The Denon DN-312X 12-Channel Line Mixer is a 12-channel line mixer featuring six mic/line combo inputs, a 3-level EQ and a 1U size. The DN-312X is a 1U rack-mounted 12-channel mixer featuring six mic/line combination inputs each with switchable phantom power and six additional line-level inputs. It has balanced XLR outputs, a 1/4″ (6.3mm) mono output that can be used to connect the DN-312X to a remote mixer, and a pair of RCA stereo outputs to connect to a remote recording device.
Also included is a 1/4″ (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. It has a 3-level equaliser and a controlled priority for Mic/Line 1. It can be powered from a standard AC or a 24V DC power source.
