Frequently Asked Questions - DN312X DENON

How to connect a condenser microphone to the DN312X?

Use a combo input (channels 1-6) with an XLR cable, then set the corresponding switch to PH to activate phantom power (18-21 V). Check that your microphone requires this power.

How does the Mic 1 priority function work?

The Mic 1 Priority knob adjusts the attenuation of other channels when channel 1 receives a signal. At full clockwise (max), no attenuation; at full counterclockwise (min), all other channels are muted.

Can I use an external mixer with the DN312X?

Yes, connect the mono output (6.35 mm) or the recording outputs (RCA) to your mixer's input. Use the master volume to control the level.

How to activate the microphone monitoring output?

Press the Mic On/Off switch (pressed = ON). The signal from mic channels 1-6 is then sent to the Microphone Monitoring output (6.35 mm) and the line outputs are disabled.

What type of cable to use for the line outputs?

For the main line outputs, use balanced XLR cables. For the mono output, a TS 6.35 mm cable. For the recording outputs, stereo RCA cables.

The CLIP LED often lights up. What to do?

Reduce the individual channel levels or the master level (MASTER) to avoid clipping. The CLIP LED should only light occasionally.

How to replace the fuse on the DN312X?

Unplug the device, then use a screwdriver to open the fuse compartment (rear panel). Replace with a fuse of the same rating. Never use a different rating.

Can I power the DN312X with 24 V DC?

Yes, a DC 24 V power input is available. If both AC and DC inputs are connected, AC power takes priority.

How to use the built-in equalizer?

The LOW, MID, and HIGH knobs affect the master mix. Turn them clockwise to boost, counterclockwise to cut frequencies.

What accessories are included with the DN312X?

The box contains: the DN312X mixer, a power cord, a user guide, and a safety and warranty instructions document.

User Guide (English)

Introduction

The DN-312X is an ultra-slim 1U rack-mounted 12-channel mixer with 6 mic/line combination inputs and 6 additional line inputs. It has balanced XLR outputs, a 1/4" (6.35 mm) mono output that can be used to connect the DN-312X to a remote mixer, a pair of RCA stereo outputs that can be used to connect to a remote recording device, and 1/4" (6.35 mm) mic monitoring port that can be used to monitor the mics' signals. The DN-312X provides individual volume control for all inputs in addition to volume control for the mono output port and a master volume control. It has a 3-level equalizer and a controlled priority for Mic/Line 1. It can be powered from standard AC or 24 V DC power source.

Please see this guide's Setup chapter to learn how to integrate DN-312X with your audio system.

1. Power Switch: Use this switch to power DN-312X on or off.
2. Power Light: This light illuminates when DN-312X is powered on.
3. Mic In Level: Turn these knobs to set the input level of the corresponding mic/line inputs (Channels 1–6).
4. Stereo In Level: Turn these knobs to set the input level of the corresponding line inputs (Channels 7/8–11/12).
5. Signal (Sig) Lights: Indicates that the channel's incoming audio signal is within an optimal range.
6. Mic Level: Turn this knob to set the input level of the Mic Monitor output. Use the Mic On/Off button to enable to disable it.
7. Mic On/Off: Press this to turn enable or disable the Mic Monitor output. When the button is depressed (in the down position), the signal from the mic/line inputs (Channels 1–6) will be sent to the Mic Monitor output, and the Line Outs will be disabled. When the button is raised (in the up position), the Mic Monitor output will be disabled, and all channels will be sent to the Line Outs.
8. EQ: Turn these knobs to increase ("boost") or reduce ("cut") the amount of bass frequencies (Low), mid-range frequencies (Mid), and treble frequencies (High) of the main mix.
9. Mono Level: Turn this knob to adjust the level of the Mono Out.
10. Master Level: Turn this knob to adjust the level of the Line Outs, Mono Out, and Rec Out.
11. Level Meters: These lights indicate the audio level of the Line Outs, Mono Out, and Rec Out. The Clip light can light up occasionally, but if it happens too often, reduce the volume of the mix and/or individual channels.

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.

1. 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.

2. Line Inputs (Channels 7/8–11/12): Connect line-level devices to these inputs with standard stereo RCA cables.

3. 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.

4. 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.

5. 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.

6. 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.

Setup

Items not listed under Introduction > Box Contents are sold separately.

To set up DN-312X with your sound system:

1. If you are using any audio source with RCA outputs (Blu-ray ^® players, stereos, etc.), use standard RCA cables to connect them to the line inputs on the rear panel. Your audio sources must be line-level (no phono-level turntables).
2. If you are using microphones or other audio sources that send a line-level signal, connect them to the mic/line inputs on the rear panel.
3. Use standard XLR or 1/4" (6.35 mm) TRS cables to connect the line outputs on the rear panel to your loudspeakers, remote mixer, etc.
4. If you want to send the main mix to a remote recording device, remote mixer, etc., use a standard 1/4" (6.35 mm) TS cable to connect the Mono Out on the rear panel to it. Alternatively, use standard stereo RCA cables to connect the Rec Outs on the rear panel to it.
5. Use the included power cable to connect DN-312X to a power outlet.
6. Power on all of your audio sources (Blu-ray players, stereos, microphones, etc.).
7. Power on DN-312X.
