Introduction
Thank you for choosing the Nady ALD-800 wireless RF personal listening assistance system,
we know you will be very pleased with its performance and features.
The Nady ALD-800
is the most cost-effective way to provide high quality listening as sis tance in compliance
with the Americans with Disabilities Act (ADA), which requires public facilities such as
movie theatres, etc. to make listening assistance systems available to their audiences.
The system is designed to be very easy to use and requires no installation.
The ALD-800 is specifically designed to be installed quickly and easily by virtually anyone.
In addition to its ease of use, the ALD-800 provides outstanding sound quality. The system
consists of one wireless transmitter and one or more pre-tuned portable wireless receivers.
The transmitter features eight factory switchable channels; the re ceiv ers are single channel
units that operate on one of eight channels in the 72-76 MHz band, with wide band
modulation for quality audio.
Unlike infrared listening systems, the ALD-800 can be used outdoors and indoors in bright
light without affecting performance.
The ALD-800 is perfect for virtually any application, from a small meeting room, or a
mid-sized house of worship, to a large cinema. The ALD-800 provides high quality hear ing
assistance to any number of audience members, without seating restrictions.
The ALD-800 system has a wireless operating range of 300 feet. The transmitter connects
to the line out or tape out from a venue’s existing sound system, and broad casts the audio
as an FM radio signal. The transmitter can also be used with an optional mi cro phone.
Audience members who desire listening assistance use a pocket size Nady ALD-800
receiver with adjustable volume control and er go nom ic, high performance earphones.
The ALD-800 system is expandable—one transmitter will provide audio to a limitless
number of receivers.
