Denon DN-280 60W Mono Zone Amplifier with Microphone Input (70V/100V/4 Ohms)
EAN: 694318024584
The Denon DN-280 is a compact zone amplifier with a built-in XLR input that lets you plug a microphone. A 3.5mm aux input on the front panel and a dual-RCA channel input on the rear panel accept stereo audio signals from external playback devices such as a smartphone or a stereo tuner. The stereo signals and the mic are all summed into mono for paging, P.A. announcements, and background-music applications.
