Listen Technologies LS-60 User's Manual

Don’t miss a single sound. Listen.
Soundfield applications are areas where audio needs to be amplified for people to hear
better. This can be in a classroom, meeting room, training center or theatre. Studies
have shown that by boosting the audio levels of normal voices, you not only increase
retention by as much as 30%, but also reduce potential for voice strain and fatigue.
Wherever a large PA system is impractical, a Soundfield FM solution is likely the answer.
Employee Training
Listen’s line of Soundfield FM products deliver a carefully tuned system of components
that makes the process of specifying, ordering and using the system simple and straight
forward. A Listen FM system functions like a low power radio station that broadcasts
sound to receivers within range of the transmitters. This system is an easy way to deliver
interference-free sound to groups of all sizes ensuring that all participants, hear the
message clearly.
Don’t miss a single sound. Listen.
Classrooms
Listen’s easy to use and
ergonomically designed
equipment can fill a classroom
with crisp clear sound. This allows
the teacher to convey information
without voice strain or fatigue and
ensure that each student has the
opportunity to hear the message.
Your most vital assets are your employees and their
contribution to your organization. For your employees to be
as productive and efficient as possible their training is critical.
By providing your training center with a Soundfield system,
you can ensure that your staff understands and processes the
information more effectively, allowing them to contribute
more to your organization.
Meeting Rooms
When you assemble your company for monthly meetings, you
want to make sure that it runs smoothly. An important part of
this efficiency is that each participant can hear what is being
presented. A Listen system will amplify your speaker’s voice
above background noise giving you the full confidence of your
employees.
Overflow Areas

Be prepared in those instances when you call an
impromptu staff meeting and not everyone can fit into
your conference room. A Listen system allows you to
provide an overflow area to make sure your entire staff
can hear what is being presented.
Listen Soundfield FM System
Studies show that students learn up to
30% more in classes with audio
amplification. This means that the
classroom experience can be improved
for both teachers and students with
soundfield reinforcement. Vocal strain
is eased for teachers and students can
hear better. Overall, the learning
experience is improved.
Effective instruction doesn’t
have to be impaired by a noisy
environment. Soundfields allow
instructors to direct their classes
with a normal speaking level and
students receive valuable
instruction clearly.
