Hi All,
I've got a Denon PCM 560 autochanger I don't use much but very much like the sound of. I'd like to use it as an outboard DAC, send the digital out from my PC's sound card to it. It sounds much nicer than my Creative XFI. has anyone successfully done this?

The player has a coax connector for digital output, would that also be an input point? I'm thinking connect the digital out from my soundcard to that.

Cheers,

Obe

I'm not sure that either of those links answer the question but I only had a quick look.

I haven't done what you're proposing, but it should be possible. The digital output from your CD player won't be any use as an input I wouldn't have thought, and I can't see a way that you could easily do this without making it useless as a CD player.

You need to find the I2S lines that go between your CD transport and the DAC chip inside your CD player and tap into them. And you'll also need an SPDIF transceiver (such as the Wolfson WM8804) to convert the digital output from your soundcard from SPDIF into I2S.

The only concern I have is that your DAC chip(s) may be under software control inside your CD player and as such they may not be constantly converting.

Let us know how you get on...

I wouldn't waste time looking for I2S in a Denon of that vintage, you won't find it. It would most likely use a Sony CXD family device as its DSP/Servo and that is the chip you would have to mimick in order to add an input. In short the reverse of what is shown in the two links.
