The ALS-600 Wireless VHF Assistive Listening System from Hamilton Buhl is designed to provide quality listening assistance in compliance with the ADA (Americans with Disabilities Act), which require public facilities with audio systems to make listening assistance available to their audiences.

This system is configured with a wireless transmitter and 6 portable wireless beltpack receivers. A single transmitter can serve an unlimited number of receivers in a 300’ (91.44m) radius.

This system is configured with 1 channel in the 72 to 76 MHz band and can be operated in indoor or outdoor environments without affecting performance. It connects to the line out from a tape player or from an existing sound system and broadcasts the audio as an FM radio signal.

This system offers high-quality auditory reception without seating confinements, which makes it suitable for any applications from small classrooms and boardrooms to auditoriums and sanctuaries.
