TeachLogic IRM-5650 Maxim III Wireless Classroom Microphone System with Sapphire Mic & 4 Lay-in Speakers

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.

TeachLogic IRT-60 overview

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.

TeachLogic BRC-60 overview

The BRC-60 Drop-in Charger from TeachLogic is used to power up one IRH-35 handheld transmitter and up to two IRT-55/60 Sapphire transmitters. The BRC-60 can also be powered directly from the USB port on Maxim III and Spectrum III amplifiers.

The addition of a set of magnets on the bottom of the charger allows rock solid attachment to a WM-400 wall Cabinet (sold separately). Using this wall cabinet allows you to free up valuable space for other classroom items and makes for a very clean install by hiding all the cables. The magnets can be replaced with included rubber feet.
