Setup
- Unpack Components: Carefully remove the microphone, XLR cable, and pole clamp from the hard carrying case.
- Attach Pole Clamp: Secure the eXtreme MS Series Pole Clamp to a standard microphone stand. Ensure it is tightened sufficiently to hold the microphone securely.
- Insert Microphone: Gently insert the base of the DM58 microphone into the pole clamp. The clamp should hold the microphone firmly without excessive force.
- Connect XLR Cable: Connect the male end of the provided XLR cable to the XLR port at the base of the microphone. Connect the female end of the XLR cable to the microphone input of your audio mixer, amplifier, or karaoke machine. Ensure both connections are secure.
- Power On (if applicable): If your audio device requires it, ensure phantom power is turned off for dynamic microphones. The DM58 does not require phantom power.
Operation
The Extreme DM58 microphone is designed for straightforward operation. Follow these guidelines for optimal performance:

- Power Switch: Locate the ON/OFF switch on the microphone 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 preserve connected equipment.
- Microphone Placement: For singing and voice applications, hold the microphone approximately 2-6 inches (5-15 cm) from your mouth. Experiment with distance to achieve the desired vocal presence and avoid plosive sounds.
- Polar Pattern: The DM58 features a unidirectional (cardioid) polar pattern, meaning it is most sensitive to sound coming from the front and rejects sound from the sides and rear. This helps to minimize feedback and isolate the desired sound source.
- Volume Control: Adjust the input volume on your mixer or amplifier to a suitable level. Start with a low volume and gradually increase it to avoid clipping or distortion.
Maintenance
Proper care will extend the life and performance of your Extreme DM58 microphone:
- Cleaning: Use a soft, dry cloth to wipe down the microphone body and grill after each use. For stubborn grime on the metal parts, a slightly damp cloth can be used, but ensure no moisture enters the microphone capsule. Do not use harsh chemicals or abrasive cleaners.
- Storage: Always store the microphone, cable, and clamp in the provided hard carrying case when not in use. This protects the components from dust, moisture, and physical damage.
- Cable Care: Avoid kinking or sharply bending the XLR cable. Coil it loosely when storing to prevent internal wire damage.
- Avoid Drops: While durable, dropping the microphone can damage the internal components or the grill. Handle with care.
Troubleshooting
If you encounter issues with your Extreme DM58 microphone, try the following solutions:
- No Sound Output:
- Ensure the microphone's ON/OFF switch is in the "ON" position.
- Check that the XLR cable is securely connected to both the microphone and your audio device (mixer, amplifier, etc.).
- Verify that the input volume on your audio device is turned up.
- Test the microphone with a different XLR cable if available, to rule out a faulty cable.
- Test the microphone with a different audio input on your device, or a different audio device entirely, to isolate the problem.
- Distorted Sound:
- Reduce the input volume on your audio device.
- Ensure you are not speaking or singing too close to the microphone, which can cause clipping.
- Feedback (High-pitched squealing):
- Move the microphone further away from speakers.
- Point the microphone away from speakers.
- Reduce the overall volume or specific frequency ranges on your audio device.
