Just imagine the power of a high-quality, durable, and innovative audio solution in your hands. The LT-84 ListenIR 2-Channel Transmitter/Radiator Combo, a patented product (Pat. 9,712,246) from the reputable Listen Technologies, is designed to provide venues, businesses, and government agencies with a user-friendly and affordable assistive listening solution.
This compact device offers double the infrared power and up to six times the coverage area compared to similar products on the market. It can transmit a crystal-clear, reliable signal across an impressive area of 2,787 square meters or 30,000 square feet. This extensive signal range ensures that users in any mid-sized space, from corporate boardrooms to bustling courtrooms, can enjoy an uninterrupted, superior audio performance.
The LT-84 is the first of its kind in the infrared assistive listening systems to feature expansion radiators (LA-141), providing delay compensation to prevent any signal cancellation dropouts. You can add up to four (4) expansion radiators (LA-141) to the system for additional coverage, provided they are mounted within 30.48 meters (100 feet) from the unit.
What sets the LT-84 apart is its unique ability to transmit on up to four different frequencies (2.3 MHz, 2.8 MHz, 3.3 MHz, or 3.8 MHz). This flexibility simplifies setup and operation, eliminating the need to purchase separate, frequency-specific transmitter-radiator units.
The LT-84 comes with included mounting hardware, flexible frequency selection, and input connectivity, making it an ideal solution for adding infrared assistive listening capabilities and ADA compliance to your business or venue. Experience the difference with the LT-84 ListenIR 2-Channel Transmitter/Radiator Combo, a testament to Listen Technologies' commitment to superior audio solutions.
