The Sennheiser MD 441-U is a highly regarded dynamic microphone, known for its exceptional accuracy and versatility. It features a precise super-cardioid polar pattern, making it suitable for a wide range of applications, including vocals and various instruments. Its robust design incorporates a five-position low frequency contour switch, a two-position high frequency switch, a critically damped internal shock suspension, and a hum bucking coil, ensuring pristine and distortion-free audio reproduction even at high sound pressure levels.

2. Key Features

• Accurate and versatile dynamic microphone with integral pop filter, ideal for vocals and instruments.
• Precise and distortion-free reproduction even at the highest sound pressure levels.
• Spring capsule mounting provides low sensitivity to handling noise.
• Five-position low frequency contour switch for tailored sound.
• Two-position high frequency switch for enhanced clarity.

3. Package Contents

Your Sennheiser MD 441-U package should include the following items:

• Sennheiser MD 441-U Dynamic Super-Cardioid Microphone
• Microphone clip
• Replacement foam wind screens (2 pieces)
• Microphone pouch
• Microphone stand adapter (European standard)

4. Setup

4.1 Connecting the Microphone

1. Attach the supplied microphone clip to a suitable microphone stand.
2. Securely mount the MD 441-U microphone into the clip.
3. Connect a standard 3-pin XLRM cable (not included) to the microphone's output connector and to your audio mixer or interface.
4. Ensure all connections are firm to prevent signal loss or interference.

4.2 Initial Placement

For optimal sound capture, position the microphone directly in front of the sound source. The super-cardioid pattern is designed to reject sounds from the sides and rear, focusing on the primary source.

5. Operating Controls

5.1 Low Frequency Contour Switch

The MD 441-U features a five-position low frequency contour switch. This switch allows you to adjust the microphone's bass response to suit different sound sources and acoustic environments. Experiment with the positions to find the ideal setting for your specific application, reducing proximity effect or tailoring the low-end for instruments.

5.2 High Frequency Switch

A two-position high frequency switch is also included, providing options to subtly boost or cut high frequencies. This can be useful for enhancing vocal clarity or adjusting the brightness of instruments without external equalization.

6. Usage Guidelines

6.1 Vocals

For vocal applications, position the microphone 3-6 inches from the vocalist's mouth. The integral pop filter helps to reduce plosive sounds. Utilize the low frequency contour switch to manage proximity effect, which is the increase in bass response when the microphone is close to the sound source.

6.2 Instruments

The MD 441-U excels on various instruments. For guitar cabinets, place the microphone close to the speaker cone for a direct sound, or further back to capture more room ambiance. For drums, its super-cardioid pattern is effective for isolating individual drums, such as snare or toms, minimizing bleed from other kit elements.

7. Technical Specifications

8. Maintenance

• Cleaning: Regularly wipe the microphone body with a soft, dry cloth. For the grille, gently remove any debris. The foam wind screens can be replaced as needed using the included spares.
• Storage: When not in use, store the microphone in its supplied pouch to protect it from dust and physical damage.
• Handling: While robust, avoid dropping the microphone or subjecting it to excessive force to maintain its performance and longevity.

9. Troubleshooting

• No Sound:
  • Check all cable connections (XLRM) to ensure they are securely plugged in.
  • Verify that the mixer or audio interface input is correctly selected and its gain is appropriately set.
  • Ensure the mixer channel is not muted.
• Distorted Sound:
  • Reduce the input gain on your mixer or audio interface. The MD 441-U can handle high sound pressure levels, but excessive gain can still cause distortion.
  • Check the low and high frequency switches on the microphone; ensure they are not set to extreme positions that might overload your system.
• Excessive Hum or Noise:
  • Ensure you are using a balanced XLR cable.
  • Check for nearby electrical interference sources (e.g., power supplies, fluorescent lights).
  • The microphone features a hum compensating coil, but extreme electromagnetic fields can still cause issues.
