Our tech guy thought he had a hearing assisted system invented but it requires local radio frequencies and they all appear to be taken by local pirate stations.
Any opinions of a simple system for our twin.

Today, most prefer the IR systems. Analog radio systems have a limited number of channels (frequencies available), are prone to interference, and the signals can be pirated by a receiver outside the theatre.

A "home brew" radio system would also need to comply with FCC Part 15 (or other government agency) guidelines.

Also AM and FM transmitters don't actually meet the ADA requirements in all cases
The use of the IR type systems is the safest bet

Hey Ky,
Thanks.
Do they sometimes have deals or used equipment?

USL (Ultra Stereo, Inc.) also good ADA compliant infrared systems available for auditoriums of different sizes. Infrared versus RF means no switching frequencies or dedicating particular headsets to specific auditoriums. They simply and without adjustment receive the intended program without problems.

If on the otherhand, your wireless headsets are getting more use by a projectionist or manager for spot checking operations from the lobby, RF is going to be the only choice as infrared light will obviously not pass through walls. Williams Sound makes an ADA compliant RF system with simple frequency selectors that can correspond to auditorium numbers.
