1. AC Power Input: Use the included power cable to connect this input to a power outlet.
Alternatively, use the DC power input, described below. (If both power inputs are
connected to power outlets, DN-312X will draw its power from the AC power input.)
2. Fuse Cover: If the fuse is broken, use a screwdriver or other tool to lift this tab, and
replace the fuse with a fuse with the same rating. Using a fuse with an incorrect rating can
damage the unit and/or fuse.
3. DC Power Input: Use a separate DC power supply to connect this input to a power outlet.
Alternatively, use the AC power input, described above. (If both power inputs are
connected to power outlets, DN-312X will draw its power from the AC power input.)
4. Mic/Line Inputs (Channels 1–6): Connect microphones or line-level devices to these
inputs with XLR or 1/4" (6.35 mm) cables.
5. Input Selector (Channels 1–6): Use these switches to set what type of audio source is
connected to each mic/line input: a microphone without phantom power (Mic), a
microphone with +18–21V of phantom power (Ph), or a line-level device (Line).
Note: Most dynamic microphones do not require phantom power, while most condenser
microphones do. Consult your microphone's documentation to find out whether it needs
phantom power.
6. Mic 1 Priority: Turn this knob to set how loud the volume level of all other inputs will be
when the Channel 1 mic/line input receives an incoming signal. At its lowest setting, a
signal received by the Channel 1 mic/line input will mute all other input signals entirely. At
its highest setting, a signal received by the Channel 1 mic/line input will not affect the other
input signals at all.
7. Line Inputs (Channels 7/8–11/12): Connect line-level devices to these inputs with
standard stereo RCA cables.
8. Line Out: Use standard XLR cables to connect these outputs to your loudspeakers or
amplifier system. Use the Master Level knob to control the level of these outputs.
9. Mono Out: Use a standard 1/4" (6.35 mm) TS cable to connect this output to a remote
recording device, remote mixer, etc. The signal sent from this output is a summed mono
signal of the line outs.
10. Mic Monitor: Use a standard 1/4" (6.35 mm) cable to connect this output to a powered
monitor, remote mixer, etc. When the Mic On/Off button is depressed (in the down
position), the signal from the mic/line inputs (Channels 1–6) will be sent to this output, and
the Line Outs will be disabled. When the Mic On/Off button is raised (in the up position),
this output will be disabled, and all channels will be sent to the Line Outs.
11. Rec Out: Use standard stereo RCA cables to connect these outputs to a remote recording
device, remote mixer, etc. Use the Master Level knob to control the level of these outputs.
