失真度低
Low distortion
在模擬音響錄放過程中,磁頭的非線性會引入失真,為此須采取交流偏磁錄音等措施,ktv音響生產(chǎn)廠家,但失真仍然存在。而在數(shù)字音響中,磁頭只工作在磁飽或無磁兩種狀態(tài),表示1或0,對磁頭沒有線性要求。
In the process of analog audio recording and playback, the nonlinearity of the magnetic head will lead to distortion. Therefore, measures such as AC bias recording must be taken, but the distortion still exists. In digital audio, the magnetic head only works in two states: magnetic saturation or non-magnetic, which means 1 or 0. There is no linear requirement for the magnetic head.
重復性好
Good repeatability
數(shù)字音響設備經(jīng)多次復印和重放,ktv音響租賃,聲音質(zhì)量不會劣化。傳統(tǒng)的模擬盒式磁帶錄音,每復錄一次,磁帶所錄的噪聲都要增加,致使每次復錄要降低信噪比約3db,子帶不如母帶,孫帶不如子帶,音質(zhì)逐次劣化。
Digital audio equipment after repeated copying and playback, KTV audio rental, sound quality will not deteriorate. In the traditional analog cassette recording, the noise recorded by the tape will increase every time it is repeated, so that the signal-to-noise ratio will be reduced by about 3dB every time it is repeated. The sub-band is not as good as the mother band, and the sub-band is not as good as the sub-band.

抖晃率小
The shaking rate is small
數(shù)字音響重放系統(tǒng)由于時基校正電路作用,旋轉(zhuǎn)系統(tǒng),驅(qū)動系統(tǒng)的不穩(wěn)不會引起抖晃,因而不---求像模擬記錄中那樣的精 密機械系統(tǒng)。
Due to the effect of the time base correction circuit, the instability of the rotating system and the driving system will not cause jitter in the digital audio playback system, so the precision mechanical system like that in the analog recording is not required.
適應性強
Strong adaptability
數(shù)字音響所記錄的是二進制碼,各種處理都可作為數(shù)值運算來進行,并可不改變硬件,僅用軟件操作,山東ktv音響廠家,便于微機控制,故適應性強。
Digital audio records binary code, all kinds of processing can be carried out as numerical operation, and can only be operated by software without changing hardware. Shandong KTV audio manufacturer is convenient for microcomputer control, so it has strong adaptability.
便于集成
Easy to integrate
由于數(shù)字化,因而便于采用---規(guī)模集成電路,并使整機調(diào)試方便,性能穩(wěn)定,---性高,便于大批量生產(chǎn),可以降低成本。
Because of digitization, it is easy to use - scale integrated circuit, and make the whole machine debugging convenient, stable performance, high reliability, convenient for mass production, can reduce the cost.
