You can enhance your LT-84 Infrared Transmitter/Radiator combo system with the high-quality LA-141 Expansion Radiator from Listen Technologies. This innovative device is specifically designed to expand the functionality and coverage area of your LT-84 system, providing an uninterrupted, superior listening experience.
The LA-141 Expansion Radiator allows for the addition of up to four units to your LT-84 system, significantly increasing the coverage area. With LR-4200-IR/LR-5200-IR receivers, you can achieve additional coverage up to 30,000 square feet (2,787 square meters). Alternatively, with LR-42/LR-44 receivers in single-channel mode, you can extend the coverage up to 7,500 square feet (697 square meters).
This efficient and reliable expansion radiator is powered and connected via a single CAT-5e cable, ensuring a streamlined setup process. The included mounting hardware and single-cable design simplify the installation, making it a breeze even for those with limited technical knowledge.
The LA-141 Expansion Radiator is capable of receiving four mono carrier frequencies of 2.3, 2.8, 3.3, and 3.8 MHz over a proprietary RJ-45 Expansion Link. It also features an automatic deactivation of the IR emitting LEDs after 15 minutes of inactivity, conserving energy and extending the lifespan of the device.
When connected to a Trans-Radiator, the LA-141 ensures a system audio performance of 60 dB SNR or better, a THD of less than 2%, and a frequency response of 63 Hz to 15 kHz, +/- 3db. The device also provides delay compensation via two rotary four-position switches for up to two audio channels.
The LA-141 Expansion Radiator is a durable and reliable addition to your LT-84 system, allowing for an enhanced audio experience and expanded coverage area.
