Dac with HDMI input???

kimschips · 14th December 2007, 08:06 PM

Hello

I have read that HDMi "carry" a very high quality digital audiosignal out from example a dvd player

1. My brain ask me:
Is it possible to take an ordinary DVD player->HDMI output->Dac with HDMI input-> Interfacecircuit??-> PCM1794-> analog output??

Here i am talking two channel mode example CD /DVD /DVD-A

Anyone have a opinion / experience about that?
(a ordinay dac with HDMI input)

Thanks
Kim

no no , this is not the way it works. It goes like this:

1- HDMI source ( for example, PC with a fresh AMD videocard )
2- HDMI receiver (hacked commercial tabletop unit or the HDMi chip itself)
3- multichannel, dac compatible I2s output

the carreid digital audio signal is of very high quality 8x 24/192

Yes but is then possible to separate the 8*24/192 signal so you only got the digital stereo signal and marry it to a pcm1794 chip?

yes that is fairly easy. The really intresting thing would be to transmit 6 chnnels filtered digital audio and set up a PC basefd digital crossover.

Another one who hasn't done any research.

I too want an easy way to take pairs of sound channels to pairs of digital input speakers.
I also need a method of attenuating all the channels.

I already have dozens of digital outs using a Lynx AES-16. I want to use PGA2311 remote controlled for setting volume on monoblock style amps like hypex or GC , decisions decisions... Once I made progress withthe PGA's I 'll let you know , btw anyone saw such scheme , balanced PGA23xx with something like one of smaller PIC with internal oscillator?

Thanks for inputs

Okay can we start with keeping heads cool,, and look for the technical challenge off marry a hdmi to an ordinary dac inout CS8416 maybe?

Then we can talk surround
