The DN-312X is a 1U rack-mounted 12-channel mixer that can solve countless audio challenges. It features 6 mic/line combination inputs (HDHQ™ Denon-Marantz proprietary mic pre’s) each with switchable phantom power and 6 additional line-level inputs. It has balanced XLR outputs, a 1/4-inch (6.3mm) mono output that can be used to connect the DN-312X to a remote mixer, a pair of RCA stereo outputs to connect to a remote recording device, and 1/4-inch (6.3mm) mic monitoring port that can be used to monitor the mics’ signals. The DN-312X provides individual level control for all inputs in addition to level control for the mono output port and a master level control. Rounding off the feature set, It has a 3-level equalizer and a controlled priority for Mic/Line 1. It can be powered from standard AC or a 24V DC power source, inviting it to be used in a variety of applications; everything from a classroom to a tour bus.
