PD-60A HIGH EFFICIENCY 60-WATT COMPRESSION DRIVERS PD-60AT FEATURES Outstanding sound reproduction and power-handling for signaling, music and public address systems Extended frequency response range for Optimum intelligibility 60 watt power rating Environment-resistant construction for indoor/outdoor use Offered with or without transformer APPLICATIONS Atlas Sound Models PD-60A and PD-60AT are versatile, 60 watt, high power, compression drivers designed for use in conjunction with Atlas Sound large format horns (Models CJ-46, BIA-100, DR Series) or other similar equipment. Drivers provide maximum efficiency and extended heavy-duty performance. Combined with Atlas Sound horns, PD-60A Series Models offer quality and durability to assure optimum penetration and excellent intelligibility in profes- sional and commercial audio systems where sound projection and frequency response are demanded. PD-60A Series drivers will provide powerful audio or signal reproduction with supe- rior wide-range fidelity. Units are ideal for commercial sound, signaling and public- address systems in applications such as manufacturing, recreation and sports facilities, exhibit halls, commercial centers, ship- ping and transportation terminals, malls, storage areas and warehouses, etc. GENERAL DESCRIPTION Models PD-60A and PD-60AT are fully environment-resistant 60 watt drivers for indoor or out- PD-60A / PD-60AT door application and are recommended for use in expansive and/or high ambient sound-level areas. Models feature sound chamber, phasing plug, magnetic-structure components machined to optimum tolerances, 2 voice coil and offer a plane wave frequency response of 100 - 3,700 Hz (+5dB). This series, which is comprised of a 16-ohm (PD-60A) and transformer (PD-60AT) versions, will meet a variety of applications. Model PD-60A provides screw-type terminals for matching direct to the 16 ohm voice coil impedance. The PD-60AT features a built-in varnish impregnat- ed, 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. Models PD-60A and PD-60AT are terminated in standard 1.375 18 thread male couplings for use with screw-on horns, or with Atlas Sound Model DA-FH and YDA-TH adapters for bolt-on large format horns. Diaphragms are replaceable with appropriate equipment. Internal components are enclosed within protective die-cast housing and finished in grey baked epoxy. SPECIFICATIONS POWER PLANE WAVE LOW FREQ.
