AT-APX40TN • A 40 watt constant-directivity paging loudspeaker for use in public address or paging applications. • 40W. 107dB. 2.5, 10, 20, 30, & 40 Watts.
REFLEX HORNS
AT-BIA100 • The original reflex horn featuring a bi-axial design with twin air columns and exponential bell for wide-angle coverage with a linear frequency response. The easily-mounted horn features the labor-saving patented gimbal-mount brack- et assembly (U.S. Patent # 4,325,529) which allows for directional positioning up to 180° vertically and horizontally. Provides 130° x 60° wide-angle sound coverage. Works with all Atlas Sound PD Series compression drivers.
AT-CJ46 • Wide-angle sound projector screw mounts to Atlas Sound PD and SD Series compression drivers to provide maximum audio penetration through adverse ambient sound levels and coverage over long distances. Features a heavy-duty steel mounting bracket with positive lock for horizontal and vertical positioning in single or stacked multi-unit clusters. Provides 120° x 60° sound coverage.
AT-DR72 • Double re-entrant horn is designed for use with compression driver units to offer superior music and voice communications over distance and ambient noise. This circular projector is equipped with a resonance damping ring for best response through an extended frequency range. This weather-resistant unit will accommodate Atlas Sound PD compression drivers. The integral “U-type” steel mounting bracket provides max- imum directional aiming flexibility and enhances installation capability when used outdoors or in industrial environments. 65° dispersion angle.
124 COMPRESSION DRIVERS
AT-PD60AT • Fully environment-resistant 60 watt driver for indoor or outdoor applications recommended for use in expansive and/or high ambient sound-level areas. The unit features a sound chamber, phasing plug and magnetic-structure components machined to optimum tolerances. Additionally the unit includes a built-in varnish impregnated, multi-tap 70 volt line-matching transformer. Corrosion-resistant terminal connections are protected by a transparent, impact-resistant plastic cover which provides strain relief for the interconnecting cable.
• Terminated in standard 1-3⁄8"-18" thread male couplings for use with screw-on horns.
