Northridge, CA (April 10, 2006)–Expanding the JBL LSR4300 family, JBL Professional has introduced the LSR4312SP Linear Spatial Reference Powered Subwoofer for multichannel music, post and broadcast production. The LSR4312SP features JBL RMC (Room Mode Correction) and employs Harman HiQnet protocol to network with LSR4300 Series Studio Monitors and computer-based recording systems.
JBL’s LSR4312SP The LSR4312SP will be offered in single and complete 5.1 surround-sound packages with the LSR4326P and LSR4328P Studio Monitors.
“The bulk of today’s production is carried out in acoustically less-than-perfect rooms using computer-based systems,” said Peter Chaikin, director of recording and broadcast, JBL Professional. “The LSR4312SP tackles low frequency problems in the room and can be adjusted and controlled by computer without leaving the mix position.”
The JBL LSR4312SP is based on a 12-inch low-frequency transducer with a neodymium motor structure and powered by a 450-Watt amplifier. When integrated with LSR4326P and LSR4328P studio monitors, the LSR4312SP Subwoofer extends the low frequency of the system, allowing flat reproduction into the 20 Hz range. The LSR4312SP’s comprehensive input complement includes 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, 96 kHz digital S/PDIF and AES/EBU inputs can be assigned as LFE or stereo bass management inputs.
Low-frequency standing waves and proximity of the speakers to boundaries such as walls, corners and the work surface can give a misleading impression of bass at the mix position. With the understanding that much of modern recording is done in less-than-ideal acoustic environments, the LSR4312SP incorporates a powerful analyzer into the speaker along with JBL’s RMC, which measures and automatically compensates for these low-frequency problems. Calibration of the system is accomplished by connecting the LSR4300 calibration microphone to a networked LSR4328P or LSR4326P, and pressing a button.
Additionally, the LSR4312SP is a “Surround Smart” subwoofer, incorporating Harman’s HiQnet protocol to allow networking with LSR4328P and LSR4326P. Configuration and control of large surround systems is accomplished by connecting all speakers using supplied CAT5 network cable. When networked, the LSR4312SP and the entire system can be controlled from any speaker, wireless remote control or LSR4300 Control Center Software.
Features such as System Volume, Input Source Selection, Mute and Solo can be controlled without leaving the mix position, eliminating the requirement for outboard multichannel speaker controllers. Using LSR4300 Control Center Software, subwoofer bass management and LFE settings and all system settings can be controlled from Windows and Macintosh computer recording systems. Complete system configurations can be saved to the computer and recalled.
The LSR4312SP will ship this spring with an MSRP of $1,100.
