AVI S 2000 MD - looking for schematic

[kunlun121]

I have this old TDA1541A-based DAC lying around and hope someone is able to share its schematic. Here are some pictures.

And can anyone explain why there are two inputs, marked 5V and 1/5V?

Now everyone, take it easy, not all at the same time…

(bump)

Surely this is a bit of a needle in a haystack, but who knows.

5v and .2v to handle SPDIf and the 3 pin balanced connector input I cannot remember the name of

no ccts available as far as I am aware, but should sound nice

Thanks

S/PDIF standard voltage is relatively low at around 0.2V, with a maximum of about 0.6V

Some motherboards output S/PDIF at very high TTL Logic levels, which can go as high as 5V

You could use any TDA1541 with Philips "SAA chipset" schematics - that particular DAC differs in a way that it has a transistor output stage.
