User manual for the TeachLogic IRF-2655 Forum 232 Wireless Classroom IRF-2655/CS4
The user manual for the TeachLogic IRF-2655 Forum 232 Wireless Classroom IRF-2655/CS4 provides
necessary instructions for the proper use of the product A/V Presentation - Assistive Listening - Assistive Listening Systems.
The IRF-2655 Forum 232 Wireless Microphone System from TeachLogic is a sound-field system for classroom presentation. This system consists of an IMA-232 Amplifier/Receiver Base Station, two IRT-60 Sapphire Microphone Transmitters with Lithium-ion Batteries, an ICS-55 Ceiling Sensor for IR connectivity throughout the room, and four CS-4 Ceiling Speakers. It also includes a BRC-55 Drop-In Charger for charging the Sapphire transmitters.
The IRF-2655 features a Digital Feedback Guard (DFG) that eliminates 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 system allows remote adjustment of inputs via the RS-232 wall panel controller. The unit has two infrared wireless microphones which can be used simultaneously. It 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 is an infrared wireless microphone sound system. It is the nucleus of the classroom sound field system which provides optimum voice reinforcement. The wireless function permits 360° connectivity throughout the classroom regardless of body position or orientation.
The system is comprised of an infrared detecting sensor installed in the ceiling. The sensor collects the IR wireless signal from the microphone/transmitter and sends a composite signal to the mixer/amplifier via the included 50' plenum-rated cable. The receiver transforms the composite signal into an analog audio signal which is fed to the amplifier mixer. Two other audio sources, such as computer, DVD, VCR, or projector can be plugged in to the Forum 232. The volume level of each input will be controlled by the individual volume control of each input. The audio will then be fed to the speakers in the room for even voice reinforcement throughout the room.
On the front panel of the Forum 232, there are two 3.5mm output jacks for interface with an assistive listening system (ALS) and lesson capture (REC). The rechargeable batteries offer 6 to 8 hours of usage per charge. The drop-in charger will recharge the batteries overnight, ready for another day's use.
