Opsætning
Tilslutning af mikrofonen
The M 130 connects via a standard XLR cable. Ensure your audio interface or mixer provides a suitable microphone input. This microphone does not require phantom power, as it is a passive ribbon microphone. Connecting it to a phantom power source will not damage the microphone, but it is unnecessary for operation.
Placering af mikrofonen
The M 130 features a figure-eight polar pattern, meaning it picks up sound equally from the front and rear, while rejecting sound from the sides. This characteristic is crucial for effective placement.
- For Stereo Recording: Two M 130 microphones can be arranged in a Blumlein pair (crossed figure-eight patterns) for natural stereo imaging.
- For Instrument Recording: Position the microphone directly facing the sound source for direct sound, or slightly off-axis to capture more room ambience. Its side rejection is useful for isolating instruments in a live room.
- For Ambience: Place the microphone in a room to capture the natural reverberation and spaciousness.

Operating the M 130
Polar Pattern Characteristics
The M 130's figure-eight polar pattern is highly effective for rejecting off-axis sound, particularly from the sides. This makes it an excellent choice for:
- Reducing bleed from other instruments in a multi-microphone setup.
- Capturing the natural acoustics of a room without excessive direct sound.
- Creating detailed stereo recordings when used in pairs.
Optagelsesapplikationer
The M 130 is versatile and can be used for a variety of recording tasks:
- Trommer: Overhead, room, or snare bottom.
- Guitar Amplivsstil: Capturing the full body and tone.
- Vokal: Can provide a warm, vintage tone, especially in well-treated rooms.
- Strings and Brass: Capturing the natural resonance and harmonics.
Pleje og vedligeholdelse
To ensure the longevity and optimal performance of your Beyerdynamic M 130, follow these care guidelines:
- Opbevaring: Always store the microphone in its protective case when not in use to prevent dust accumulation and physical damage.
- Rensning: Brug en blød, tør klud til at tørre mikrofonhuset af. Undgå at bruge flydende rengøringsmidler eller opløsningsmidler, da disse kan beskadige overfladen eller de indvendige komponenter.
- Håndtering: Ribbon microphones are delicate. Avoid dropping the microphone or exposing it to strong vibrations.
- Fugtighed: Keep the microphone away from moisture and extreme temperature changes.

Fejlfinding
If you encounter issues with your M 130 microphone, consider the following common troubleshooting steps:
- Ingen lydoutput:
- Ensure the XLR cable is securely connected at both the microphone and the audio interface/mixer.
- Verify that the input channel on your audio interface/mixer is selected and its gain is appropriately set.
- Test med et andet XLR-kabel for at udelukke kabelfejl.
- Low Output Level:
- Ribbon microphones typically have lower output than condenser microphones. Ensure your preamp has sufficient clean gain.
- Check microphone placement relative to the sound source; closer proximity generally increases output.
- Forvrænget lyd:
- Reducer input-gainen på din lydgrænseflade/mixer.
- Ensure the sound source is not excessively loud for the microphone's capabilities, though ribbon mics generally handle high SPLs well.
- Uønsket støj/brummen:
- Tjek for jordsløjfer i din lydopsætning.
- Sørg for, at alle kabler er korrekt afskærmede og i god stand.
- Move the microphone away from strong electromagnetic fields (e.g., power transformers, computer monitors).
