4. Operating Instructions

4.1 Powering On/Off

The Proel DM220 features an integrated on/off switch for convenient control. To activate the microphone, slide the switch to the 'ON' position. To deactivate, slide it to the 'OFF' position. Always ensure the microphone is off when not in use to prevent accidental sound capture or feedback.

4.2 Microphone Placement

Due to its cardioid polar pattern, the DM220 is most sensitive to sounds directly in front of it and rejects sounds from the sides and rear. For optimal vocal performance, position the microphone directly in front of the sound source (e.g., singer's mouth) at a distance of 2-6 inches (5-15 cm). Experiment with distance to achieve the desired tone and to minimize plosive sounds (P, B sounds).

5. Maintenance

5.1 Cleaning

• Wipe the microphone body with a soft, dry cloth.
• For the grille, use a slightly damp cloth to remove any residue, then dry thoroughly. Do not allow moisture to enter the microphone capsule.
• Avoid using harsh chemicals, solvents, or abrasive cleaners.

5.2 Storage

When not in use, store the microphone in its protective carrying pouch in a cool, dry place, away from direct sunlight and extreme temperatures. This helps protect the microphone from dust, moisture, and physical damage.

6. Troubleshooting

• No Sound Output:
  • Ensure the microphone's on/off switch is in the 'ON' position.
  • Check all XLR cable connections at both the microphone and the audio input device.
  • Verify that the input channel on your mixer or interface is selected and its gain/volume is turned up.
  • Test with a different XLR cable to rule out cable failure.
  • Test the microphone on a different input channel or device if possible.
• Low or Distorted Sound:
  • Adjust the gain level on your mixer or audio interface. Too low gain results in weak sound, too high can cause distortion.
  • Ensure the microphone is positioned correctly relative to the sound source.
  • Check for any obstructions on the microphone grille.
• Feedback (High-pitched squealing):
  • Reposition the microphone further away from speakers or monitors.
  • Reduce the overall volume or the gain of the microphone channel.
  • Ensure speakers are not pointing directly at the microphone.
