M-Audio Revo 7.1 and DTS-ES/MLP ...?

Hello,

Is it possible to decode DTS ES discrete 6.1 and matrix 6.1 with M-Audio Revolution 7.1 sound card? With WinDVD Platinium 4.5?

Can we play DVD-Audio 5.1 24bits/96kHz (MLP) without problem?

Then, can we really use this sound card as a pre-amplifier? In a first step i want to connect this card to my amplifier (5.1 pre-in) but at the end i just need 7 power-amplifiers in order to get a better sound. But I must know if it is really easy to control the global level on the card itself.

Thanks for your help.

I don't have a Revo (yet), so I'll only answer the first two...

1. The card/drivers doesn't decode DD/DTS - that is left for the software player to do. So if the software DVD player can decode the format of interest, it should work.

2. The card's hardware is capable for DVD-A (e.g., its dacs can handle the DVD-A sampling rate and number of channels), but that is only part of the equation - to play the hi-res portion of a DVD-A disc from a computer also requires a software player. The software player is where the decrypting and decoding occurs etc... So far, there is no such software DVD-A player for any card other than the audigy 2 (presumably this is a dvd forum licensing/approval issue).

Revolution 7.1 sound card, Apr 7

Price drop! Finally a cheap PCI sound card with Envy/24 audio chip.

compusa.com has the highly rated but hard to find M-Audio Revolution 7.1 sound card for $64.99 after rebate. Item 300197

This is PCI 3.3v compatible for those with a Dell server.

$35 rebate Exp 4/12/03

Hello,

thanks,

So we can say, this sound card gets hardware capability but we must await software to exploit all its capacities.

Finally, can we use this audio card like real pre-amplifier or only like one simple decoder?

Thanks for your help.

The Revo does not decode DTS in hardware, nor does it decode DD.

Decoding is done with software of choice, ie. WinDVD 4 (included) etc.

This way, it can be used as a 7.1 or 5.1 pre-amp w/ individual channel level control and bass management.

Also , it will pass through DTS to your external decoder via SPDIF.

It is great : bass management + individual channel level
