12 Channel Line Mixer with Priority

The Rack Mix 12 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 ¼-inch (6.3mm) mono output that can be used to connect the Rack Mix 12 to a remote mixer, a pair of RCA stereo outputs to connect to a remote recording device, and ¼-inch (6.3mm) mic monitoring port that can be used to monitor the mics’ signals. The Rack Mix 12 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 is 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 variey of applications; everything from a classtroom to a tour bus.
