Quantum II
a brief word about infrared
Infrared is a light ray that is below the visible
spectrum, just like the sound spectrum 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 does this apply to the infrared
communication 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 Quantum II 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”.

Quantum II
product description
The Quantum II is an infrared wireless microphone
sound system. It is the nucleus of the classroom
sound field system which provides optimum voice
reinforcement.
The addition of a Quantum II sound system will
transform your classroom 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. The sensor collects the IR wireless signal
from the microphone/transmitter and sends a
composite signal to the mixer/amplifier. The
receiver transforms the composite signal into an
analog audio signal which is fed to the Quantum
II mixer. An additional audio sources, such as;
computer, DVD, VCR or Projector can be plugged
in to the Quantum II. The AUX IN level controls the
individual audio input. The audio will then be fed to
the speaker in the column for voice reinforcement
throughout the room.
On the front panel of the Quantum II, there is a
3.5mm output jacks for interface with an assistive
listening system (ALS) or lesson capture (LINE
OUT).
The microphone / transmitter can be one or two
Sapphire Pendants or Handhelds. The rechargeable
batteries will provide 6 – 8 hours of service per
charge. The drop-in charger will recharge the
batteries overnight, ready for another day’s use.
Reliable
performance.
Use with
confidence.
