AES/EBU与SPDIF(光纤)的比较

如题,AES/EBU与SPDIF(光纤)区别就不用提啦,只是本人不了解哪个更好,好在哪方面?本人只是听歌看电影,特开此贴,广开言路,请大大们开讲吧。

非平衡的RCA式SPDIF最不理想(民用光纤),过来是平衡的AES/EBU(广电用光纤),最理想还是TOSLINK,几乎无损

哈哈,我是第一次看见这种说法,不知道你是不是。

同意,9632用的就是AES/EBU的线!

I've heard some stories on the Metric Halo list about some manufacturers' implementation of ADAT being less accurate when it comes to data (losing some packets). But I am CERTAIN that ADAT per se is not a problem as long as you get your clocking right. I have complete confidence in RME's implementation of ADAT, in Metric Halo, and reportedly, also, Yamaha at least at this point. Other than that data issue, the data integrity of ADAT is just fine.

In general, in terms of reliability, professionality, stability, and performance, my personal preference would be:

MADI (preferrred for multitrack)

AES/EBU (second preference)

TDIF

ADAT

Firewire

ADAT is more convenient to wire and run but the non-locking connectors give it lower marks. But the fact that TDIF patching involves both send and return in one cable gives it somewhat lower marks. Firewire is cool, but the latency is potentially higher. The self-clocking in AES/EBU give it higher marks as far as reliable locking even without a WC line. But you need more cables with AES/EBU. With MADI you can get reliable transfer of 32 to 64 channels in a single pair of BNC or SC optical cables. MADI is the most reliable, professional solution.

Hope this helps,

东芝光纤和ADAT口光纤最差了,因为使用1。2毫米的塑料光纤(这个居然也能叫光纤?)抖动什么的非常差,唯一好处是电隔离的,对设备与设备间低电位没要求。
接着比较差点的是SPDIF的RCA接口,同轴是没问题,但是好多民用设备的输出输入特性阻抗不标准,包括RCA PHONE的插头也没有很理想的75欧姆阻抗(偏低好多)造成整个传输路径反射很多。
接下来是XLR的AES/EBU,主要的问题是插头线缆也是需要仔细考虑。
比较理想的是现在AES3采用BNC的连接器的形式,BNC75欧姆插头和线缆都比较成熟。
