I am looking for a modern PCI or Firewire-based sound card featuring one SPDIF input and three to four SPDIF outputs which may be used concurrently under Windows XP. DirectSound drivers are required. D/As are optional. Flexible on price.

Any suggestions?

RME Hammerfall HDSP 9652 has 3 optical SPDIF outputs.

A bit spendy, though.



If you are not concerned with with the small degradation you will get with using a toslink distribution amplifier, you can use what I do, which is a 4 output Toslink Distribution Amplifier (Splitter). Much cheaper solution.

Toslink Digital Splitter

Then you will need a Soundcard with a single input and output.

Thanks for the reply. I will download the RME manual. But, to clarify, I intend to drive different signals to each SPDIF output simultaneously. So, a dist box won't work for me.



Ah, more of your crazy cool testing?

Sounds interesting.

I hope the RME HDSP 9652 is up to the task.

On my primary stereo rig, I am experimenting with ambience recovery. I'd like to use some MTMs that I built last year for the rear channels. But, they use DCX2496 electronic crossover, which has digital inputs. I want to keep all signals, including the ambience channels in the digital domain until amplification.

I found a piece of SW on SourceForge which implements Dolby ProLogicII music mode via a PC through a soundcard. So, I'm planning on building a quiet PC to run this SW.

The standard answer for this is the Lynx AES-16. 8 pairs of ditigal outputs. It actually is AES/EBU out, but you can generally convert this to spdif-compatible with an xlr->rca cable. If not, you may have to get transformers to do it.

Alesis sells the AI-4 which is a 4-spdif<->ADAT box. 8 channels supported at 44/48, and I think you can run at 96 with a reduced channel count. Pair it up with say an Emu1212 which supports ADAT

The Emu 1820 versions have two useable spdif outputs - one on the pci card and an optical output on the dock.

Hi Edwood,

are you sure the RME card supports S/PDIF on all 3 optical ports. I was looking into that a while back and it appeared as if it only supported ADAT on these optical ports.

This would be a pretty cool solution if you could just drive these ports in S/PDIF mode like a multichannel card and get all channels of a 5.1 system on digital outputs.

Do you know whether this will work with the NVIDIA audio drivers that come with Theatertek?

Cheers

Thomas

...seems like it will work also. It has three SP/DIF outs via a four-pole mini-plug. The Creative drivers disable digital outputs when the 2ZS is performing Dolby decoding, but when used in conjunction with MatrixMixer, the board will be operating as a pass-thru six channel output card, which should be fine for my purposes.

The drivers appear to feature a bit-perfect mode which bypasses any up-sampler.
