Most Common Microphone Parameter Controls

- Sep 27, 2018-

1. Roll-off filter

Because the microphone sometimes records low-frequency sound (such as truck or mechanical noise) into your recording, the roll-off filter can eliminate this problem from the frequency. The filter cut-off frequency is set at 40 to 100 Hz, usually 60 Hz.

2. Low cut

Many condenser microphones have higher output levels than dynamic coils and aluminum ribbon microphones. If you record a sound source that has a large sound (such as a snare drum), the output may be too large to cause the microphone to be overloaded. A -10dB or -20dB attenuation reduces the output to prevent overload.

3. Directional selector

Most large diaphragm condenser microphones support multiple directionalities and can be selected with a toggle switch. Some change from one directivity to another, and there are continuous changes. Many recording engineers use only heart-shaped directivity, and a clever recording engineer adjusts according to different situations to make the final recorded sound better.

Remember: the microphone's own parameters are very useful.

1. A high pass or roll-off filter can be removed based on the noise frequency.

2. Input attenuation control can prevent overload.

3. The directional selector allows us to choose the most appropriate directionality according to the actual situation.
