The Array Series: Loudspeaker Systems That Reaffirm JBL’s Commitment To Total Engineering.

The Array Series Solution:

A Compact, Flexible

System For Professionals

Array Series is an optimized system which combines precision engineered transducers and advanced control technology for a level of performance second to none. Since its introduction these system products have found favor around the world in a wide variety of applications: musical theater, concert audio, corporate A/V rental work, dance music club installations and broadcast/film special event support, to name but a few.

The Sum Of Its Parts

Low Frequency Transducers

For Array Series, JBL engineers developed the first-ever neodymium-based pro audio low frequency transducer. This 335 mm (14 in.) device features an advanced magnet structure, used for high flux density and low overall weight. Harmonic distortion is reduced through the use of dual shorting rings

(one aluminum and the other copper). Linearity is maintained, even at high- excursion extremes, with the use of a 100 mm

(4 in.) diameter edgewound

60% compared to competitive products, allowing Array Series systems to deliver higher sound pressure levels at full dynamic range.

A glass fiber/paper composite cone is used to achieve a greater stiffness-to-weight ratio. The new cone formulation, along with its ribbed- wall geometry, greatly reduces distortion by minimizing cone break-up.

High Frequency Compression Driver

Array Series products use a 38 mm (1 1/2 in.) exit compression driver that features a neodymium magnet assembly for maximum magnetic energy and minimal weight. A damped 100 mm (4 in.) diameter pure titanium diaphragm is positioned over JBL’s Coherent

Feature DuraFlex™

Long term enclosure durability is assured by 13-ply birch hardwood construction, proven joinery techniques and JBL’s rugged DuraFlex™ exterior coating. Structural integrity is enhanced by internal steel braces which double as attach- ment points for S.A.F.E.™ flying hardware accessories. The enclosure’s sidewalls taper at 22.5° angles, matching horn coverage angles for effective array construction.

For easy transport, two comfortable handles are installed on the side walls. The 4892A features a 35 mm (1 3/8 in.) pole mount cup on the bottom surface, for use with Tripod

13-ply, 19 mm (3/4 in) void-free, cross-grain hardwood construction for maximum durability in fixed or portable applications.

100 mm (4 in) pure titanium diaphragm features JBL’s patented diamond sur- round to reduce membrane stresses in the support structure. Aquaplas damping reduces break-up modes and smoothes overall response.

VGC™ (Vented Gap Cooling) uses normal cone excursion to force air across the voice coil for maximum heat dissipation, resulting in higher power handling and reduced power compression.

Dual shorting rings, aluminum and copper, greatly reduce 2nd and 3rd order harmonic distortion.

Neodymium magnet structure for light weight and high flux density. Black motor structure is pressed into diecast aluminum frame which acts as heatsink for effective convection cooling.

Large diameter vents prevent compression for linear output during high SPL usage.

Integral steel braces accept S.A.F.E.™ (Secure Array Flying Hardware) for quick, safe rigging.

Optimized System Engineering

To optimize transducer integration, JBL engineers turned to advanced signal processing technology to assure smooth response and phase integrity. Crossover filters, transducer alignment, system equalization and protective limiting are implemented to be completely transparent, allowing the transducers to perform to their maximum potential. Available digital controllers offer the user a choice of features and performance to complement any installation or portable touring system.

aluminum ribbon voice coil. The audible result is absolute clarity and definition in the bass/low mid frequency region.

JBL’s exclusive VGC™ (Vented Gap Cooling) technology is part of an optimized Thermal Management System which makes efficient use of both forced air and convective cooling. Convection cooling is maximized by encasing the compact, powerful neodymium magnet within the diecast aluminum frame, engineered to act as a large, efficient heatsink. This design reduces thermal compression by as much as

Wave™ phasing plug for phase-correct summing at the exit throat.

Optimized Aperture™ Bi-RadiaI©Horns

To achieve smooth, even dispersion at low distortion in both the horizontal and vertical planes, Optimized Aperture Flat-Front Bi-Radial horns were developed for Array Series systems. The family includes a 45° model with a uniform, narrow coverage pattern segment that combines well in arrays. 60° and 90° horns provide accurate, consistent coverage

Speaker Stands. The grille is 16 gauge perforated steel, lined with open-cell reticulate foam to pro- tect against moisture damage and dust. Input is through two paralleled 8-pole Speakon™ connectors, which access each transducer component individually.

Advanced Control Electronics

Sophisticated control electronics allow

Array Series transducers to perform to their maximum capability. Careful consideration has been given to the overall circuit topology of crossover filters, transducer alignment,

and user convenience available only in the digital domain. Either choice will provide superior, high level sound quality.
