1. Introduction
This manual provides essential information for the proper setup, operation, and maintenance of your Pronomic DM-58-B Vocal Microphone. The DM-58-B is a dynamic microphone designed for a variety of applications, including vocal performances, public speaking, and recording. Its supercardioid polar pattern helps to minimize feedback, and its robust construction ensures reliability.

3. Setup
- Unpack Components: Carefully remove the microphone, stand adapter, and carrying case from their packaging.
- Attach Stand Adapter: Screw the microphone stand adapter onto a compatible microphone stand.
- Mount Microphone: Gently insert the microphone into the stand adapter. Ensure it is securely held.
- Connect XLR Cable: Connect a standard 3-pin XLR cable (not included) to the XLR output connector at the base of the microphone. Connect the other end of the XLR cable to your audio mixer, amplifier, or audio interface.
- Power On (if applicable): Ensure your connected audio equipment is powered on and configured for microphone input.
4. Operating Instructions
- Power Switch: The DM-58-B features an ON/OFF switch on its body. Slide the switch to the 'ON' position to activate the microphone. Slide it to 'OFF' when not in use to prevent unwanted noise and save power on connected devices if applicable.
- Microphone Placement: For optimal sound quality and to minimize feedback, position the microphone approximately 2-6 inches (5-15 cm) from the sound source. Due to its supercardioid polar pattern, the microphone is most sensitive to sounds directly in front of it and rejects sounds from the sides and rear.
- Gain Adjustment: Adjust the input gain on your mixer or audio interface to achieve a clear signal without clipping (distortion). Start with the gain low and gradually increase it while speaking or singing into the microphone.
- Feedback Control: The supercardioid pattern helps reduce feedback. If feedback occurs, try repositioning the microphone, reducing the monitor volume, or using an equalizer to cut problematic frequencies.
5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the microphone body. For the grille, a soft brush can be used to remove dust or debris. Do not use liquid cleaners directly on the microphone.
- Storage: When not in use, store the microphone in its protective carrying case to shield it from dust, moisture, and physical damage.
- Handling: Avoid dropping the microphone or subjecting it to strong impacts, as this can damage the internal components.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Microphone switch is OFF XLR cable not connected properly Audio equipment input gain too low Faulty XLR cable or audio equipment | Slide switch to ON Ensure cable is fully inserted at both ends Increase input gain on mixer/interface Test with a different cable or equipment |
| Poor sound quality / Distortion | Input gain too high Microphone too close to sound source Damaged microphone capsule | Reduce input gain Increase distance from sound source Contact support for repair/replacement |
| Feedback (howling sound) | Microphone too close to speakers/monitors High gain settings Room acoustics | Reposition microphone away from speakers Reduce input gain or master volume Use an equalizer to cut problematic frequencies |
