Harman’s JBL Professional 7 Series Monitors

Monitoring System for Post-Production, Broadcast Control Rooms

At NAB 2016 in Las Vegas, Harman JBL’s Peter Chaikin was giving demos of the company’s new 7 Series Master Reference Monitors featuring easy integration and stellar sound and control across a network. Developed to meet the requirements of broadcast and post-production facilities that produce content in immersive audio formats, the LSR708i and 705i Master Reference Monitors are described as the heart of a complete, modular system that can be scaled to any size production room and any number of channels.

The 708i 8-inch two-way, and 705i 5-inch 2-way installed monitors promise remarkable frequency response and output despite their compact sizes. To deliver exceptional performance, JBL developed a new miniature high-frequency transducer—the 2409H—featuring JBL’s low-mass, annular diaphragm design that allows very high output with low distortion and high frequency response to 36kHz. JBL also engineered two new high-excursion 5-inch and 8-inch woofers, the 725G and 728G that give the 708i and 705i robust low-frequency output into the 30Hz range and peak system output of 113dB and 107dB respectively. JBL’s patent-pending Image Control Waveguide and a sophisticated dividing network together produce what JBL says is an imperceptible crossover transition, detailed, spatial imaging and neutral response, particularly in the critical dialog range. Front-ported birch plywood install-ready enclosures include bottom and rear-panel mounting points. With a range of available mounting brackets, the speakers’ placement can be optimized to maintain sight lines to video displays.

To reduce enclosure size and installation cost, the speakers are centrally powered by Harman’s Crown DCi 8|300N eight and four-channel power amplifiers. The 705i and 708i can be driven by a single amp channel or bi-amplified, and tuned for room-to-room consistency Added to the 7 Series system, Harman’s BSS Soundweb London signal processor can be networked with the amplifiers to provide down-mix, sophisticated bass management capabilities and a range of I/O options including AES, Dante, and AVB. The entire system can be externally controlled using Harman HiQnet Audio Architect software, a hardware controller or wireless tablet.
