Electro-Voice CFID32-8 Manuals

CFID32-8 CFID32T Variable Power Paging/ Talk-Back Speaker 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.
