HamiltonBuhl Assistive Listening System

Most of us take hearing for granted. Sound, such as speech, occurs somewhere in the
environment around us, and we, quite simply, "hear” it. And,
It is well-recognized that hearing is critical to speech and language development,
communication, learning and social interactions.

Breakdown learning, communication and social
barriers with the HamiltonBuhl ALS700 Assistive Listening System. Separate the sound that your audience wants to hear
from the background noise, and deliver it at the right amplification level,
directly into the individual’s ear.

Individuals utilizing the ALS700 receivers will
easily achieve the required volume increase and gain the same level of
understanding without making it too loud for everyone else.

A single ALS700 System transmitter can serve an
unlimited number of receivers in a 150 foot range! Fully ADA compliant, the
ALS700 is the ideal assistive listening system for any environment: school, movie theater, house of worship, performance
theater and more.
