Easiest way is to use a re-sampler plugin on the playback software you use (e.g. PPHS in Foobar2k) and set it to 24/96.

Is it called micro BNC cable?

The is called a u.fl cable

I connected the WaveIO to FIFO via the isolated I2S and work excellent, but no sound when connect through the SPDIF, neither the isolated or non-isolated. Even directly connect it to BIII, still no sound. Scope shows no output from the SPDIF. Please advise what may be the problem.

With your permission let's try to solve this privately to keep this thread clean. I'll send you an email right after I'll finish writing this reply.

To all the owners of the WaveIO card. Keep it carefully, because it is sooooo good that some people try to steal it !!
It is world glory for Lucian !

I am delighted to be able to listen to it soon.....

Many thanks Lucian !

No problem just trying to solve tour issue as best as possible! Well, I'm still thinking at what I should learn from this not so pleasant experience as it took me by surprise...

Is it possible fixing the output rate of the board to 24 bit / 96 kHz with the software? I mean, that incoming lower rates would be up sampled, and incoming higher rates would be down sampled. With the fixed sample rate out of the Wave IO board it would be possible to connect the board via I2S to the DCX 2496 without using the SRC CS 8420?
I am very pleasure, for some details or solutions!
Thanks! Rainer

Now sure about the sample rate but from what I can remember, the DCX does use the I2S but in master mode (generates the Word clock and bit clock) thing that WaveIO is also does... so two masters on the same I2S bus will not be a pleasant view... Most likely I have to change the firmware for this and allow your DCX to control the I2S bus accordingly. I'll do it gladly but daughter is on the line (please see below) Anyway, I'm ready to be wrong!

Nice and slow.... To be honest I'm still working in parallel on a project that I hoped to be ready in January... well it's still January and I'm still optimistic but things got wild here when this project was 90% ready! Yes, I've been through this before, with actual WaveIO... jrling has asked about the board but I will like to give details after I'll see it fully implemented.

Here is a link to those that I'm using right now for testing purposes. Please note that are coming with different lengths and, if possible, please choose the shortest one that could accommodate your connections.
@ barrows & TheShaman: thank you!

Cheers,

You are not at all responsible Lucian ! You can't do anything against dishonest people !

But I am just thinking that maybe there is a solution. I don't know how you call it in english and if it exists for international postage, but here in Switzerland the post office has an option that forces the postman to look at identification papers before giving the parcel. It is very effective against steal but it costs approximately 12 Euros more than standard delivery cost.
Maybe you could use it as an option for people who are afraid of a steal......

Hi Lorien,
Thanks, for your fast replay! My Behringer DCX 2496 is not in master mode anymore, because I build out the master clock and use a SRC upgrade board (from Peter Oettle) with own low jitter master clock instead. My intension is to use the Wave board as master via I2S in fixed mode 24bit / 96kHz and also use the clock from the Wave board (24.576 MHz) as master clock / in master mode. In this case I would extract the Oettel SRC upgrade board completely. Would this be a solution? Or is it the wrong way?
Thanks, Rainer

To Lorien or anyone who have assemble the board, can I have a clear description the true current requirement for the board since the beginning of this thread Lorien mention the board needs about 600mA of current but from the description of DDDAC guy it need 380mA !!! So which is the right one as I'm in the middle of finding the right pars for the PSU.

[rickmcinnis]

Sorry that I am late to this discussion. I was told of this device and want to give it a try.

I see the mention of the daughter board and I have looked through pages and pages of posts but there are too many to read them all.

Would someone please tell me what this will do.

I am definitely ordering the WaveIO and as any obsessed audiophile I want the best possible result.

THANKS in advance!

With NDK oscillator (as in mine), the latter.

I get it now. Mine is with the tiny small oscillator (not the Expresso clock). Definitely a NKDs. So 380mA....

Thanks massimo...!!!

There were some posts in October 2012 regarding WaveIO power consumption that lead to the ~380mA suggestion, though some measured only 320mA so 380mA is actually the conservative estimate if I recall correctly.
