General Product Description
The CFID32-8 and CFID32T are 32-watt wide angle paging
projectors designed for high speech clarity under difficult noise
conditions.
The drivers employ rugged phenolic diaphragms, 1.5-inch diameter
voice coils and “rim centered” ferrite magnet structures for long life
and reliability.
The transformer model CFID32T includes connections for 25 V and
70 V distributed systems and a screwdriver operated power tap
select switch.
A nominal 55° horizontal by 75° vertical coverage pattern, together
with a low-frequency cutoff of 300 Hz, provides excellent articulation
in demanding applications.
The CFID32-8 (CFID32T) is molded from non-resonant and
weatherproof Cycolac. Exclusive Uni-Lok swivel mount allows
precision mounting in a variety of installations. The gland nut
connection insures a weather-tight seal.
Ideal for both indoor and outdoor applications, these drivers are
well suited for any installation requiring rugged, reliable performance.
Architects’ and Engineers’ Specifications
The loudspeaker shall have a rectangular reflex horn with an
exponential expansion rate. The driver employs a rugged phenolic
diaphragm and high-temperature rated 3.81 cm (1.5 in.) voice coil.
The axial frequency response will extend from 330 to 4,200 Hz and
the horn shall exhibit a low-frequency cutoff of 300 Hz. Sound
pressure level will be 107 dB (1 W/1 M) with a 500 to 5,000 Hz pink
noise signal applied, and the horn will produce a horizontal
beamwidth of 55° and a vertical beamwidth of 74° at 2 kHz.
The loudspeaker shall be capable of handling a 32-watt, 500 to
5,000 Hz pink noise signal with a 6 dB crest factor for a period of
eight hours.
