5. Operating the Microphone
The MXL Revelation FET Mini is designed for straightforward operation, offering flexibility for various recording scenarios.
5.1. Pad Switch
The microphone features a 3-stage attenuation pad located on its body. This switch allows you to reduce the input signal level by -10dB or -20dB, preventing distortion when recording very loud sound sources.
- 0dB: Standard setting for most recording situations.
- -10dB: Use for moderately loud sources, such as close-miked guitar amplifiers or certain vocalists.
- -20dB: Engage for extremely loud sources, like kick drums, brass instruments, or very loud guitar cabinets.

5.2. Phantom Power
Ensure your audio interface or mixer is supplying 48V phantom power to the microphone. Without it, the microphone will not function.
5.3. Placement and Application
The Revelation FET Mini's cardioid polar pattern is effective at capturing sound from the front while rejecting sound from the sides and rear. Experiment with microphone placement to achieve the desired tonal characteristics for your specific source.
- Vocals: Position 6-12 inches from the vocalist, using a pop filter to prevent plosives.
- Acoustic Guitar: Aim towards the 12th fret or soundhole, adjusting distance for desired warmth and clarity.
- Drums: Can be used as a kick drum mic (with pad engaged) or for overheads, depending on desired sound.
- Guitar Amplifiers: Place a few inches from the speaker cone, adjusting for tone. Use the pad for high volume levels.

6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your microphone:
- Cleaning: Use a soft, dry cloth to wipe the microphone body. Avoid using liquid cleaners or solvents, as they can damage the finish or internal components.
- Storage: Always store the microphone in its included carrying case when not in use. This protects it from dust, moisture, and physical damage.
- Handling: Handle the microphone with care. Avoid dropping it or exposing it to extreme temperatures or humidity.
7. Troubleshooting
If you encounter issues with your MXL Revelation FET Mini Microphone, consider the following common troubleshooting steps:
- No Sound:
- Ensure 48V phantom power is activated on your audio interface or mixer.
- Check all XLR cable connections for proper seating.
- Test with a different XLR cable to rule out cable failure.
- Verify input gain levels on your preamp/interface are set appropriately.
- Distorted Sound:
- If recording a loud source, engage the -10dB or -20dB pad switch on the microphone.
- Reduce the input gain on your preamplifier or audio interface.
- Ensure the microphone is not positioned too close to the sound source.
- Excessive Noise/Hum:
- Ensure all cables are properly shielded and not running parallel to power cables.
- Check for ground loops in your audio setup.
- Verify the microphone is securely mounted in the shock mount to minimize mechanical noise.
