a brief word about infrared 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”.
Forum owner’s manual product description The Forum is an infrared wireless microphone sound system. It is the nucleus of the classroom sound field system which provides optimum voice reinforcement. The addition of a Forum sound field system will transform your classroom into a totally hands free, voice re-enforcement system, resulting in reduced voice fatigue, enhanced student listening and improved student learning.
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 (IMA320). The receiver/amplifier processes the signal and produces an analog signal of your voice for output to the sound field speaker system.
Forum owner’s manual infrared microphone/transmitters The infrared microphone/transmitter is comprised of a microphone input, signal processing circuits and several emitting diodes that transmit the vocal signal to the sensor. The microphone/transmitter can be the Sapphire or Handheld. The rechargeable batteries will provide 6–8 hours of service per charge. Place the microphone/transmitter in the charger for overnight charge and it will be ready for another day’s use.
features • Condenser microphone element • Power “on/off ” switch • Battery level indicator— LED • Channel “A” or “B” selectable • 10 high-power emitting diodes • Diodes at top and bottom of handle for increased Coverage (2 Top aimed out, 6 Bottom 360°, 2 Bottom aimed down) • 360º IR radiation for assured connectivity • Two “AA”, Duracell, rechargeable NiMH batteries IRH-35 handheld transmitter The Handheld Microphone Transmitter (IRH35) is most applicable for student use or direct presentation.
Forum owner’s manual BRC-55 drop-in battery charger This stylish desktop drop-in charging station makes it convenient and easy to recharge both Sapphire Pendant and Handheld Microphones. Charge one IRH-35 handheld transmitter and up to two IRT-60 Sapphire transmitters simultaneously. Charging indicator lights illuminate Red when charging, and Green when fully charged. The “TL” logo illuminates Blue when plugged in.
installation of ICS-55 ceiling sensor The ideal location for the ceiling sensor is in the center of the ceiling. This will provide a clear signal path for the IR transmission from the transmitter to the dome sensor without obstruction. In addition, you will have 360º coverage and will minimize the transmission distance for more reliable performance. An additional sensor can be added for large or odd shaped rooms.
Forum owner’s manual installation of speakers Two wall mount or ceiling speakers can be powered by the receiver/amplifier. It has two amplifiers (25 watts ea.). One speaker will be connected to each amplifier. Optional: Two additional speakers can be powered by the amplifier. Connect two speakers in parallel. Then bring a cable from each pair to the amplifier. Connect one pair to each amplifier. installing two SP-628 ceiling speakers • Determine the listening area.

Forum owner’s manual operation of wireless microphone Now that the system is installed and connected, we are ready to turn the system “ON” and test its performance. The testing will be done using an IR transmitter (Sapphire or Handheld) to confirm good connectivity and quality audio.
troubleshooting Problem System is turned “on” but there is no sound System has power but no sound Voice is distorted and/or signal dropout occurs Solution • Verify AC power; the Blue LED lights when turned “on” • Check if system has been unplugged • Check circuit breaker • Call maintenance for assistance • Turn “on” microphone/ transmitter • Check for IR transmission, Signal presence (Orange LED) • Check the Green LED in the sensor • If sensor LED is not lit • Sensor has been disconnected • Power
