Federal Signal Models AM300GCX and AM302GCX are rugged, transformer coupled, re-entrant speakers for use in public address or paging applications. These speakers feature rugged cones and projectors constructed of spun aluminum. The wiring connections are enclosed in a dust- and moisture-proof, die-cast aluminum compartment. All external surfaces are finished with a gray powder coat paint.

Power handling for the AM300GCX is 15 watt and the AM302GCX is rated for 30 watt. There are transformer taps at 15, 9, 3 and 1.5 watt in the AM300GCX and 30, 15 and 9 watt in the AM302GCX. Both speakers are designed for use in 25 or 70Vrms distributed systems. Both models are UL and cUL Listed for Class 1, Division 2, Groups A, B, C, & D; Class II, Division 2, Groups F & G; and Class III environments. The design and seal of the speaker assembly and housing have been tested and approved by UL for Type 4X requirements.

Four screws inserted through the metal tabs located at the side of the housing make for a simple wall mount. The bottom of these speakers contains two 1/2-inch conduit openings in the base of the housing to accommodate inbound and outbound audio wiring. The unique shape of the speaker projectors provides an impressive 60º sound dispersion pattern. The projectors are held in position with a Teflon coated lock ring that can be rotated 180º in order to obtain the desired sound distribution.

The AM300GCX and the AM302GCX can be used with the AudioMaster® CTS series amplifiers and the AudioRouter™ to complete an industrial grade public address system.
