A single unit provides up to 30,000 ft² (2787 m²) coverage area with LR-4200-IR/LR-5200-IR receivers or 7,500 ft² (697 m²) with LR-42/LR-44 receivers in single channel mode, ensuring that the entire room has coverage without gaps or null spots.

The LT-84 is the first IR system with Expansion Radiators (LA-141) that implement delay compensation to reduce signal cancellation drop-out.

It is the only two-channel Transmitter-Radiator with up to four frequencies; 2.3 MHz, 2.8 MHz, 3.3 MHz, or 3.8 MHz, providing flexibility in the field and eliminating the need to purchase a specific frequency based transmitter-radiator.

The LR-4200-IR/LR-5200-IR receivers operate on lithium-ion batteries and are charged via a mini-USB cable that connects to a plug-top PSU or a twelve-slot charging rack.

Each receiver has two headphone sockets that can also be used to connect the innovative LA-430 neck loop.

Once connected the neck loop acts as a lanyard for the device.

The neck loop also has an integrated headphone socket, enabling the connection of a single earphone so the receiver can then be used by a non-hearing aid wearer.
