Product Overview
At the core of the Listen Technologies ListenIR system lies the LT-82 single-channel transmitter, engineered for Dante compatibility facilitated by the LA-465 Dante adapter. Versatile in function, the LT-82 operates seamlessly in mono or stereo modes, facilitating the transmission of your audio signal while supplying DC power to one or more LA-140 infrared radiator/emitter units via standard CAT-5 cabling. Furthermore, these units can be integrated to furnish up to four (4) channels of mono or stereo audio, thereby broadening the system's utility across various applications.
