The IRF-2150 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, 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-15 Plug-In Wall Charger for charging the Sapphire transmitters.

The IRF-2150 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.

The IRF-3150 Forum Wireless Microphone System from TeachLogic is a sound-field system for classroom presentation. This system consists of an IMA-320 Amplifier/Receiver Base Station, IRT-55 Sapphire Microphone Transmitters with lithium-ion batteries, an ICS-55 Ceiling Sensor for IR connectivity throughout the room, and four SP-628L Lay-In Ceiling-Mount Speakers. It also includes a BRC-15 Plug-In Wall Charger for charging the Sapphire transmitters.

Each lightweight Sapphire Infrared Microphone Transmitter comes with a rechargeable lithium-ion battery. It can be worn with a lanyard or clipped directly to your neckline collar. It transmits the vocal signal via infrared light to the ICS-55 Dome Sensor installed on the ceiling.

The ideal location for the dome sensor would be in the center of the ceiling. This will provide a clear signal path for the IR transmission from the transmitter without obstruction. In addition, you will have 360° coverage and minimize the transmission distance for more reliable performance. The sensor collects the infrared transmission signal via 6 large detecting diodes.

The signal is then sent via the included 50' plenum-rated cable terminated with RCA connectors to the receiver input of the IMA-320 Forum Amplifier/Receiver Base Station where it is detected and then processed through the power amplifier to up to four SP-628L Lay-In Ceiling Speakers (included). The receiver/amplifier supplies the power to the sensor.

The receiver base station's two wireless microphone channels provide freedom of movement and permit hands-free performance. Its two auxiliary line inputs provide multimedia integration via computers or DVD/iPod units. The base station also has separate outputs for both assistive listening and recording with active boards.

It also includes a BRC-55 Drop-In Battery Charger for charging the Sapphire microphone/transmitter. The system can be added to an existing multi-media system for expanding its utilization to provide voice reinforcement.

The Spectrum III Amplifier/Receiver Base Station features dual IR receivers, four 100W Class D amplifiers, digital equalization, and digital limiting, providing freedom of movement and allowing simultaneous use of two microphones (one Sapphire microphone/transmitter included). When combined with the Sapphire transmitter, the Spectrum III base station delivers several key features such as Security Alert circuit, Teacher Voice Priority, and Remote volume control for line inputs. The four auxiliary inputs provide multi-media integration with even distribution of sound for all audio in the classroom.

The ICS-55 Dome Sensor collects the IR wireless signal from the microphone/transmitter via 6 large detecting diodes and sends a composite signal to the receiver the IMA-820 Spectrum III Amplifier/Receiver Base Station via the included 50' plenum-rated cable. The ideal location for the sensor would be in the center of the ceiling, providing a clear signal path for the IR transmission from the transmitter without obstruction.

The receiver transforms this composite signal into an analog audio signal which is fed to the multimedia amplifier. The amplifier powers the four SP-2000 Wall-/Shelf-Mount Speakers (included) for even voice reinforcement throughout the room. Each of the SP-2000 Full-Range 2-Way Compact Wall-/Shelf-Mount Speaker provides low distortion and a smooth natural frequency response. Each of the speakers can be secured against a wall or other flat surface with the included wall-mount bracket.

The IRF-3655 Forum Wireless Microphone System from TeachLogic is a sound-field system for classroom presentation. This system consists of an IMA-320 Amplifier/Receiver Base Station, two IRT-55 Sapphire Microphone Transmitters with lithium-ion batteries, an ICS-55 Ceiling Sensor for IR connectivity throughout the room, and four SP-628 Ceiling-Mount Speakers. It also includes a BRC-55 3-Port Drop-In Charger for charging the Sapphire transmitters.

Each lightweight Sapphire Infrared Microphone Transmitter comes with a rechargeable lithium-ion battery. It can be worn with a lanyard or clipped directly to your neckline collar. It transmits the vocal signal via infrared light to the ICS-55 Dome Sensor installed on the ceiling.

The ideal location for the dome sensor would be in the center of the ceiling. This will provide a clear signal path for the IR transmission from the transmitter without obstruction. In addition, you will have 360° coverage and minimize the transmission distance for more reliable performance. The sensor collects the infrared transmission signal via 6 large detecting diodes.

The signal is then sent via the included 50' plenum-rated cable terminated with RCA connectors to the receiver input of the IMA-320 Forum Amplifier/Receiver Base Station where it is detected and then processed through the power amplifier to up to four SP-628 Ceiling Speakers (included). The receiver/amplifier supplies the power to the sensor.

The receiver base station's two wireless microphone channels provide freedom of movement and permit hands-free performance. Its two auxiliary line inputs provide multimedia integration via computers or DVD/iPod units. The base station also has separate outputs for both assistive listening and recording with active boards.
