3. Opsætning og installation
3.1 Power Requirements
The MX418/C is a condenser microphone and requires fantomkraft to operate. Ensure your mixer or audio interface provides 11–52 V DC phantom power. Refer to your audio equipment's manual for details on enabling phantom power.
3.2 Monteringsmuligheder
The microphone comes with both a shock mount and a flange mount for flexible installation.
3.2.1 Flange Mount Installation
The locking flange mount is designed for permanently securing the microphone to surfaces such as lecterns, pulpits, or conference tables.
- Drill an appropriate-sized hole in the desired mounting surface.
- Insert the flange mount into the hole and secure it using the provided hardware.
- Thread the microphone's XLR preamp base into the flange mount until secure.
3.2.2 Shock Mount Installation
The shock mount provides isolation from surface vibration noise, ideal for reducing handling noise or vibrations from the mounting surface.
- Attach the shock mount to a standard microphone stand or other compatible mounting hardware.
- Insert the microphone's XLR preamp base into the shock mount.
3.3 Tilslutning af mikrofonen
- Connect a standard XLR cable (not included) to the XLR preamp at the base of the microphone.
- Connect the other end of the XLR cable to an input on your mixer or audio interface.
- Activate phantom power on the connected input channel.

4. Betjening
4.1 Gooseneck Adjustment
The flexible gooseneck allows for precise positioning of the microphone capsule. Adjust the gooseneck to ensure the microphone is optimally angled towards the sound source, typically 6 to 12 inches (15-30 cm) from the speaker's mouth.
4.2 Cardioid Polar Pattern
The MX418/C features a cardioid polar pattern, which is most sensitive to sound coming from the front and less sensitive to sound from the sides and rear. This helps to reduce pickup of unwanted ambient noise and feedback.

4.3 Windscreen Usage
Attach the snap-fit foam windscreen over the microphone capsule to minimize plosive sounds (like 'p' and 'b' sounds) and breath noise, especially in close-mic situations or environments with air movement.
5. Vedligeholdelse
5.1 Rengøring
To clean the microphone, gently wipe the exterior surfaces with a soft, dry cloth. For the foam windscreen, it can be carefully removed and hand-washed with mild soap and water, then allowed to air dry completely before reattaching.
5.2 Opbevaring
Store the microphone in a clean, dry environment away from extreme temperatures and humidity. When not in use, it is recommended to cover the microphone with a dust cover or return it to its original packaging to protect it from dust and physical damage.
6. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen lydudgang | No phantom power; incorrect cable connection; faulty cable/equipment. | Ensure phantom power is enabled on the mixer/interface. Check all XLR cable connections. Test with a different cable or input. |
| Lav eller forvrænget lyd | Incorrect gain settings; microphone too far from source; phantom power issue. | Adjust input gain on mixer. Position microphone closer to the sound source. Verify phantom power is stable. |
| High-pitched tone or hum | RF interference; ground loop; faulty microphone/preamp. | Ensure cables are not running parallel to power lines. Check for proper grounding. Isolate the microphone to determine if it's the source of the noise. |
| Intermittent clicks or dropouts | Loose connection; cable damage; environmental interference. | Check all cable connections. Replace suspect cables. Ensure no strong electromagnetic fields are nearby. |
| Excessive plosives or breath noise | No windscreen; microphone too close to mouth. | Attach the foam windscreen. Adjust microphone distance from the speaker. |
If issues persist after attempting these solutions, contact Shure customer support or a qualified audio technician.
