Denon DN-280 is a compact, high-power amplifier that sums stereo signals to a mono output for paging, public announcements, and background music applications. The Denon Professional DN-280 is the ideal solution.

With a space-saving half-rack profile, the DN-280 features a paging microphone input, a 3.5 mm (1⁄8-inch) AUX input on the front panel, and stereo analog inputs (summed to MONO) for signals from external playback devices such as an iPhone or stereo tuner.

The amplifier drives a 4Ω load or a 70V / 100V speaker, making it perfect for multi-speaker setups in small retail stores or medical offices. A powerful, cool-running Class D amplifier delivers 100 watts and 95 dB, ensuring extremely clean performance under all conditions.

The DN-280 features built-in short-circuit protection and front-panel LEDs for signal presence, clipping status, and thermal shutdown.
