Sennheiser MKH 8040 Specification

The Sennheiser MKH 8040 is a professional-grade condenser microphone designed for high-fidelity audio capture in both studio and field applications. It features a pressure gradient transducer with a cardioid pickup pattern, providing excellent directionality and minimizing off-axis noise. The microphone operates within a frequency response range of 30 Hz to 50 kHz, ensuring accurate reproduction of a wide spectrum of audio frequencies. It is equipped with RF condenser technology, which offers high resistance to humidity and extreme temperatures, making it suitable for diverse environmental conditions.

The MKH 8040 boasts a low inherent self-noise of 13 dB(A) and a high sensitivity of 20 mV/Pa, delivering clear and detailed sound even in quiet settings. It can handle high sound pressure levels up to 142 dB, allowing it to capture dynamic audio without distortion. The microphone requires 48V phantom power and features a balanced XLR-3M output connector, ensuring compatibility with professional audio equipment.

Constructed with a robust, lightweight metal housing, the MKH 8040 is both durable and portable, ideal for on-location recording. Its modular design allows for the interchangeability of capsules within the MKH 8000 series, providing versatility for various recording scenarios. The microphone also includes a foam windscreen to reduce wind noise in outdoor environments. With its combination of precision engineering and advanced audio technology, the Sennheiser MKH 8040 is an exceptional choice for professionals seeking high-quality audio capture in a range of settings.

Sennheiser MKH 8040 F.A.Q.

What is the optimal placement for the Sennheiser MKH 8040 in a studio setting?

The optimal placement of the Sennheiser MKH 8040 in a studio setting depends on the source being recorded. For instruments, position the microphone about 6-12 inches away, slightly off-axis to avoid direct airflow. For vocals, place the microphone at a 45-degree angle to capture a natural sound while minimizing plosives.

How can I reduce handling noise when using the MKH 8040 on a boom pole?

To reduce handling noise when using the MKH 8040 on a boom pole, use a high-quality shock mount. Additionally, ensure that the boom operator handles the pole smoothly and avoids abrupt movements. Using a low-cut filter can also help eliminate low-frequency noise.

What maintenance is required to ensure the longevity of the Sennheiser MKH 8040?

To maintain the MKH 8040, regularly clean the microphone body with a soft, dry cloth to remove dust and debris. Store it in a dry, dust-free environment and use a protective case during transport. Avoid exposing the microphone to extreme temperatures and humidity.

How can I troubleshoot audio distortion issues with the MKH 8040?

If experiencing audio distortion with the MKH 8040, check the gain settings on your recording device or mixer to ensure they are not too high. Also, inspect the cables for any signs of damage or loose connections. Try a different cable or input to see if the issue persists.

Can the MKH 8040 be used in outdoor environments, and what precautions should be taken?

The MKH 8040 can be used outdoors, but precautions are necessary to protect it from moisture and wind. Use a windscreen or a blimp with a dead cat cover to reduce wind noise. Ensure the microphone is adequately shielded from rain and consider using a desiccant in your carrying case to manage humidity.

What are the common causes of signal interference when using the MKH 8040 and how can they be resolved?

Common causes of signal interference include electromagnetic interference from nearby devices, faulty cables, or poor grounding. To resolve these issues, use high-quality, shielded cables, keep the microphone away from potential sources of interference, and ensure your audio equipment is properly grounded.

How can I set up the MKH 8040 for stereo recording?

To set up the MKH 8040 for stereo recording, use two microphones in an XY or ORTF configuration. Position them at a 90-110 degree angle to each other for XY, or 110 degrees for ORTF, with the capsules as close as possible. Connect each mic to a separate channel on your recorder.

What power supply requirements does the MKH 8040 have?

The Sennheiser MKH 8040 requires 48V phantom power, which is typically supplied by the recorder, mixer, or audio interface it is connected to. Ensure that your equipment can provide sufficient phantom power to avoid performance issues.

How can I test if my MKH 8040 is functioning correctly?

To test if your MKH 8040 is functioning correctly, connect it to a known working input with phantom power. Record a short audio clip and listen for clarity without distortion, noise, or dropouts. Check the frequency response to ensure it aligns with the microphone's specifications.

What accessories are recommended for enhancing the performance of the MKH 8040?

Recommended accessories for the MKH 8040 include a high-quality shock mount to reduce handling noise, a pop filter for vocal recording, and a windscreen for outdoor use. Additionally, a durable carrying case will help protect the microphone during transport.
