The 880iR is designed with advanced features that adapt to today's changing classroom environment, and allow for future multimedia expansion. Projectors, electronic white boards, computers, and plasma screens all require a robust solution that will deliver clear, full sound reproduction in addition to the best speech intelligibility for teachers and student. Distributing the audio to every child, regardless of where they are seated, improves the dynamic of interactive classrooms.






The new REDMIKE™ is a pendant-style wireless microphone that can be worn comfortably around the teacher’s neck or used as hand-held for student use.  The 880iR is equipped with two independent channels allowing the use of two microphones simultaneously.  Each system includes a single REDMIKE classroom microphone.




Speaker Choices

LightSPEED offers multiple speaker options to provide optimum sound in every type of classroom.



Technology Integration

Today's classrooms are increasingly rich in new technology—computers, digital projectors, and electronic white boards—and old stand-bys like TVs, VCRs and DVD players. With the addition of technology, audio is the one component that cannot be overlooked. Studies have shown that up to 75% of the school day involves listening activities, confirming that hearing is the primary channel for learning.

It's important to amplify the teacher's voice; it's equally crucial that all students are able to hear the other audio sources used in the classroom.The 880iR is designed with the multimedia classroom in mind, and will amplify the audio of up to four different sources, with volume control for each.
