  • 1Description

The IRM-5650 Maxim III Wireless Microphone System from TeachLogic is a sound-field system for classroom presentation. This system consists of an IMA-520 Amplifier/Receiver Base Station, IRH-35 Handheld Infrared Transmitter/Microphone with NiMH Batteries, 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 IRM-5650 serves as the optimum sound-field system with 50W of power for large rooms or rooms with high ambient sound levels. It helps create a good intelligible learning environment over a large area with up to 4 ceiling or wall speakers (available separately).

The four auxiliary inputs provide multimedia integration with even distribution of sound for all audio in the classroom. The unit also features RS-232 wall panel control of the line inputs, fire alarm connection (AC or DC), remote teacher security alert, teacher priority with instant attenuation of the line levels via Sapphire IRT-60 pendant mic (available separately), DFG (Digital Feedback Guard), and switchable anti-hum circuit on the computer input.

The Maxim III 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. The audio will then be fed to the speakers in the room for even voice reinforcement throughout the room. It also includes a 100' plenum rated 18 gauge speaker cable. 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.

  • IMA-520 Maxim III 2-Channel Receiver / Amplifier Base Station with Switching Power Supply

  • 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
  • IRT-60 Sapphire Infrared Transmitter/Microphone w/ Security Alert & Rechargeable Battery

    Well suited for classrooms and forums, the rechargeable IRT-60 Sapphire Infrared Transmitter/Microphone from TeachLogic offers the same aesthetic design and feature set as the IRT-55 Sapphire, but with an additional remote "Security Alert", allowing teacher priority with instant attenuation of the line levels to work with the optional Forum 232 and Maxim III amplifiers.

    The Sapphire can be worn with a lanyard or clipped directly to your neckline collar and offers a high level output, reliable connectivity, and great definition. With a built-in breath filter, the Sapphire can function as a pass-around hand microphone. Tapping the power button momentarily mutes the microphone, allowing for private conversations. The 3.5mm auxiliary input allows wireless playback of your iPod, while a three-position slide switch provides selections of low, medium, or high microphone volume levels. The included Lithium-Ion battery offers up to 9 hours use. The Sapphire IRT-60 ships with a BRC-15 wall charger and a breakaway lanyard.
