The Federal Signal Model AMR6 is a high–quality ceiling speaker for public address and music in industrial, municipal and commercial office environments.

Power handling for the AMR6 is eight watts with transformer taps at 8, 4, 2 and 1 watts. The AMR6–2570 operates in 25 or 70Vrms systems and the AMR6–100 operates in 100Vrms systems.

The speaker is designed to mount flush in a ceiling or wall cavity. Adjustable "L" shaped clamps offer the flexibility of mounting to any surface thickness from 1/4" to 1–1/2". The AMR6 is suitable for use in air handling spaces when used with the Model R6BB Back Box and R6TB Tile Bridge.

Construction materials were selected to provide years of service in demanding conditions. The speaker frame is flame–retardant ABS that meets Underwriter's Laboratories requirements for Flame Class V–0, 5VA. The speaker cone is constructed of polypropylene and the surround material is a phenolic impregnated cloth, rather than the traditional paper structures.

The AMR6 offers a wide frequency response of 110Hz to 20,000Hz that reproduces a full range of voice, music and electronically generated tones. To achieve these impressive results both a woofer and a neodymium tweeter are utilized. Neodymium is a rare earth metal known for high energy in compact sizes.
