各位，这个解码器当初宣称对应24bit/96&192的音频。我从电脑用同轴或光纤输出24/96和24/192的pcm音频数码流给它，24/96完全没问题，解码得很好。可是24/192却接收不到，是我有些地方没搞好，还是这解码根本就不能接收24/192的数码流呢？它还有一个 AES/EBU接口和一个bnc接口，我没条件去试这两接口能不能接收24/192的数码流，知道的朋友可以告诉我吗？先谢谢了！！！
ps：这问题我问过香港的代理，他们也不清楚。

（这机器是多年前全新买的，买回来以后我没拿去升级过）

你的电脑支持24、192输出吗？不是专门的数字界面的话，可能不支持192的吧

我用usb to spdif界面给信号解码器，界面是可以出24/192的。
   

USB口换3.0的试试

其实我是想问这解码器到底能不能解24/192.

   

看说明书，有很多老的解码是机内升频到24、192.外接只能到48（DVD格式）

我喂24/96信号给它，可以完美解码。
   

我的歌匠CD ONE也是这样，参数是24/192，但许多24/192格式音乐出现跳曲现象，接到欧博R2.3MK3解码一点问题没有，估计还是解码问题！！

    Dear Chenzhaoyi,

Many thanks for your mail and the expressed interest in our product line.

In fact a USB input would be the best possible signal into the D/A-Converter. For the price of an upgrade please contact your local dealer.

The USB (and all the other digital inputs) will only accept 96kHz - but with a timing accuracy of a 192kHz signal. To give you some background on this I copy sentences from our chief engineer send to a reviewer:

"1. Jitter. Whenever you are going to higher Sample Rates, you have to increase the bandwidth of the input receiver and so rise the jitter. About 15 years ago, when we went from 48K max to 96K max, we have had about two times higher jitter, but still by far low enough. So we went for 96K in serial production.
2. It is fact, that everyone can not hear above 20 kHz, but this states only for steady state signals. But the ear can hear about 4 times finer in timing, that what a 20 kHz does ring. So, you do not hear for example a 30 kHz tone alone, but you do hear if 20 kHz does arise or decay differently. So now comes the trick. We have psycho acoustically optimized the digital oversampling filter in that way, to have an relation between Pre-Ringing and Post-Ringing of 1/5 to 4/5. So our digital filter sounds like a 4-times higher sample rate.

3. When we sum up point 1 and 2. With our latest DAC technology, we have the low jitter performance of a 96K max Interface but have the timing accuracy of a 192 kHz Sample Rate. We do convert every incoming sample to 352.8 kHz / 384 kHz to get this timing accuracy. I know this is a bit difficult to understand just in some sentences, because this is mostly based on psychoacoustic, but because I am coming from making music, over recording music, I know how it should sound when playing back music.

4. And additionally, I can assure you, that there is no music that have higher frequency contents in it as about 40 K. So when you are able to play back this 40K max, with a correct timing (ringing) as I described above, than even for bats, you reproduce every recorded sound correctly. So when you have for example a 192 K file, and you play it back as 96K file, with our psycho acoustic optimized filter, there is nothing lost, but you have lower jitter. No audio content is lost.

5. Just give it a try. Take your computer and set up either AudirvanaPlus (for Mac) or JRiver (for Mac & PC) and play back a 192 K or even 384 K file on an regular 192 DAC and compare this sonically with the playback of the down sampled to 96 K sample rate, with our psychoacoustic optimized filter you can judge my saying. Trust your ears."



Mit freundlichen Grüßen / Kind regards

直接看了解释5，感觉就是安慰你的，try,不行就down,然后脑放达到192khz

回复 王叔叔 的帖子

其它的我不关心，我关心的是我的1511d解码能不能接受192信号，他已经说得很清楚：不能。
