Forum 232 system
The Forum 232 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-232).
The receiver/amplifier processes the signal and produces an analog signal of
your voice for output to the sound field speaker system.
