The LT-84T-01 is a high-performance, TAA-compliant infrared transmitter and radiator combo designed to provide dependable assistive listening in small to mid-sized commercial and government facilities. Combining both the transmitter and radiator into a single compact unit, it simplifies installation while delivering powerful infrared coverage of up to 30,000 square feet (2,787 m²). It is an ideal solution for classrooms, boardrooms, courtrooms, conference centers, houses of worship, theaters, and other venues requiring ADA-compliant assistive listening.
Designed for maximum installation flexibility, the LT-84T-01 supports two-channel transmission and allows users to select from four infrared carrier frequencies (2.3, 2.8, 3.3, or 3.8 MHz) without requiring different hardware models. Multiple audio input options make system integration simple, while the high-power infrared output provides clear, gapless audio coverage throughout the listening area for consistent speech intelligibility and audio quality.
As a Trade Agreements Act (TAA)-compliant solution manufactured in approved countries, the LT-84T-01 meets government procurement requirements under FAR 52.225-5. The system includes mounting hardware, power supply, Phoenix connectors, assistive listening signage, and a quick-start guide for fast deployment, making it an affordable, scalable, and easy-to-install infrared assistive listening solution.
