Assistive Listening Systems
The TX-37A Transmitter is the core of Gentner Assistive
Listening Systems. The transmitter utilizes leveling multi-
band compression, peak limiting, and the patented Aphex
Aural Exciter®to process audio for maximum
intelligibility and loudness. While other assistive listening
transmitters simply increase volume, Gentner’s TX-37A
actually enhances the sound quality to increase audio
clarity at louder levels. It also eliminates the potential for
clipping and overmodulation.
The transmitter can be set to 37 different frequencies,
allowing you to use multiple transmitters in one location
while reducing the possibility for audio interference. This
is especially useful for education and simultaneous
translation applications. Its universal input stage accepts
audio from mic, line, or speaker levels producing
exceptional audio quality at all levels. Connection is made
to the existing audio system via a tape or mixer
auxiliary output.
The transmitter is designed with a compact, steel, 1/2
rack unit chassis. The shielded steel chassis protects the
unit from damage and keeps out hum as well as other
system noise. Gentner provides a rack mount kit* (sold
separately) to store the transmitter in a standard 1U
rack space.
