How do you monitor S/PDIF audio outputs from Decklink

Hi,
I just got a Decklink Pro card for my PC and need to output an Adobe premiere Pro 2.0 Project to Digibetacam.
Everything went well installing it, it all plays out to my monitor, no worries. But the audio outs from the Decklink card are something called S/PDIF which is a digital audio protocol I think? How do I monitor the audio using these outputs?
Can I buy speakers that I can plug the RCA S/PDIF plugs into or do I have to get a new digital amplifier and speakers?
I.e. Any suggestions for a cheap way to monitor the S/PDIF outputs?
I don't own a digibetacam deck so cannot montor via the SDI output.

SPDIF (Sony Phillips Digital Interface Protocol - I think) is an industry standard digital audio protocol. There are many companies that offer SPDIF monitoring. One of the original solutions from Blackmagic was to use the Edirol speakers (under $200) that offer a SPDIF input. If you just want to buy a monitoring converter, M-Audio (used to be Midiman) makes several boxes between $200 - $300 (like the Flying Cow) that will convert SPDIF to analog audio, so you can plug right into your analog amplifier.
If you say "but I want to spend less than 50 bucks - how can I do this" - I have only one word for you - EBAY.

Would AES/EBU (on a Decklink HD Extreme) be the same as S/PDIF? I have a Sony amplifier that has S/PDIF but googling I found that AES/EBU and S/PDIF even when they are similar aren

From what I understand, SPDIF is basically an unbalanced AES signal. So if you have something to turn that RCA into an XLR or BNC, you can typically connect it to an AES plug and it works.

Hi,
Thanks for all the suggestions. I ended up buying some Edirol MA-10 amp/speakers. They are very styish and except analogue and digital inputs. They cost $275 Australian Dollars.

For anybody else out there still looking for a solution; we have one system using a Flying Cow, but on the other we simply split the XLR outputs with Y cables. Of course you need a monitoring system that handles balanced audio, in our case an input on the mixer that controls the input, with its output set to only go to an auxilliary output which feeds some powered monitor speakers.

It's great, works a treat. I can plug my 5.1 Audigy 2 Platinum outputs, Blackmagic Decklink outputs, and test DVD player outputs all via the same 5.1 speakers with this baby.
