Personalize. Simplify. Customize.
Whether in a theater, house of worship, or at a sporting venue, individuals want to experience every word and every moment.
That’s what they came for, and they deserve to participate by hearing every single word.
Listen’s line of stationary FM products deliver a carefully tuned system of products that makes the process of specifying,
ordering, installing and using the system simple and straight forward. A Listen FM system is a low power radio station that
broadcasts sound to receivers within the range of the transmitter. A wide range of portable and stationary receivers allow you to
customize your system to your speci c needs. Listen products deliver broadcast quality audio and are simple to use.
Don’t miss a single sound. Listen.
Personalize
Listen’s vision is to deliver a personalized, enriching
auditory experience in any setting. Consider attending a
lecture and not being able to fully understand what is being
said. With a Listen system, every word can be heard and
understood. What if the lecture is in English and you can
only understand Spanish? The same technology can deliver
the interpreted language directly to your ears. When you
can hear and understand – the experience truly becomes
personal!
Simplify
Listen is committed to keeping it simple. You will nd
products that are easy to use and a company that is easy to
work with. Listen thinks through the ner details in the
design and production of products – for you the customer.
From pre-setting a default frequency on a transmitter so that
it can be used right out of the box to channel displays on
both the transmitter and receiver – the use of Listen’s
products is e ortless. Listen’s full-time technical support
team is passionate about what they do and you can depend
on them to solve any equipment issues with con dence.
When you can easily use Listen products with the support
you need – the experience truly becomes simple!
Customize
One size does not t all. Listen systems are designed to speci cally t your needs. While Listen’s systems are designed for simplicity, feel free to
inter-change or add components to create the right system for you. Listen’s team is ready to assist you with identifying exactly what you need.
When you can build the system that makes sense for your circumstances – the experience truly becomes custom!

Don’t miss a single sound. Listen.
A Listen Stationary FM system can do more than you think. While a Listen system can deliver crystal clear sound to a person with a
hearing impairment, it can also be used in other ways including:
• Language interpretation.
• Wireless speaker/receiver in nurseries, locker rooms, o ces.
• Wireless audio distribution to remote rooms.
• Remote cueing.
Classrooms
Sports Venues
Whether it’s a 1,000 person high school gym
or a 100,000 person baseball stadium, a Listen
system can deliver sound to every seat in
the facility. Sport enthusiasts, press and the
athletic competitors can all enjoy the bene ts
of a Listen system.
When you can hear better, you learn more. A Listen system
can deliver the instructor’s voice or the voice of an interpreter
directly to the student’s ears. The end result is improved grades
and instructors who are less fatigued because they don’t have
to speak loudly.
Theaters
Have you ever been experiencing a live play and asked your
partner “what did she just say?” We all have some level of
hearing impairment and sometimes we sit in a seat where
the sound is not as clear as we would like. A Listen system
delivers the voice of the actor directly to your ears.
Places of Worship
The primary message in a worship service is delivered in
the form of sound. A Listen system can ensure that every
individual can fully experience the service. You can use Listen
products for auditory assistance and for language
interpretation. You can also place a speaker/receiver in the
nursery or in an over ow area.

Choosing the right antenna for your application is critical to ensuring adequate transmission coverage. There are two types
of antenna – unit mounted and remote mounted. Unit mounted antennas can be mounted through an opening on top of
the unit or on a rear BNC connector. You need to match the frequency range (either 72 or 216MHz) for your application to
assure the purchase of the right antenna. Use the table below to make your selection. All remote antennas include 25 ft.
