MKP (metallised polypropylene) capacitors are electronic components used in various audio applications. They are mainly used because of their good dielectric properties, low loss and stability over a wide frequency range. Here are some applications of MKP capacitors in the audio field:

1. Filtering: MKP capacitors are often used to build filters in audio circuits. They can be used in low-pass, high-pass and band-pass filters, helping to separate different frequency bands and eliminate unwanted harmonics.

2. Tonal correction: In audio equipment such as amplifiers or preamplifiers, MKP capacitors can be used in tonal correction circuits, allowing the frequency response of the sound to be adjusted.

3. Active and passive crossovers: MKP capacitors are important components in crossover circuits in multiband loudspeakers. They can be used in both active and passive crossovers to direct the right frequency bands to the right loudspeakers.

4. Attack time extension: In some audio systems, MKP capacitors can be used to control the attack time of a sound or signal. They can affect the characteristics of the sound, for example in compression circuits.

5. Distortion reduction: MKP capacitors can help reduce electromagnetic interference or surges in audio circuits, which can improve sound quality and minimise noise.

6. Capacitor buffers: In some cases, MKP capacitors can be used as capacitor buffers in audio circuits to help separate circuits and prevent one circuit from affecting another.

7. Interference radiation: In some audio circuits where electromagnetic interference is present, MKP capacitors can be used to radiate interference and minimise the effect of noise on the audio signal.
