Frequently Asked Questions

Why choose infrared over RF or Wi-Fi?
Infrared audio stays within the walls of a room, so the LS-91-01 is preferred where signal containment and confidentiality matter, such as courtrooms and boardrooms.

How large a room will it cover?
It provides coverage up to 30,000 ft² (2,787 m²) and is designed for venues of up to 50 seats. Larger or irregular rooms may require additional radiators.

Is it compatible with hearing aids?
Yes. Integrated neck loops and lanyards are compatible with T-coil (telecoil) equipped hearing aids.

Can we add more receivers later?
Yes. The included 12-unit charging tray makes it easy to store and charge additional LR-4200-IR receivers as needs grow.
