C2G 8 Ohm 50W Plenum Rated Audio Amplifier with Noise Reduction

The C2G 40880 is an 8 Ohm audio amplifier that supplies a total of 50 Watts, sending 25 Watts to each stereo channel. It is plenum rated, so installers can place it above a drop ceiling or inside other air-handling spaces that must meet building codes. The compact chassis, roughly four and a half inches wide, slips easily behind a display or inside a lectern without crowding other gear.

Hook-ups are simple. A 3.5 millimeter input welcomes laptops and phones, while left and right RCA jacks accommodate media players or in-room computers. Once a source is connected, the built-in noise reduction circuit works quietly in the background to eliminate hum and buzz that often occur when different devices share a power strip. Listeners hear clean, intelligible audio instead of distracting interference.

Energy management happens automatically. After five minutes without a signal, the amplifier enters standby to conserve power, waking the moment audio returns. A 12-volt DC output on the rear panel can run a wall controller or another small device, reducing the number of separate power adapters in the rack or ceiling.

Whether it is reinforcing speech in a classroom, driving background music in a conference room, or powering ceiling speakers in a home office, this amplifier delivers dependable performance in places where space and code compliance both matter. Integrators appreciate FCC and TAA compliance, while end users notice only the clear sound.
