enhancement system in the classroom provides better
classroom management and fewer discipline issues
"I don't have to repeat instructions."
Hearing is believing
With sound enhancement in
the classroom, everyone can
participate and hear what
the teacher is saying.
Microphones provide access
to the teacher from anywhere
in the classroom, without shouting
or disrupting instruction.
Instruction
within reach
With the pendant microphone,
teachers can be heard and
control audio from anywhere
in the classroom.
The benefits are clear
When teachers use a microphone
system during instruction, they have
less voice fatigue, more energy, and
students feel more included. Teachers can
speak in a normal tone and everyone in the
classroom hears what is stated.
Both hands remain free
for writing and sharing
lesson details.

Panasonic infrared wireless microphones offer a new level of performance
The pendant microphone provides
convenient hands-free functionality
The pendant microphone integrates the infrared emitters, microphone
and processor into an all-in-one, easy to use unit, for cable free operation.
Easy to wear, easy to use
In contrast to conventional lapel microphones, the WX-LT350 has a built
in microphone thus eliminating the need for a hard wired microphone.
The WX-LT350 is suspended around the neck with a lanyard, allowing
for a comfortable, almost un-noticeable wireless transmitter.
The handheld microphone is lightweight
and easy to use
The innovative design of the handheld microphone
provides for trouble free operation by placing the emitting
diodes just below the microphone, preventing them from
being blocked by the users hand.
Light, comfortable design
prevents speaker fatigue
The sleek design of the handheld microphone,
weighing only 105 grams (0.23 lbs.),
utilizes a single 'AA' NiMH rechargeable battery, and
is easy to use for presenters, audience members,
and the small hands of students.
Emitter
Adjust volume from the microphone itself
The WX-LT350 is equipped with remote volume control of the teacher/pendant microphone
and the student/handheld microphone which prevents the teacher from having
to adjust volumes at the amplifier thus not having to stop instruction.
Multimedia levels can be controlled with a compatible receiver.

Broadcast sound from PCs
or other audio sources
When the microphone is connected to a PC
or other audio source, the sound can be broadcast
via the infrared wireless system.
Easy to install
The dome infrared sensor covers
360 horizontal degrees
A single WX-LS100 Infrared Sensor provides
360 horizontal degrees of coverage, more than sufficient
for standard classroom areas.
Using the Infrared Sensor Coupler WX-LC10, up to four
sensors can be used to support expanded educational
spaces.
