Teach Logic IRV-3415/WM4

The Teach Logic IRV-3415/WM4 consists of an infrared wireless microphone receiver, a Sapphire infrared transmitter microphone, 4 wall-mount speakers, and a ceiling sensor. VoiceLink Plus systems are designed to reinforce the teacher's voice and amplify media sources in classrooms. The IMA-100 wireless microphone receiver features a 20W amplifier, which powers the four SP-2000 wall-mount speakers. Teach Logic's IRT-55 Sapphire infrared transmitter/microphone is engineered to transmit the presenter's voice while granting freedom of movement throughout the classroom via the ICS-55 infrared dome sensor receiver. A Lithium battery and a plug-in battery charger for the microphone are provided. Connection to a computer DVD or iPod is facilitated by an auxiliary input on the receiver's front panel.

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 Teach Logic 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.

• 1-channel infrared receiver
• 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
• Two RCA sensor inputs
• Includes mounting brackets

Infrared Dome Sensor

Teach Logic'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
