现在多声道的AV中心必定内置数字信号处理器DSP,它 是环绕声重放不可或缺的中央运算装置,犹如人的大脑一 样。从杜比数字、DTS、线性PCM等各种输入信号的识别开 始,加上对信号内容的解读、进行附加处理,以及各声道信 号的分配等多种复杂工作,都由DSP逐一实时地完成。它输 出的信号经DA变换后送往模拟放大器放大,最后由扬声器 完成声音的重放。 在家庭影院中、环绕声重放是必不可少的。而与环绕声 的性能和质量休戚相关、并起着至关重要作用的器件肯定是 DSP。大多数的AV中心都选用由半导体公司专门开发的通用 器件。而雅马哈却是一个例外,10多年以来,它都坚持自行 开发,自己生产DSP器件,极力营造它倡导的cinema DSP王 国。雅马哈的成绩斐然,在业界和音响爱好者的心中已是不 争的事实。
Now multi-channel AV center must have a built-in digital signal processor DSP, which is indispensable for surround sound playback of the central computing device, like a human brain. From Dolby Digital, DTS, linear PCM and other input signal recognition began, coupled with the interpretation of the signal content, additional processing, as well as the distribution of each channel signal and other complex work done by the DSP one by one in real time . It outputs the signal after the DA conversion sent to the analog amplifier to enlarge, and finally by the speaker to complete the sound playback. In home theater, surround sound reproduction is essential. And with the surround sound performance and quality, and play a crucial role in the device must be DSP. Most AV centers use common devices developed exclusively by semiconductor companies. Yamaha, on the other hand, is an exception. For more than 10 years, it has been adhering to self-development and producing DSP devices by itself, trying its best to create the cinema DSP kingdom it advocates. Yamaha’s impressive performance in the hearts of the industry and audio enthusiasts is an indisputable fact.
