CS4397 dac

[leo]

Going by memory those larger 100uf caps are for the op-amp decoupling, feel free to change them

Any one manage to successfully input I2S directly to this DAC board?
I have input the appropriate leads from an I2S output in place and (I think) configured the chip for I2S input. Nothing. I really don't know that much about this so any thoughts would be helpful. The I2S board is the one from twisted pear.
The mistake i know i made was not to check the DAC board for operation before any mods (D'oh) and I did have to repair a bent and mis-soldered pin on the chip so maybe it is a board failure, but thought I would ask before I return the board to pre-mod configuration and see if it works at all. Thanks.

Hi,

I read your Buffalo thread and so I am interested in your statement: Does this CS4397 DAC reach your Buffalo Mod?

Hi Thomas,

No,imo its not as good as the modified Buffalo but not many other diy dacs I've tried so far are either

The CS4397 is capable of very good performance though with some work and has the advantage of being cheap

Hi to all members:

After some searchs and readings, I decided to do some mods and now it did not work. The blue LED light up, that indicate it´s on, but no sound out :-/

Many thanks in advance for your help.

You will need to read this whole thread as there are lots about problems created when modifying these boards.

But you did persevere and get it working..

But Richard, I am confused with your transformer wiring though, did it come with pigeon English instructions, how is it working?
Your primaries are out of phase with each other and so secondaries have had to be wired out of phase as well. I would have thought your "light bulb tester" would have protested?
The norm is; L-1, N-4, link 2-3. and white-8,white-5 and black-6,7. Apologies if I have it wrong.
As an observation, it could have been easier to bypass the output caps and the "mute chip" with links under the board. Just remove the output caps and add new ones between board and phonos.
