The IRF-2150 Forum 232 Wireless Microphone System with Four Wall Mount Speakers from TeachLogic is a sound-field system designed for teachers in a classroom environment. The IRF-2150 features a Digital Feedback Guard (DFG) to eliminate acoustical feedback. The wireless Sapphire microphone has a capsule which allows maximum gain before feedback. It has a 50W Digital Hybrid Class D amplifier. The Forum 232 allows for remote adjustment of inputs via the RS-232 wall panel controller. The unit has two infrared wireless microphone receivers which can be used simultaneously. The IRF-2150 provides two auxiliary line inputs for multi-media integration with even distribution of sound for the audio in the classroom. The Forum 232 has a Line level output for lesson capture and another output for Assistive Listening System (ALS).
The Forum 232 comes with the Sapphire microphone transmitter and a rechargeable lithium-ion battery. The Sapphire transmitter can be worn with a lanyard or clipped directly to your neckline collar. It has high level output, reliable connectivity and great definition. With a tap on the power button, the microphone mutes for private conversation-tap again to restore to normal operation. The auxiliary input allows wireless playback of your iPod. A three-position slide switch provides selection of low, medium, or high microphone volume levels.
The Forum 232 IRF-2150 includes four two-way wall mount speakers, a ceiling sensor for IR connectivity and a plug-in battery charger.
