The PA430 and PA430T are 30-watt constant-directivity paging projectors for use in any public address or paging application.The drivers employ rugged phenolic diaphragms, 1.5 inch diameter voice coils and "rim centered" ferrite magnet structures for long life and reliability under extreme operating conditions.A 12 inch connecting cable, color coded for phase, is provided for connecting to the PA 430 and PA430T.The transformer model (PA430T) includes connections for 25V, 70.7V, and 100V distributed systems and a screwdriver-operated power tap select switch. (Patent #4, 775, 766)A nominal 60° horizontal by 40° vertical coverage pattern together with a low-frequency cutoff of 350 Hz provides excellent articulation in demanding applications.The PA430 (PA430T) is molded from high-impact ultraviolet-inhibiting acrylic-styrene-acrylonitrile (ASA). A positive lock, super tough nylon swivel base and rear housing provides maximum mounting flexibility and ease of installation. (Patent #4,984,278)Ideal for both indoor and outdoor applications, these drivers are well suited for any installation requiring rugged, reliable performance.
