The Dynacord U120:1M is a 120W mixer amplifier with four inputs and a single output that drives 4 ohm, 8 ohm, 70V or 100V loudspeaker lines. It combines mic and music sources with VOX ducking, a chime and an EMG override, for background music and announcements in bars, restaurants, shops, schools, houses of worship and meeting rooms. The 1U half-rack chassis fits two units side by side in one rack space.
