifier
  • The perfect sub for LSR4300 Series monitors
  • Room Mode Correction compensates for problem standing waves
  • Part of an intelligent monitoring system
12" low-frequency driver with 450-watt power amplifier
Based on a custom 12" low frequency transducer with a Neodymium motor structure, the LSR4312SP is powered by 450 watts of amplification providing exceptional dynamic range and low frequency response into the 20Hz range. The new sub has balanced analog and digital inputs to enable multi-channel production with comprehensive bass management capabilities.

The perfect sub for LSR4300 Series monitors
The JBL LSR4312SP sub is the perfect foundation for a 2.1 or 5.1 surround monitoring system when teamed with LSR4326P or LSR4328P monitors. The LSR4312SP can be networked with the LSR4328P or LSR4326P to create integrated surround sound systems without the need an external monitor controller.

Room Mode Correction compensates for problem standing waves
Great mixes start with accurate monitors. The LSR4312SP incorporates JBL's next generation RMC Room Mode Correction system incorporates a powerful analyzer into each speaker that automatically analyzes and compensates for problems caused by low-frequency standing waves and proximity to boundaries. Truly putting technology to work, all of this is accomplished by simply plugging the LSR4300 calibration microphone into the speaker and pushing a button. A JBL first, the LSR4300 meter provides a reference of the output from each speaker in the system. The results are a revolution in professional mixing: a calibrated listening environment where the monitors truly work in harmony with the room. This creates a stunningly clear and articulate sound stage enabling reliable mixes that translate faithfully to the outside world.

Part of an intelligent monitoring system
Control of system level, individual speaker solo, input source selection, high- and low-frequency EQ settings, and adjustment of all parameters can be made from each speaker's front panel, with the system's infrared remote control, or with LSR4300 Control Center Software. For unprecedented performance and convenience the LSR4300 Series incorporates the new Harman HiQnet protocol that enables a coordinated calibration of all speakers, intelligent configuration of surround sound systems, and synchronized control of all speakers in the system.

LONDON, ENGLAND, September 10, 2006 - At this year's PLASA exhibition, JBL Professional officially brings its revolutionary LSR4300 studio monitor series to 5.1 surround sound environments and beyond with the delivery of the LSR4312SP subwoofer. The LSR4300 Series has enjoyed tremendous success in the recording and broadcast markets due to the product's exceptional sonic performance and the integration of JBL's groundbreaking Room Mode Correction (RMC) technology.

"Since its introduction last year, the LSR4300 series has achieved widespread adoption throughout the industry by professional project recording/post production and broadcast facilities" said Peter Chaikin, Director of Marketing, Recording & Broadcast, JBL Professional. "With the delivery of the LSR4312SP Subwoofer, production of professional 5.1 surround program is within reach of any studio. Customers can affordably configure large networked multi-channel systems and extend the frequency response of existing LSR4300 systems into the 20Hz region."

The JBL LSR4312SP subwoofer is based on a 12-inch low-frequency transducer with a neodymium motor structure and powered by a 450-Watt amplifier for exceptional low-frequency accuracy and dynamic range. When integrated with LSR4326P and LSR4328P studio monitors, the LSR4312SP extends the low frequency of the system, allowing flat reproduction into the 20 Hz range. The LSR4312SP's comprehensive input complement has a dedicated LFE Low Frequency Effects input and five balanced XLR bass management inputs with selectable cross-over for 5.1 surround sound production. Additionally, two-channel 24-bit, 96 kHz digital S/PDIF and AES/EBU inputs can be assigned as LFE or stereo bass management inputs.

With surround sound production on the rise, the LSR4300 system is engineered to be 'surround smart." The Harman HiQnet network along with LSR4300 Control Center Software simplifies setup and control of large surround systems with up to eight LSR4326P or LSR4328P monitors and two LSR4312SP Subs in a single system. Control Center Software has a virtual "monitor section" with a system volume control, individual channel solo and mute, monitor source selection, eliminating the need to purchase an outboard speaker controller. Additionally, the entire system may controlled from anywhere in the room using the LSR4300 wireless remote control. Recognizing the smaller facility may not have the space to position surround and center channels at the optimum distance, the LSR4300 adjusts the output of each speaker on the network to accurately balance sound arriving at the mix position. Additionally LSR4300 Control Center Software displays the precise distance of each speaker from the listening position.

Acknowledging that many home studios and smaller recording facilities are less than perfect from an acoustic standpoint., JBL Professional introduced the LSR4300 Series with stunning accuracy and features to overcome room-related problems that have plagued mixers and project studios. JBL's next-generation automated RMC Room Mode Correction technology, incorporates a built-in analyzer in each speaker that measures and automatically compensates for low-frequency problems caused by standing waves and boundaries. Tuning of the system is simply accomplished by connecting a supplied calibration microphone to the speaker and pressing a button. The RMC system can be calibrated and settings can be viewed on a Mac or PC computer desktop using LSR4300 Control Center Software. By adding an LSR4312SP Subwoofer to an existing system, more complex room problems can be tackled and the power of the RMC system is effectively doubled.
