From Classic to Plus

djsainz · Post by **djsainz** » Tue Jul 31, 2007 4:11 am

I am sure I heard it was not possible to just simply swapping the octopus cables from classic to plus in order to get AES/ABU. If there is a way, like just swapping the addon plates. What are the prices if anyone has any idea, or even are they for sale?

Thanks.

yes you have to change the plate. Ask Garyb (planetz pseudo), i think he had few left... It is quite easy to do ; there are 4 or 5 plastic screws to remove and it is done...

I upgraded my classic plate to a plus plate about 6 months ago (ordered by email/phone from Ralph at (then) Creamware, now Sonic Core). At just under 290 euros (including tax) it's expensive, but if, as in my case, you really need the balanced i/o's at +4dB and the AES/EBU i/o's then it's definitely worth the upgrade.

definitly agree... except if you just record synth. Thanks to the aes ebu you can easily involve hardware stuff (EQs, comp, reverb...) within your project (e.g. : insert of the scpe mixer) as soon as the hardware has the aes-ebu option (by far better than the spdif

). As for the in/outs, the aes-ebu offers additionnal in/outs to the analog ones. Depending on teh price you pay, buying a "plus" scope project could be a good option too ; just use the cinch outs of your first board for monitoring

It may be possible to simply use an adapter plug and switch the digital I/O type in software. This is how Lynx soundcards and Kurzweil products function.

No, it's not possible to simply use an "adapter plug" (whatever you may mean by that - you can't simply plug in the octopus from the "plus" plate into the "classic" plate) and simply switch the i/o in software. Indeed the scope software automatically detects which plate is installed. If you had bothered to check your facts before posting, you would know this to be the case.

You misunderstood. The adapter plug I am referring to is for changing RCA end of the SP/DIF cable to an XLR plug, not an adapter for the entire octopus cable assembly. I did this on my Plus card to change the AES/EBU output to SP/DIF and it works absolutely flawlessly.

Even if you had not misunderstood me, your rudeness is completely uncalled for. Please do not respond to any of my posts in the future.

In that case I apologize. I don't mean to be rude but I do still think that your original post was less than clear - it seemed to undermine what I had said previously (though in the light of your clarification I realize that was not your intention). Let's leave it at that. I will, of course, respect your request not to respond to any of your posts in future.

May be off topic: you can use an AES output going into an SP/DIF input with the correct cable - it needs a resistor in-line to change the impedance. I have such a cable, using it from an Apogee A/D AES output into a Pulsar2 SPDIF input. The same should work the other way (SPDIF output to AES input) although I've never tried this. It was made for me so I can't supply any details about it but I'm sure searching around on the internet will yield some useful results.

yes, sp/dif and aes/ebu are the same signal. aes/ebu is balanced and a hotter signal(+4 as opposed to -10). hosa makes an inexpensive converter:

Also, there is an interesting article here for anyone interested in the details of S/PDIF to AES/EBU interfacing (or vice versa):
