Application
The 880iR is designed with advanced features that adapt to today's
changing classroom environment, and allow for future multimedia
expansion. Projectors, electronic whiteboards, 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.

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.

Speaker Options
Single Speaker Solutions
Lightspeed's flat-panel speakers produce a very wide dispersion of
sound, resulting in excellent distribution throughout the entire
classroom from a single speaker. Installation is very simple and
speech intelligibility is superb.
Traditional Speaker Solutions
For larger or multimedia classroom applications, we offer a line of
traditional speakers, which places multiple speakers around the
classroom. These speaker solutions cover classrooms up to 1600 square
feet and will deliver a full range of sound.
