4. Operation

4.1 Front Panel Controls Overview

The front panel of the Numark M2 provides access to all essential mixing controls, including channel faders, EQ knobs, crossfader, and microphone controls.

4.2 Channel Controls

Each of the two channels features dedicated controls for audio input and equalization.

• GAIN Knob: Adjusts the input level for the respective channel. Set this to achieve a strong signal without clipping (distortion).
• TREBLE, MID, BASS Knobs: These are 3-band EQ controls. Turn clockwise to boost frequencies and counter-clockwise to cut them.
• PHONO/LINE Switch: Selects between phono (turntable) and line (CD player, media player) input sources for the channel.
• Channel Fader: Controls the volume level of the channel's audio output.

4.3 Microphone Input

The M2 includes a dedicated microphone input with its own set of controls.

• MIC GAIN Knob: Adjusts the input level of the connected microphone.
• MIC TREBLE Knob: Adjusts the high frequencies of the microphone signal.
• MIC BASS Knob: Adjusts the low frequencies of the microphone signal.

4.4 Master Output

The master section controls the overall output level and cueing functions.

• MASTER Knob: Controls the overall volume level of the main mix output.
• LED Level Meters: Provide visual feedback of the master output level. Aim for levels that are strong but do not consistently peak into the red.

4.5 Cueing

The cue section allows you to monitor channels through your headphones independently of the master output.

• CUE GAIN Knob: Adjusts the volume level of the headphone output.
• CUE Buttons (CH1/CH2): Press to send the audio from the corresponding channel to your headphones.
• CUE FADER: Blends between the cued channels in your headphones.

4.6 Crossfader Controls

The crossfader allows for smooth transitions between channels.

• Crossfader: Slides horizontally to blend audio between Channel 1 (left) and Channel 2 (right).
• CF SLOPE Switch: Adjusts the curve of the crossfader. A sharper slope is ideal for scratching, while a gentler slope is better for smooth mixing.
• CF MODE (NORMAL/REVERSE) Switch: Reverses the direction of the crossfader. In reverse mode, moving the fader to the left will play Channel 2, and to the right will play Channel 1.

5. Maintenance

5.1 Cleaning

Regular cleaning helps maintain the performance and longevity of your mixer.

• Always disconnect the power adapter before cleaning.
• Use a soft, dry cloth to wipe down the exterior of the mixer.
• For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth. Avoid using harsh chemicals or abrasive cleaners.
• Keep liquids away from the faders and knobs to prevent damage.

5.2 Storage

When not in use, store the mixer in a cool, dry place, away from direct sunlight and extreme temperatures. If transporting, use a protective case to prevent physical damage.

6. Troubleshooting

If you encounter issues with your Numark M2 mixer, consider the following basic troubleshooting steps:

• No Power: Ensure the power adapter is securely connected to both the mixer and a working power outlet. Check the power switch on the rear panel.
• No Sound Output:
  • Verify all audio cables are correctly connected to the appropriate inputs and outputs.
  • Check that the PHONO/LINE switches are set correctly for your input sources.
  • Ensure channel faders and the master volume knob are turned up.
  • Confirm your amplifier or powered speakers are turned on and their volume is adjusted.
• Distorted Sound:
  • Reduce the GAIN knobs for individual channels and the MASTER knob to prevent clipping (indicated by red LEDs on the level meters).
  • Check the input levels from your audio sources.
• Humming/Buzzing Noise: Ensure all ground wires from turntables are properly connected to the mixer's ground terminal. Check for loose cable connections.
• Crossfader Issues: If the crossfader feels stiff or unresponsive, it may require cleaning or replacement. Refer to the maintenance section or contact support.
