Sennheiser MKH 40-P48 Specification

The Sennheiser MKH 40-P48 is a professional condenser microphone designed for high-quality audio recording and broadcasting applications. It operates on a pressure-gradient transducer principle with a cardioid polar pattern, making it highly effective in capturing sound from the front while minimizing noise from the sides and rear. This feature makes it suitable for a wide range of recording environments, including studios and live settings.

The microphone is engineered to deliver an exceptionally flat frequency response ranging from 40 Hz to 20 kHz, ensuring accurate and natural sound reproduction. It incorporates RF condenser technology, which provides superior moisture resistance and a low inherent self-noise level of approximately 12 dB(A). The sensitivity is rated at 25 mV/Pa, enabling the capture of subtle audio details even at a distance.

The MKH 40-P48 is powered via 48V phantom power and is equipped with a high-pass filter and a 10 dB pad switch to handle high sound pressure levels, offering versatility in various recording conditions. Its robust construction and compact design enhance its durability and ease of handling, while the included windshield helps reduce wind noise and plosives.

Sennheiser's meticulous engineering ensures that the MKH 40-P48 provides a pristine audio signal with minimal coloration, making it a preferred choice for professional audio engineers and broadcasters. Its reliable performance across diverse audio applications underscores its reputation as a versatile and high-performance microphone in the industry.

Sennheiser MKH 40-P48 F.A.Q.

What is the optimal placement for the Sennheiser MKH 40-P48 in a studio setting?

For optimal placement in a studio, position the MKH 40-P48 about 6 to 12 inches from the sound source, slightly off-axis to reduce plosive sounds. Use a pop filter for vocals and ensure the recording space is acoustically treated to minimize reflections.

How can I reduce handling noise when using the MKH 40-P48?

To reduce handling noise, use a shock mount designed for the MKH series. Additionally, handle the microphone stand or boom gently and ensure cables are not in contact with surfaces that can transmit vibrations.

What are the steps for cleaning and maintaining the Sennheiser MKH 40-P48?

To clean the MKH 40-P48, gently wipe the exterior with a soft, dry cloth. Avoid using liquids or cleaners. For maintenance, store the microphone in a dry, dust-free environment and periodically inspect connectors for corrosion.

Can the MKH 40-P48 be used outdoors, and if so, what precautions should be taken?

The MKH 40-P48 can be used outdoors, but it is recommended to use a windscreen or blimp to protect against wind noise. Additionally, avoid exposure to extreme weather conditions and moisture.

How do I troubleshoot a low output signal from my MKH 40-P48 microphone?

If experiencing low output, check the XLR cable connections, ensure phantom power is enabled on your audio interface or mixer, and verify the gain settings. Test with a different cable or audio interface to isolate the issue.

What is the best way to power the MKH 40-P48 microphone?

The MKH 40-P48 requires 48V phantom power, which is typically supplied by most professional audio interfaces, mixers, or dedicated phantom power supplies. Ensure your device provides consistent 48V power.

How does the MKH 40-P48 perform in high humidity environments?

The MKH 40-P48 is designed with RF condenser technology, making it more resistant to humidity compared to traditional condenser microphones. However, it is still advisable to avoid prolonged exposure to high humidity.

What type of polar pattern does the MKH 40-P48 use and how does it affect recording?

The MKH 40-P48 features a cardioid polar pattern, which captures sound primarily from the front while rejecting noise from the sides and rear. This makes it ideal for isolating the sound source in noisy environments.

How can I prevent feedback issues when using the MKH 40-P48 in live sound settings?

To prevent feedback, position speakers in front of the microphone, use directional speakers, and apply EQ to reduce frequencies prone to feedback. Additionally, keep the microphone gain at a moderate level.

What accessories are recommended for the MKH 40-P48 to enhance its functionality?

Recommended accessories include a shock mount to reduce handling noise, a windscreen for outdoor use, and a pop filter for vocal recordings. A high-quality XLR cable is also essential for optimal signal transmission.
