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.
10.
Walk around the room while talking into microphone to confirm good connectivity.
11.
Test the mute function by briefly pressing the Sapphire “TL” power button once (flashing
blue).
12.
Briefly press power button again. The light should return to solid blue.
13.
Upon completion of performance test, the installation is complete.
CHANGING MICROPHONE CHANNELS
If you’re using 2 Sapphire microphones in a single room, you’ll need to change one to channel “B” (All
Sapphire mics are shipped in channel A). Handheld microphones are always shipped in channel “B”
setting.
Sapphire: There is an “A–B” switch in the battery compartment. Remove battery cover on back, lift up
battery and locate the switch. Make the change.
Handheld: Unscrew barrel and remove. Note “A–B” switch on side of battery holder. Make the
change.

testing will be done using an IR transmitter (Sapphire or Handheld) to confirm good connectivity and
quality audio.
