Delivering greater accuracy and dynamic range to post-production control rooms, HARMAN’s JBL Professional is showcasing the M2 Master Reference Monitor at NAB 2013 at the Las Vegas Convention Center. The largest speaker in JBL’s studio monitor line, the M2 integrates new JBL transducer technologies and patented innovations in a compact, 2-way system.
The M2 can be placed in any production environment free-standing, behind the screen or soffit mounted to provide a superior level of accuracy and performance. The compact footprint of the M2 allows placement in rooms too small for traditional cinema screen channel loudspeakers. At 49.5x20x14 inches (HxWxD), the M2 Master Reference Monitor allows flexibility of placement in small and medium size dubbing stages, screening rooms, and reference environments, free-standing and behind the screen.
The M2 Master Reference Monitor design leverages JBL’s new D2 Compression Driver which uses two annular diaphragms and two voice coils to deliver extended high frequency response and very low distortion at very high sound pressure levels. The D2 is mated with JBL’s new 2216ND Differential Drive 15-inch woofer also with dual voice coils, incorporating a patented wire application that reduces power compression enabling linear output regardless of playback level. With these two drivers as the engine, JBL reports that the M2 Master Reference Monitor delivers extended in-room response of 20 to 40k Hz for high-resolution recording formats, and 129dB SPL at one meter, providing the necessary dynamic range for music and film production.
For the M2, JBL engineers pioneered a new patent-pending waveguide dubbed “Image Control,” which the company says enables neutral frequency response—not just on-axis, but off-axis in the vertical and horizontal planes all the way down to the M2’s 800Hz crossover point. The unique geometry of the waveguide allows the M2 to deliver high-frequency detail and imaging and natural timbre at any listening position, in a broad range of acoustic environments.
Harman’s Crown I-Tech power amplifiers complete the system, providing greater than a kilowatt of clean power to the 2216ND woofer and the D2 high-frequency driver. In conjunction with the M2’s revolutionary waveguide, digital signal processing in the Crown I-Tech or BSS Soundweb London processor allows the implementation of an ideal crossover, while providing the option for storage of EQ presets. In conjunction with measurement software, Harman HiQnet System Architect software allows networked control of system calibration and tuning to address non-linearity in the room, ensuring a high degree of accuracy particularly in the room-dependent low-frequency area, whether the M2 is free-standing, soffit-mounted or placed adjacent to a wall.
