ALT72 Assistive Listening System

Ensure that the hearing impaired are full members of your audience
with the Drake ALT72 Assistive Listening System.

We Can Assist You With Meeting Federal Requirements
The Americans with Disabilities Act requires public facilities to provide assistive listening systems in a public setting. Drake’s ALT72 consists of quality, commercial-grade hardware that meets ADA requirements. The ALT72 utilizes the FCC designated assistive listening frequencies for hearing participants in schools, theaters, houses of worship, auditoriums, and other public facilities.

Why the ALT72 Assistive Listening System?
Drake’s ALT72 is a high-fidelity, wide-band FM system; the most flexible assistive listening system for both installers and users. It is superior to hard-wired or infrared systems which have severe limitations for outdoor use or applications requiring flexibility. The Drake ALT72 is easily integrated into existing audio systems without requiring structural modifications to the facility or special seating for a certain number of users.

This assistive listening system is manufactured by Drake, an American manufacturer of quality RF and satellite communications equipment for over 60 years.

The Drake ALT72 is a state-of-the-art assistive listening system. Background noise and poor acoustics can interfere with traditional audio systems, preventing the hearing impaired from fully participating in the presentation or program. The Drake ALT72 provides crystal-clear reception of audio, enabling even the hearing impaired better than front row audio participation.

The Complete Assistive Listening System
The ALT72 system includes one transmitter and two pocket-sized MR306A personal receivers with dual earbuds. Dual earbuds provide maximum amount of clear audio to the listener. Additional receivers are reasonably priced and sold separately to accommodate any size audience.

It’s As Easy As 1-2-3
Drake designed the ALT72 assistive listening system to be rugged, and with the operator and user in mind. The system is easier to use than any home stereo. Just set the transmitter to any of 10 channels, select the same channel on the personal receivers, and your message is heard by everyone. The pocket-sized personal receivers offer the same simplicity of operation as a pocket radio, plus a lock feature to prevent the user from accidentally changing the channel setting.

Now You Can Include Everyone
All members of your audience want to be full participants, and now they can be. Making audio accessibility has never been easier than with the Drake ALT72 assistive listening system.
