Product Overview
The C2G CG40100 Audio Amplifier — Plenum-Rated is a compact commercial audio amplifier designed for direct installation in plenum air-handling spaces without a separate fire-rated enclosure, providing clear audio amplification for classroom and conference room presentation systems. Verified for plenum installation by laboratory testing, it helps ensure students and meeting attendees can hear instructors and presenters clearly, addressing the common challenge of inadequate audio in rooms with high ceilings or poor acoustics.
Product Description

The CG40100 can be mounted directly above the ceiling in the plenum air space without requiring an additional fire-rated metal enclosure box — reducing installation labor and material cost compared to non-plenum alternatives. Designed for classroom and training environments where voice intelligibility from the instructor microphone or presentation audio system is essential for learning outcomes.
