Atlas Sound BIA-100 Horn and PD75T Compression Driver Package

This Atlas horn driver package features the BIA-100 original reflex horn with a bi-axial design, twin air columns and exponential bell for wide-angle coverage with a linear frequency response. The horn provides excellent acoustic loading maintained to a 350 Hz low-frequency roll-off and optimizes delivery of high and mid-range signal levels. BIA-100 is designed for use with Atlas Sound PD Series compression drivers and models having 13/8" -18 male threads and 0.707" dia. throat openings. The easily-mounted horn features the labor-saving patented gimbal-mount bracket assembly (U.S. Patent # 4,325,529) which allows for directional positioning up to 180° vertically and horizontally. It includes a steel bracket, cast-mounting base and provisions for flange installation. The weather-resistant, non-glare matte black foam horn is resistant to resonance. The bracket assembly is finished in durable epoxy.

The PD75T compression driver is a fully environment-resistant 75 W driver for indoor or outdoor applications and is recommended for use in expansive and/or high ambient sound-level areas. This model features a sound chamber, phasing plug, magnetic-structure components machined to optimum tolerances, 2" voice coil and offers a plane wave frequency response of 100 Hz - 3.7 kHz. This unit, which is comprised of a transformer with 16 Ω bypass, will meet a variety of applications. The PD75T provides screw-type terminals for matching direct to the 16 Ω voice coil impedance and a built-in varnish impregnated multi-tap 70.7 V line-matching transformer. Corrosion-resistant terminal connections are protected by a transparent, impact-resistant plastic cover.
