Hi all,

Am Running a pair of active L+R speakers.

I want to run a digital input to them (spdif or optical cable) to them and use the internal DACs. This avoids running dac-adc-dac-adc for the fronts.
I also want to run another 3.1 channels for surround sound on movies some how. Is there a way to split the digital signal from a 5.1 audio track to different DACs?

Thanks!

Yes. Probably the highest quality device for this is a Lynx AES16e, a PCIE card that has eight AES/EBU outputs -- most SPDIF inputs are OK with this, but you can use Canare's in-line transformers if you want a closer level match. It's expensive, so don't hesitate to buy used.

If you don't have a desktop computer that can accommodate the card, or it's too expensive even used, you can use this box from MiniDSP:

In that case, you would order the SPDIF version.

Hi,

If you have a HDMI input/output try Suptronics X6000, works without a PC. If you use a PC and have MC on it, it's a soundcard and you can use DSP in MC to do what ever you want. I tested it from TV ARC/CEC to the card and it worked without a PC connected. Toslink into HYPEX FusionAmp FA123, volume control by Hypex Remote Kit.

Have fun!

That's $325. You don't need to spend nearly that much. If you use SPDIF optical, in many cases, a very cheap passive splitter will be good enough.
If not, a powered version will work. Something like this :

I haven't tried this particular model.

I recommend not trying to split SPDIF coax. Optical tends to be more reliable, especially if distance is an issue. And if you are going to split, use optical. Even over short distances and without splitting, you can often pass 192 kHz stereo through SPDIF optical but over SPDIF coax it has issues.
