i know just wanted it.is that possible ? its convenient because i have very good soundcard and optical is less hassle.and will have switches from windows panel just using remote.
-- i learned many things from yours,its just interesting,i have NO studies in electronics ,managed somehow to assemble a lot of things,and got them to work very well,even understood how polarization in a sat tuner works.so this NOS is very interesting because its NOS and how to h'ell to you overcome the problem of electron being created at the juncture where the i2s is decoded ,because it will maintain its properties up to your ears - please respond to that with high pull and led

Sorry, your request for support is not in scope of this thread and too broadly to give a useful answer. if you ask my help and experience to help you on your project, may be you can just email me with your specifics and I can see if I can give you some advice. this thread if for my dac, so lets stick to that. thanks for your understanding...

and about your DAC NOS pcm1794 dddac waveIO .. -
I saw on your pcb that the current limit - limiting resistor for 1x ic pcm1794 is 10R how that can be? will it last long enough ? pcm1794 digital section consumes 45ma at 24/192khz divided from 3.3V equals 73.(3) ohms.can you explain PLeASE ! i just like music im not engineer .why not 5v ?

the whole section, digital and analog takes 55 mA, so power dissipation is .055 x .055 x 10 = 30mWatt. it is 1 watt resistor, so NO problem what do you mean with why not 5 volt?

One thing shouldn't be the current limited for pcm1794 ?
so 55ma for analog + 55 for digital but different supplies 3.3v VS 8v
DIGITAl=i got the message 45 + (2x5ma) for Fm0-pin11+ Fmt1-pin12

-i ment V=RI ,please be short and on theme because im learning from it as many others,and i cant be disrespectful for 1 not 1+x ,we dont solve here AC currents vs activity of solar flares

I am afraid, you are mixing quit some things up... this goes beyond normal thread communication. your ideas of Ohms law has nothing to do with implementing the pcm1794. there is no need for nay current limiting. the resistors you see in the design are RC filters to filter power supply noise or to decouple the digital path. Not sure what to answer more? if any one has a better answer, pease jump in ! specially on solar flares I am not an expert.

I have found this output transformer shoot out for the DDDAC1794 on the site of Audio Creative magazine.
Link: DDDAC 1794 deel 5
I don't speak dutch, the little what i understand is the Cinemag CMLI 15/15B is good for the price.
If this is usefull for all, maybe someone from Netherland can post a summary of that test in english.
Thank you. Johann
