When the turntable enters and exits the mechanical department, it does not touch the surface of the disc, but only touches the edge of the disc to prevent the disc from being scratched.
(2) Advanced products: ALPINE, Japan.
It is characterized by BBE technology; BBE is a universal audio technology used to improve the clarity of any sound system. BBE has been successfully used by Fender guitar developer LeoFender and BarcusBerryElectronics Company in California, USA. It is adopted by many musicians and recording technicians. It has been applied in the field of car audio.
Working principle:
When you listen to live music, high notes and low notes are transmitted to headphones at the same time. However, when the speaker plays, the voice coil impedance will lead to higher frequency sound, thus delaying. This is especially true for music with strong transients (drums, guitars and pianos). BEE phase compensation (the lower the frequency, the longer the delay time) and adding higher and lower frequencies to compensate the inefficiency of speakers in these ranges have overcome this problem. This is a dynamic program-driven method to improve frequency and phase compensation.
BBE advantages:
The correct phase relationship of frequency means that music is particularly rich in existence. In other words, it's like being there. The treble is clearer and more detailed, and the bass is rich and powerful. The timbre of each string of the guitar is more obvious, which further improves the clarity. The sound of tapping and plucking is clear and exciting, so the fidelity of the piano is improved. Electronic sounds are rich and deep, while vocal music is more profound and clear.
MaxTuneSQ regulator:
MaxTuneSQ regulator has the following technical points:
1. A new phase-locked loop circuit with less jitter and a new low-noise intermediate frequency detection circuit are adopted in the frequency modulation part, and the signal-to-noise ratio is improved to 80dB.
2. The improved demodulation coil reduces the distortion (usually 0.0 1%, but usually lower than 0. 1%).
3. The high-performance ceramic filter has the function of automatic wide/narrow mode switching, which expands the selection range, which is particularly important in the signal-intensive receiving field.
4. Improved high power input characteristics.
5. The amplitude modulation part adopts new devices and circuits, which improves the anti-interference ability. The combination of the above technical features enables the regulator to play radio broadcast sound equivalent to CD audio. With the help of product TDA-7664E.
Digital phase processor:
Using the magician PXA-600 of sound stage, through advanced digital technology, the distance difference (time difference) of each speaker unit and the correction of reflected sound can be correctly adjusted, so that the frequency characteristics and phase characteristics which are called important in Hi-Fi playback of car stereo can reach the best state. It can not only correct frequency, phase and time, but also eliminate sound reflection in low frequency range. Moreover, they are all carried out by themselves. Therefore, you don't have to worry about complicated installation problems, and you can also enjoy ideal sound and sound image in the car.
