The LT-84-D ListenIR 2-channel transmitter-radiator from Listen Technologies is Dante compatible through the use of the LA-465 Dante adapter and provides venues, businesses, government agencies, and more with an affordable and easy-to-use assistive listening solution. The LT-84-D can transmit a clear, reliable signal across 2,787 square meters (30,000 square feet) and is designed for mid-sized spaces such as boardrooms, courtrooms, classrooms, and other venues.
Features expansion radiators (LA-141) with delay compensation to help prevent signal cancellation dropouts. Up to four (4) LA-141 expansion radiators can be added for additional coverage when mounted within 30.48 m (100 ft.) of the unit. The transmitter-radiator can also transmit on four different frequencies: 2.3 MHz, 2.8 MHz, 3.3 MHz, or 3.8 MHz, providing flexibility during installation and setup.
With included mounting hardware, flexible frequency selection, Dante compatibility, and multiple input options, the Listen Tech LT-84-D provides an infrared assistive listening solution for businesses and venues. A single CAT-5e cable carries both power and signal to LA-141 expansion radiators, supporting an expandable system design.
