The DN312X from Denon is a 1U rack-mounted 12-channel mixer with microphone priority, well suited for live performances, karaoke, bars, clubs, studios, and more. The mixer features 6 combo XLR-1/4" inputs that are switchable between Mic, Line and Phantom Power (PH), which allows for compatibility with condenser microphones. Channel-1 offers a variable mic priority knob, which at its lowest setting will mute all other microphone channel inputs entirely when a signal is present on Mic 1. The highest setting has no effect at all, while any setting in between works well for ducking music when making announcements.
