 Infrared 165 Diode Master Theater Emitter, Model: EX-PS3-T6  

Infrared 165 Diode Master Theater EmitterThe EX-PS3-T6 Expandable Infrared Master/Slave Emitter/Transmitter is a member of the popular Audex® family of 95kHz broadband 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 and public facilities. Mounted at a height of 15’ to 30’, the coverage pattern resembles a top, with an area up to 5,000 square feet. Using the Audex® COC circuit, this unit emits with 92% efficiency, insuring maximum coverage for all applications. The circuit adjusts diode current drive levels due to varying ambient temperatures. This feature, coupled with the overall light producing capabilities allows Audex® to offer the most effective infrared performance. 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 patrons. All of the advantages of 95kHz broadband technology is available with this emitter system for courts, universities, and other government facilities.

Infrared 165 Diode Master Theater Emitter - Coverage PatternIn addition to its impressive light generating capabilities, the EX-PS3-T6 offers flexibility not found in other brands of infrared, particularly for use in movie theaters and hotel meeting rooms. Inputs directly to the EX-PS3-T6 when used in the master (INT) mode, include line level and up to six, mixed speaker level inputs. In a movie theater the audio input can be taken directly from the speaker system behind the screen eliminating the need to run additional audio cables. When the unit is in the slave (EXT) mode, it receives its signal and power, or signal only from the previous emitter (EX-Series) or base unit (EX-B-3). Power can be provided locally by plugging into the Expansion Input power jack. In the master (INT) or slave (EXT) setting the Expansion Output jack allows signal or signal and power to be provided to additional emitters through 18 ga. three conductor cable. The daisy chain can be as long as needed, allowing for coverage of any sized area. In hotels, large ballrooms that are divided into a combination of smaller rooms using air walls, can be served by placing one or more EX-PS3-T6 in each divided room, each connected to the speaker system in that room. When the airwalls are in place each unit functions as a master receiving its audio from the speaker system in the room. When the air walls are removed the units are switched to slaves receiving their audio from the one master through the expansion ports in the daisy chained system.

Infrared 165 Diode Master Theater Emitter - Back Panel ViewPermanent mounting requires only one installer using a special Omni-Mount (RPA-BKT-O) bracket attached to the back or end of the unit by internal permanently fixed threaded nuts. This bracket allows rotation in two planes making precise focusing quick and easy. Fifteen red LED’s viewed from the louvers on the bottom of the unit provide easy monitoring of the infrared emitting diodes. Custom Colors are available at a small additional cost. 

With its combination of unique features, the EX-PS3-T6 is a leader in infrared technology for hearing impaired people!
