JBL Professional Launches Networked 5.1 Surround Systems

At NAB 2007, JBL Professional brings its LSR4300 Series studio monitors to broadcast applications with the introduction of two 5.1 surround sound systems featuring networking functionality and JBL’s RMC Room Mode Correction technology.

The LSR4328P/5.1 system includes five LSR4328P powered speakers and one LSR4312SP subwoofer. The LSR4326P/5.1 system includes five LSR4326P powered speakers and one LSR4312SP subwoofer. The systems come complete with an accessory kit including a calibration microphone, wireless remote control, Control Center software for Macintosh and Windows computers, USB and Cat-5 cables.

The Harman HiQnet network, along with LSR4300 Control Center software, works with up to eight LSR4326P or LSR4328P monitors (with 6- and 8-inch woofers respectively) and two LSR4312SP subwoofers in a single system. The software includes a virtual “monitor section” with a system volume control, individual channel solo and mute, and monitor source selection. Additionally, the entire system may be controlled from anywhere in the room using the LSR4300 wireless remote control, which adjusts the output of each speaker on the network to accurately balance sound arriving at the mix position.

When connected to the network, the auto-calibration feature in the new LSR4312SP powered subwoofer automatically balances the sub to the rest of the system. Using the supplied remote control or Control Center software, all settings of the sub can be auditioned and adjusted without leaving the mix position.

For digital production, each speaker includes 24-bit/96kHz AES/EBU and S/PDIF digital inputs to interface with digital broadcast consoles, computer audio I/O, playback sources and processors. Onboard input switching allows the user to monitor a range of analog and digital playback sources via supplied remote control, software or the speaker’s front panel input control.

The inclusion of a tri-color meter display on the speaker’s front panel allows broadcasters to monitor system levels. A complement of illuminated controls provides access to EQ, SOLO, Input selection volume and RMC calibration. When networked, the front panel of any speaker controls all speakers in the system.
