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.

assembly and installation

Mounting the Quantum II on the wall, please review the following guidelines.

• Selecting the most appropriate location for the Quantum can be the

most challenging. Every room is a little different, but in general the most

functional location is installing it on the front wall off to one side or the other

approximately from either side wall.

• An alternate choice would be on either side wall, located approximately ¼

the distance from the front of the room.

NOTE: Be conscious of an AC outlet requirement for power.

• Once you’ve decided where to mount the Quantum II, hold the ‘U’ bracket

straight up and down against the wall with bottom of the bracket approximately

5-6 feet above the ﬂoor. Using a level to assure true vertical orientation, mark

the two mounting holes.

• If installing onto a drywall, drill two ¼” holes and insert a molley bolt

provided. With a #2 Phillips head screwdriver, mount the wall bracket.

• If installing into a wood or like material, use two sheet metal screws with

washers to mount the bracket to the wall.

• For concrete wall, you’ll need to acquire and install a plastic insert for a # 8

sheet metal screw and install accordingly.

• With the bracket mounted, route the plastic wire tie through the two tab

holes. Hold the power supply onto the two raised tabs with the AC plug end

toward the ﬂoor. With the power supply resting on the pegs, tighten the wire

tie thus securing the power supply to the bracket.

• Insert the DC plug into the power input jack and place the Quantum II into

the bracket, secure each end with the bolt and washer provided.

• Orient the Quantum with center pointing diagonally across the listening

area.

• Plug the power cord into an AC outlet

The Quantum II can be operated as a free stance system on a speaker stand.

To use in this mode of operation:

• Locate the system off to one side in the front of the room. Point the front

of the unit toward the center of the listening area. Find an AC outlet and plug

the system in.

• Side wall location is also acceptable. Locate unit on either side about ¼

from front of room. Point the front diagonally across the listening area. Locate

an AC outlet and plug it in.

quantum II controls

• Channel A turns power “on/off” (red LED

indicator) and adjusts the volume of the IR

microphone assigned to it. Normally the Pendant

transmitter is assigned to channel A. When the

transmitter is turned “on” a green LED will light,

indicating that an IR signal is being received from

the transmitter.

• Channel B also turns power “on/off” and adjusts

the volume of the microphone assigned to it.

Normally the handheld microphone is assigned to

channel B. When the transmitter is turned “on” an

amber LED will light indicating an IR signal is being

received from the transmitter.

• Tone control adjusts the tonal quality of the

sound. You will feel a center indent, turn CCW will

boost the bass and turning CW will extenuate the

high frequencies.

• Aux input jack (3.5mm) facilitates connecting the

output of a DVD, Video Projector, ipod, computer

and amplifying its signal through the Quantum. The

volume can be controlled with the adjacent knob.

• Line output jack (3.5 mm) provides a composite

line level output; it can be used to connect to a

personal FM assistive listening system or as an

output to a recording device. The small knob

adjusts the output level to match input of the

device connected.

• External speaker output connector is located

adjacent to the power plug. An unpowered external

speaker can be connected to the Quantum for

additional coverage. A companion unpowered

Quantum would be the speaker of choice.

infrared microphone/transmitters

The infrared microphone/transmitter is comprised of a microphone input, signal processing

circuits and several emitting diodes that transmit the vocal signal to the sensor.

The microphone/transmitter can be the Sapphire or Handheld. The rechargeable batteries

will provide 6–8 hours of service per charge. Place the microphone/transmitter in the charger

for overnight charge and it will be ready for another day’s use.

The drop-in battery chargers are speciﬁcally designed to recharge lithium & NiMH batteries

at an optimum rate for maximum operating capacity and extended service life. Charger will

automatically start charging the batteries upon insertion and will shift to a maintenance

charge when batteries are fully charged.

The Sapphire’s vocal clarity is unsurpassed. Its

high level output is achieved by the unidirectional

(Cardioid) microphone and a unique free air

suspension system. With a built-in breath ﬁlter, the

Sapphire can function as a pass around hand mic.

The strategic alignment of the emitting diodes

assures reliable connectivity throughout the room

without static or drop out.

With a tap on the power button, the microphone

is muted for private conversation—tap again to

restore to normal operation. The auxiliary input

allows wireless playback of your iPod™ through the

Sapphire. A three position slide switch provides

selection of low, medium, or high microphone

sensitivity.
