Dual TDA1541 balanced output

[resets]

I have started some breadboard tests for a fully balanced TDA1541 DAC.

finished Receiverboard: CS8414

finished Board to split I2S signal into R + L (circuit see attachment)

Actually TDA1541 is configured in the usual way. (see attachment.)

output +/- for balanced should be AOR and AOL right?

Are my suggestions correct or has something to be changed?
How would be the I/V-restitor circuit?
2x30Ohm to ground for XLR?

Many thanks in advance for your support

Can't say anything to your schematic, but have you considered to get one of those boards:

Balanced option over simultanious mode ready made...

Not sure what you are after but neither of the schematics shown do much to move things forward. Perhaps the board in post #2 is a better idea.

Probably a good idea as it is easier to implement.

By the way, how should the TDAs be implement in which mode:
Simulteanious OB/TWC to - 5V?

Which mode should be used for the CS8414 or 8412? See attached chart.

Thank you very much

I was afraid my post is misunderstanding.
Hope my feedback to weissi clearifies some of my questions.
Thank you anyway

Those boards accept I2S, in NOS I was able to run it up to 352kHz from a JLsounds I2SoverUSB. OB/TWC to - 5V is correct.
