When it comes to audio for classrooms, the 15 watt per channel NuVo WA30 stereo amplifier is the right answer. The WA30 is built into a single Decora-type wall plate for easy use, quick installation, and affordability. An integrated volume control keeps the package compact, and two front-mounted stereo 3.5 mm input jacks are offered for local source input. For fixed source installations, rear-mounted screw down terminals are built-in. Power supply included. Power supply and speaker connections are rear-mounted for a tamper-proof connection.
