Sennheiser MKH 20 Specification

The Sennheiser MKH 20 is a professional omnidirectional condenser microphone renowned for its exceptional acoustic performance and versatility in a wide range of recording applications. Designed for critical studio recordings, orchestral captures, and broadcast environments, the MKH 20 utilizes an RF condenser design that ensures low inherent self-noise and high sensitivity. This microphone operates with a frequency response ranging from 12 Hz to 20 kHz, delivering a natural and transparent sound profile that accurately reproduces the nuances of the audio source. The MKH 20 features a symmetrical transducer with two backplates, which contributes to its precise omnidirectional pickup pattern, maintaining consistent sound capture across all frequencies and angles.

Its low noise floor, rated at 10 dB(A), coupled with a high maximum SPL handling capability of 134 dB, makes it suitable for both delicate and powerful sound sources without distortion. The microphone is equipped with a switchable low-cut filter to minimize low-frequency noise interference, such as handling or wind noise, enhancing its adaptability in diverse acoustic settings. The MKH 20 is constructed with a robust metal housing that provides durability and effective RF shielding, ensuring reliable performance even in challenging electromagnetic environments. It operates on standard 48V phantom power and is compatible with various professional audio equipment. Combining advanced technology with Sennheiser's renowned build quality, the MKH 20 stands out as a versatile tool essential for any professional audio engineer's collection.

Sennheiser MKH 20 F.A.Q.

How do I connect the Sennheiser MKH 20 to my audio interface?

To connect the Sennheiser MKH 20 to your audio interface, use a high-quality XLR cable. Plug the female end into the microphone and the male end into the audio interface's XLR input. Ensure your interface provides phantom power, as the MKH 20 requires it to operate.

What is the best way to position the MKH 20 for recording orchestral performances?

For orchestral recordings, position the MKH 20 above the conductor's podium, pointing towards the orchestra. This placement captures a balanced stereo image. Adjust the height and angle to suit the acoustics of the venue.

How can I minimize wind noise when using the MKH 20 outdoors?

To minimize wind noise, use a windscreen or a blimp with the MKH 20. These accessories effectively reduce wind interference while maintaining sound quality. Consider using a high-pass filter to further mitigate low-frequency wind noise.

What maintenance is required to keep my MKH 20 in optimal condition?

Regularly check the microphone for dust and debris, and gently clean it with a soft, dry cloth. Store the MKH 20 in a protective case when not in use to prevent physical damage. Avoid exposing the microphone to extreme temperatures and humidity.

How do I troubleshoot if my MKH 20 is not producing any sound?

First, ensure the XLR cable is properly connected and the audio interface is providing phantom power. Check that your recording software is set to the correct input channel. If the problem persists, test with a different cable or interface to isolate the issue.

Can the MKH 20 be used for recording dialogue for film?

Yes, the MKH 20 can be used for dialogue recording in film due to its excellent transparency and low self-noise. For best results, use it in a controlled environment and employ a shock mount to reduce handling noise.

What is the polar pattern of the Sennheiser MKH 20?

The Sennheiser MKH 20 features an omnidirectional polar pattern, capturing sound equally from all directions. This makes it ideal for ambient recording and capturing the natural acoustics of a space.

How do I prevent handling noise when using the MKH 20?

To prevent handling noise, use a high-quality shock mount and boom pole when operating the MKH 20. This setup isolates the microphone from vibrations and handling sounds, ensuring cleaner audio recordings.

Is it possible to use the MKH 20 for podcasting?

Yes, the MKH 20 can be used for podcasting, providing clear and natural sound quality. Ensure your recording environment is quiet, and consider using a pop filter to reduce plosive sounds for optimal results.

What should I do if my MKH 20 microphone gets wet?

If your MKH 20 gets wet, immediately power it off and disconnect it from all equipment. Gently dry the exterior with a soft cloth and allow it to air dry completely before using it again. Avoid using heat to dry the microphone. If problems persist, consult a professional technician.
