Forum system
The Forum system is comprised of a microphone / transmitter, either the
Sapphire (IRT-55), and/or Handheld (IRH-35) for voice transmission to a
ceiling sensor (ICS-55) that sends the signal to the receiver / amplifier (IMA-
320). The receiver/amplifier processes the signal and produces an analog
signal of your voice for output to the sound field speaker system.
