JBL Array Series 4894-90 - Manual (Page 2)

4894-90 High Power Two-way Loudspeaker System
the accurate reproduction at high power levels with
minimal power compression. A new 38 mm (1% in)
exit neodymium high frequency compression driver
with Coherent Wave’” phasing plug and 100 mm (4 in)
titanium diaphragm delivers low distortion response to
beyond 20 kHz. A 90° Optimized Aperture™ Flat-Front
Bi-Radial ® horn² provides accurate pattern control over
its entire bandwidth.
S.A.F.E.™ Secure Array Flying Ergonomics
Important for both portable and fixed installation appli-
cations is the ability to rig a cluster quickly, but with
absolute safety. The 4894-90 has four internal steel braces
that are ready to accept optional bolt-on truss modules.
An array to provide desired coverage can be quickly
assembled using a few basic fittings. Ultimate break
strength of this method exceeds 2700 kg (6000 lb). A com-
plete line of hardware is available for many applications
including flying subwoofers in an array.
Active Control
The ASC24 provides cost effective analog signal process-
ing with simple setup. The DSC280 offers additional
precision, flexibility, and user convenience available
only in the digital domain. Both provide superior high
level sound quality.
Enclosure
Extremely rigid 19 mm ( ¾ in) 13 ply hardwood, a
textured black paint finish, and a perforated 16 ga.
steel grille form a durable package.
Applications
The 4894-90 is ideal for applications requiring high
fidelity, high level music reproduction, or high intelligi-
bility speech reinforcement. For applications requiring
very low frequency reinforcement the 4893 subwoofer’s
dimensions match the 4894-90 allowing convenient
integration.
