The LT-84T-01 ListenIR TAA 2-Channel Transmitter/Radiator Combo(Pat. 9,712,246) from Listen Technologies provides venues, businesses, government agencies, and more with an affordable and easy-to-use assistive listening solution.
Offering twice the IR power and up to six times the coverage area of similar products, the LT-84T can transmit a clear, reliable signal across 2,787 square meters (30,000 square feet). This signal range ensures that users in any mid-sized space, from the boardroom to the courtroom and beyond, enjoy an uninterrupted audio performance.
In addition, the LT-84T is the only two-channel transmitter-radiator that can transmit on up to four different frequencies (2.3 MHz, 2.8 MHz, 3.3 MHz, or 3.8 MHz). This flexibility in the field makes setup and operation even easier, while also eliminating the need to purchase separate, frequency-specific transmitter-radiator units. With TAA-compliant configurations, the LT-84T is manufactured in countries eligible under the Trade Agreements Act and aligns with FAR 52.225-5 requirements.
With the included mounting hardware and the flexible frequency selection and input connectivity, the LT-84T is an ideal way to add infrared assistive listening capabilities and ADA compliance to your business or venue.
