The OMNITRONIC EM-312 is a slim, rack-mountable microphone/line mixer designed for permanent installation in commercial settings. It is a 12-channel mixer combining 6 mono and 6 stereo inputs.
High Channel Count in 1U: A 12-channel mixer packed into a minimal 1 unit (1U) of rack space (48.3 cm / 19" installation), saving crucial space.
Versatile Inputs:
6 Mono Mic/Line Inputs: Uses combo jacks (XLR/6.3 mm) for connecting microphones or line sources.
3 Stereo Line Inputs: Uses RCA jacks (offering 6 line inputs total).
Switchable Phantom Power: Phantom power can be independently switched on for each microphone input.
Adjustable Priority Circuit: Features an adjustable priority (ducking) function specifically for microphone channel 1, which automatically lowers the volume of other signals when an announcement is made.
Comprehensive Outputs: Includes balanced stereo XLR outputs, unbalanced stereo RCA outputs (for recording), an adjustable mono line output (6.3 mm jack), and a separate 6.3 mm monitoring output for the mic section.
Control and EQ: Features a 3-band equalizer, separate level controls and signal LEDs for all input channels, and a master volume control.
Redundant Power: Includes an additional set of screw terminals for a 24 V DC power input, providing a fail-safe or alternative power option.
