The Forum 232 2-Channel Infrared Receiver/Amplifier Base Station with Switching Power Supply from TeachLogic is the nucleus of the Forum 232 Wireless Classroom Microphone System. This receiver is designed for use with the Sapphire or handheld microphone transmitters (all sold separately). These transmitters transmit the vocal signal via infrared light to the dome sensor (sold separately) installed on the ceiling. The signal is then sent via cable to the receiver input of the mixer/amplifier. The signal is detected and then processed through the power amplifier to the speakers.
The unit features RS-232 wall panel control of the line inputs, remote teacher security alert, teacher priority with instant attenuation of the line levels via Sapphire IRT-60 pendant mic (available separately), DFG (Digital Feedback Guard), and switchable anti-hum circuit on the computer input.
