TeachLogic IRM-5150 overview

  • 1Description

The IRM-5150 Maxim III Wireless Microphone System with Four Lay-in Panel Speakers from TeachLogic is a sound-field system designed for use in the classroom. The Maxim III features a Digital Feedback Guard (DFG) to eliminate acoustical feedback. It has a 50W Digital Hybrid Class D amplifier. The wireless Sapphire microphone has a capsule which allows maximum gain before feedback. The Maxim III allows for remote adjustment of inputs via the RS-232 wall panel controller. The unit has two infrared wireless microphone receivers which can be used simultaneously. The Maxim III provides four auxiliary line inputs for multi-media integration with even distribution of sound for the audio in the classroom. The RS-232 input is compatible with most wall controllers and allows for remote adjustment of inputs. It has a Line level output for lesson capture and another output for Assistive Listening System (ALS).

The Maxim III comes with the Sapphire IRT-60 microphone transmitter and a rechargeable lithium-ion battery. The Sapphire transmitter can be worn with a lanyard or clipped directly to your neckline collar. It has high level output, reliable connectivity and great definition. With a tap on the power button, the microphone mutes for private conversation-tap again to restore to normal operation. The auxiliary input allows wireless playback of your iPod. A three-position slide switch provides selection of low, medium, or high microphone volume levels.
When combined with the Sapphire IRT-60, the Maxim III delivers several key features such as a Security Alert circuit which is activated by holding down a button for 5 seconds on transmitter, Teacher Voice Priority and Remote volume control for line inputs.

The Maxim III IRM-5150 also includes four lay-in panel speakers, a plug-in battery charger, and a ceiling sensor for IR connectivity.
