  Infrared Slave 165 Diode Standard Emitter, Model: EX-PS3  

Infrared Slave 165 Diode Standard Emitter - EmitterThe EX-PS3 Emitter/Slave is a member of the popularAudex® family of 95KHz broad band transmitters. Featuring 165, eighty degree high power diodes, this emitter produces a broad, deep pattern well suited to meeting rooms, courtrooms, auditoriums, movie theaters, and other entertainment facilities, and out-of-door venues in theme parks and other public facilities. Mounted at a height of 15’ to 30’, the coverage pattern resembles a top, with an area up to 6,000 square feet. Using theAudex® COC circuit, this unit emits with 92% efficiency, insuring maximum coverage for all applications. The circuit adjusts diode drive levels due to varying ambient temperatures. This feature, coupled with the overall light producing capabilities, and the efficiency of the REC-T3 neckloop receiver, allowsAudex® to offer effective infrared performance even out of doors in daylight. This means multiple areas in a park, auditorium, university, or convention center can use one frequency and therefore one set of receivers carried from venue to venue by the hearing impaired patron. Since theAudex®LightLink, REC-T3 receiver is resistant to electronic ballast lighting interference, all of the advantages of 95KHz broadband technology is available with this emitter system for courts, universities, and other government facilities.

Infrared Slave 165 Diode Standard Emitter - Coverage PatternIn addition to its impressive light generating capabilities, the EX-PS3 offers flexibility not found in other brands of infrared. If AC power is not available at the emitter location, this unit can receive both signal and power through its “Expansion Input” jack. One, three-conductor speaker wire originating at a EX-B-3 base, or Ex-BEX-6 Expansion, located in the control room, can provide both signal and power, totally eliminating the need for an AC outlet at the emitter. This makes retrofitting facilities easier and less costly.

Infrared Slave 165 Diode Standard Emitter - Rear ViewIf AC power is located within 20’ of the emitter, signal only can be carried to the “Expansion Input” jack. Power must be supplied locally at the “24V Expansion Input” jack. The “Expansion Output” jack can send signal, or signal and power to another EX series emitter, making the daisy-chaining possibilities endlessly flexible. 

With these features, no other brand of infrared emitter can offer anything close to the cost effectiveness of this family of products!
