1. Nerve wire: mainly refers to signal wire that transmits low level (millivolt, microvolt) and small current. Generally, the nerve wire is used for audio and video. The plugs at both ends of the higher grade nerve wire are gold plated RCA plugs, and the surface of the wire is coated with an anti-static protective layer.

2. Fever line: mainly refers to the sound box signal transmission line with large section and many strands. High quality fever wire is made of oxygen free copper and other materials.

3. Cooker: The so-called cooker is similar to the friction period of mechanical machines, that is, after the audio equipment has been working for a certain time, the temperature in the machine is the same as the ambient temperature, so that the working state of amplifiers at all levels can reach the optimal point, and the sound reproduced at this time is the best.

4. Motorcycle: The so-called motorcycle originates from Modify in English, which means modification. Fans replace and transform the components or circuits in the sound system to upgrade it, which is called a motorcycle.

5. Explosion: The so-called explosion refers to the deafening atmosphere produced when the music reaches its climax when the audio equipment is replayed.

6. Bile machine: Bile machine refers to an amplifier made of electronic tubes. The warm and transparent sound quality of the tube amplifier is unforgettable to the older generation of enthusiasts.

7. Stone machine: The so-called stone machine refers to an amplifier made of transistors.

8. Gallstone machine: audio equipment made of electronic tubes and transistors. Generally, the electron tube is used as the pre amplifier and the transistor as the post amplifier.

9. Annular transformer: The so-called Annular transformer refers to the annular transformer, which has less magnetic leakage compared with the ordinary transformer.

10. Large pond: large pond refers to power filter capacitor, generally 10000 μ Large capacitance above F.

11. Beautiful sound: refers to the sound reproduction quality of audio equipment is very good, meeting the requirements of high fidelity.

12. Resolution: refers to that the playback sound of audio equipment has a certain transparency, giving people a feeling of "clear to the bottom".

13. Staining: The so-called dyeing refers to the sound that is not found in the playback sound due to the resonance of other objects or materials caused by the vibration of sound waves in the playback process. It is harmful to the playback effect.

14. Mic head: refers to various microphones.

15. Supplement: refers to the high-quality components used in the transformation of the sound system.
