Classroom stereo amplifier

The C2G 40573 delivers 45 watt stereo amplification for classrooms and conference rooms. It accepts line-level signals from laptops or DVD players and drives speakers to distribute sound evenly across the space. Integrated Hummbuster technology filters out hum caused by ground loops for cleaner audio.

Plenum-rated enclosure with two analogue inputs

A black metal chassis rated for plenum spaces measures 1.7 by 5.5 by 4.1 inches and weighs 2.75 pounds. One 3.5 mm stereo jack and one RCA L/R pair provide two analogue audio inputs for flexible device connections. A 60 watt power supply and detachable terminal blocks are included for installation.

45 watt RMS output into 4 ohms

The amplifier produces 45 watts RMS per channel into a 4 ohm load across a 20 Hz to 20 kHz frequency response. This power level suits distributed speech and background music in medium-sized rooms. Buyers needing higher output for larger venues or multi-zone paging should consider a different model.
