EMU 0404 supports 24 bit/ 192khz SPDIF output?

[liangzhao]

I am looking for a good SPDIF output stuff as I have a DAC can take SPDIF as input. I was thinking whether EMU 0404 is a good choice. does it support 24 bit/ 192khz SPDIF output?

Thanks

Per the info on the E-MU web site here:

E-MU Systems - 0404 USB 2.0 - USB 2.0 Audio/MIDI Interface

it only supports 44.1 to 96 kHz sample rates on its digital I/O.

 

[liangzhao]

any suggestions on USB sound card that support 24bit/192kHz SPDIF output?

 

[sejarzo]

What source material do you have that demands 24/192?

There's quite a bit of controversy over whether DAC chips that can process such streams actually do a worse job at 192 kHz than at 96 kHz.

Synchronization
Internal crystal sync at 44.1, 48, 88.2, 96, 176.4, 192kHz
External sample rate sync via
- Optical S/PDIF (44.1 - 96kHz)
- Coaxial S/PDIF (44.1 - 96kHz)
by the way, it only say the external sample rate, it does not say anything about SPDIF output. Any one who own this can give an answer?

thanks

Yes, I do own it--that's why I responded.

There are a couple of different statements about the digital I/O capablities that confused me.......but I did find the newest documentation shows that on a PC, the S/PDIF output does work at 176.4 and 192 kHz.

However, if you use a Mac, the digital output is indeed limited to 96 kHz.

You can download the E-MU manual here; the info is at the bottom of the sidebar at left on page 18:

E-MU: Downloads

You are aware that you must be operating the 0404 USB via an ASIO-capable application in order to route the audio data stream via the USB input to the digital outputs rather than the internal DAC and main analog outputs, correct? There's no way to shift the output channels by using the standard Windows driver.

 

[sejarzo]

I'm sorry, I didn't catch that you might be referring to the E-MU 0404 PCI rather than the 0404 USB.

And once again, I wish that E-MU never decided to use that ridiculous numbering system.

If it's the PCI card, from on page 17 of the new 0404 PCI manual (there are two versions of that card, so keep that in mind):

"The S/PDIF input and outputs are usable at the 44.1kHz, 48kHz and 96kHz sample rates."

Again, sorry for the confusion!

Yes, the document is misleading. Thanks a lot for your info. So, it do support 24/192. Do you think it is a good buy for $160 only for Digital output?

$130 at Music123.com with free shipping. And yes, I would say that it is worth it. No doubt there are better quality alternatives, but not for anywhere near that price.

I wish that I could verify that the digital output works at 192 kHz, but I have neither (a) source material at that rate, or a software upsampler that will work at that rate nor (b) any device that can accept 192 kHz input!

I might just be ignorant of something new, but I would tend to agree with Aura that there is nothing else in that price range that could provide 192 kHz output. I just checked again, and the 1010 I/O daughter card that is used in the 1212M PCI system is only capable of 96 kHz max in/out via S/PDIF, as for the 0404 PCI.

 

[sejarzo]

Still, just out of curiosity......how do you intend to get a 192 kHz to the 0404 USB via the USB cable in the first place?

You are right. 96 kHz is good enough, however, most the latest DAC do accept 192 kHZ, for example, http://www.head-fi.org/forums/f5/rev...re-amp-269458/.

Cheers!

DVD-Audio outputs 24/192 format and winDVD and powerDVD play that format (boa)

 

[sejarzo]

But those players are not compatible with the ASIO driver for the E-MU, which is required to access the S/PDIF outputs on the 0404 USB, are they?

How many DVD-A's actually had any 24/192 material on them? I was under the impression that virtually all had only 24/96 resolution on the hi-rez stereo portion.
