a brief word about infrared

Infrared is a light ray that is below the visible spectrum, just like sound 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.

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 amplifier 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.

"What's said in the room, stays in the room".

Infrared will not penetrate a solid surface thus preventing any transmission from going out of the room.

system overview

The Matrix is an amplifier, audio mixer, and infrared wireless microphone receiver in one. It is the hub of the classroom audio system as various media inputs can be connected to it, so that all classroom audio can be amplified and distributed clearly through the speakers. The addition of microphones provides voice reinforcement for the teacher and students alike.

The Matrix 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-120). The receiver/amplifier processes the signal and produces an analog signal of your voice for output to the sound field speaker system.

page mute/pass through

The Page Mute feature allows you to connect the TeachLogic amplifier to the school paging/intercom system for muting purposes. A simple connection between the in-classroom paging speaker (typically 25v, 70v or 100v) and the TeachLogic page input will mute all the inputs and pass the page to the speakers connected to the TeachLogic amplifier. System resumes audio (slowly ramping up volume) 6 seconds after no additional page signal is detected.

KEY SPECS (based on 25 V paging systems)

• Page signal required to activate mute function: 6.0 V
- The impedance of the IMA-120 is 160 Kohms in the 25V switch position, and 180 Kohms in the 75 and 100V switch positions.
- Power draw = 0.004 Watts or less (power = voltage*voltage/impedance, or 25*25/160,000).

security alert features

SYSTEM BEHAVIOR

When the Sapphire's "Priority" button is pushed/held for 5 seconds, it sends a signal to the ceiling sensor which passes through the amp to the security alert inter face (an electric relay). The relay contacts opens or close (depending on the normal status) to pass the signal through the paging system as if the paging system's wall-mounted button was being pressed. The amplifier functions normally during the alert, e.g. there is no change to audio input/output volume change nor does the system produce any sound

KEY SPECS

• Contact closure, normally open or closed.
• Field programable for 1-pulse and 4-pulse systems
• Amplifier power LED blinks green when the alert is received
• Functions on primary teacher microphone (Channel A) in each room.

CONNECTION

Uses wire from paging manufacturer's wall-mounted call button panel to connect to amplifier via 3-pin Phoenix connector: COM | NORMALLY OPEN | NORMALLY CLOSED.

system operation

Now that the system is installed and connected, we are ready to plug it in and test its performance. The testing will be done using an IR transmitter (Sapphire or Handheld) to confirm good connectivity and quality audio.

system operation

It is best to have a second person help you set the gain levels for the audio sources as the teacher does not need to hear his/her own voice or audio for it to be working properly.

1. Plug in the Matrix. Note that the power is always on.
2. Confirm power to sensor by verifying the Green LED on edge of sensor is illuminated.
3. Set volume of Ch A volume control to mid scale (12 o'clock).
4. Set volume control on side of Sapphire transmitter to "Normal" level.
5. Switch on by pressing and holding "TL" button until it lights up.
6. Observe that the "TL" LED is solid blue, which indicates it is transmitting.
7. Have another person sit/stand under or in front of a speaker.
8. Slowly adjust "Ch A" volume on Matrix while talking into microphone.
9. Adjust to desired listening level.

CAUTION: Beware of feedback. If feedback occurs, dial down gain control until it goes away.

1. Walk around the room while talking into microphone to confirm good connectivity.
2. Test the mute function by briefly pressing the Sapphire "TL" power button once (flashing blue).
3. Briefly press power button again. The light should return to solid blue.
4. Upon completion of performance test, the installation is complete.
