The IRV-3415/CS4 VoiceLink Plus Infrared Wireless Classroom Microphone System from TeachLogic is a sound-field system for classroom presentation. This system consists of an IMA-100 Amplifier/Receiver Base Station, one IRT-55 Sapphire Microphone Transmitter with lithium-ion batteries, an ICS-55 Ceiling Sensor with 50' plenum rated cable for IR connectivity throughout the room, and four SP-628 Ceiling-Mount Speakers. It also includes a BRC-15 Plug-In Charger for charging the Sapphire transmitter.
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 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-100 VoiceLink Plus 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 auxiliary line input provides multimedia integration via computers or DVD/iPod units.
IMA-100 Voicelink Plus 1-Channel Infrared Microphone Receiver/Amplifier with Power Supply
The IMA-100 Voicelink Plus 1-Channel Infrared Microphone Receiver/Amplifier with Power Supply from TeachLogic features a 1-channel infrared receiver and two 10W amplifiers to power two or four speakers (sold separately). This receiver/amplifier is a part of the Voicelink Plus Wireless Classroom Microphone System, which also consists of a microphone/transmitter and ceiling sensor.
The ceiling sensor (sold separately) senses the infrared signal emitted from the microphone/transmitter (sold separately) and sends the voice signal to the receiver. The receiver processes the signal and produces an analog signal which is fed to the power amplifier. The output of the amplifier is fed to the speakers. The receiver can also accept an input from another audio source such as an iPod, computer, DVD, or video projector via the auxiliary input on the front panel.
The receiver/amplifier can be placed on desk top, mounted on the wall, or on top or under a shelf using the mounting flanges and hardware provided.

Two 10W amplifiers
One 4-pin Phoenix speaker out connector
One line level auxiliary input on the front panel with adjustable gain, 3.5mm input jack

Infrared Dome Sensor
TeachLogic's Infrared Dome Sensor needs to be installed on the ceiling at least 3' from the video projector. It comes with a mounting/support bracket and 50' of plenum rated cable with RCA connector on each end. 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 to the dome sensor without obstruction. In addition, you will have 360° coverage and will minimize the transmission distance for more reliable performance. It collects the infrared transmission signal via 6 large detecting diodes. The sensor is connected to the mixer/amplifier via a plenum rated cable terminated with RCA connectors. The mixer/amplifier supplies the power to the sensor.
Easily installs on ceiling "T" bar with track bracket
6 large receiving diodes for infrared reception
