Maxim III
a brief word about infrared
Infrared is a light ray that is below the visible
spectrum, just like the soun extends beyond your
hearing ability. An example of infrared transmission
is the remote control for your TV set. When a button
is pressed, a beam of infrared light is emitted by
a Light Emitting Diode (LED) from the remote
control. It is detected by a receiving diode in your
TV set. When you press a certain command on your
control, the internal electronics cause the infrared
light to flicker in a programmed sequential pattern
(called modulating the light beam). The modulated
infrared beam is detected by the receiving diode
and is electronically decoded. The decoded signal
activates the circuitry to perform the command
function on your TV set.
So how doe s this apply to the i nfrared comm unication
system you are about to start using? The
microphone/transmitter has several Light Emitting
Diodes (LED) that emit infrared light beams to the
sensor located in the corner of the room. Now
when you talk into the microphone, the microphone
element modulates the light beam, causing it to
flicker in sync with your speech. The sensor detects
the sequential signal and the electronic circuitry in
the Maxim III converts that sequential signal into a
line level analog audio signal. Now that audio signal
can be fed into an amplifier. The amplifier magnifies
the electronic signal and sends it to the speakers.
This causes the speaker cone to move in sync with
your voice. The speaker replicates your voice and
disperses your voice evenly throughout the room.

IR transmission
The IR transmitter
transmits directly to the
sensor. However; due to
the strength of the IR
transmitter, the infrared
signal will bounce off the
walls, ceiling and floor for
reception thus providing
continuous connectivity
throughout the room.
Benefit: total freedom
of movement within the
room with no restriction
of orientation.
Infrared will not
penetrate a solid surface
thus preventing any
transmission from
going out of the room.
“What’s said in
the room, stays in
the room”.

Maxim III
product description
The Maxim III is an infrared wireless microphone
system that can be added to any sound system.
It can be a supplement to an existing multi-media
system to expand it's utilization to provide voice
reinforcement.
The addition of a Maxim III system to your multimedia system will transform your classroom
sound system into a totally hands free voice
re-enforcement system, resulting in reduced voice
fatigue, enhanced student listening and improved
student learning. The wireless function permits
360° connectivity throughout the classroom
regardless of body position or orientation.
The system is comprised of an infrared detecting
sensor(s) installed in the ceiling. The sensor
collects the IR wireless signal from the microphone/
transmitter and sends a composite signal to the
receiver. The receiver transforms the composite
signal into an analog audio signal which is fed to
the multi-media amplifier. The amplifier powers the
speakers for even voice reinforcement throughout
the room.
The microphone / transmitter can be the Sapphire
or Handheld. The rechargeable batteries will
provide 6 – 8 hours of service per charge. The dropin charger will recharge the batteries overnight,
ready for another day’s use.
Reliable
performance.
Use with
confidence.

Maxim III system
The Maxim III system is comprised of a microphone / transmitter, either the
Sapphire (IRT-60), or Handheld (IRH-35) for voice transmission to a ceiling
sensor (ICS-55) that sends the signal to the receiver / amplifier (IMA-520).
The receiver/amplifier processes the signal and produces an analog signal of
your voice for output to the sound field speaker system.
