TECHNICAL SPECIFICATIONS CH491
DESCRIPTION
A 2-way mid/high system (passive crossover) housed in a
trapezoidal enclosure. Includes a horn-loaded 10-in midrange
cone and a 1-in exit compression driver on a 90 x 45 con-
stant directivity horn.
APPLICATIONS
The CH491 compact Virtual Array mid/high module works
with BH or BV Series LF systems to create true 3-way arrays
in permanent installations. 3-way design dramatically im-
proves the quality of vocal reproduction while the cone-driven
midrange horn extends pattern control into the lower oc-
taves. Also effective as a stand-alone, voice-only system.
Comprehensive 3/8"-16 mounting/suspension points. Six year
warranty.
Applications include:
Stadiums
Arenas
Convention Centers
Large HOW’s
Small HOW’s
Major Malls
