Matrix system
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.
