Default choosing TDA1543

Hello guys,

TDA1543 is the simplest to use, im looking for one myself.

The TDA1543 you can connect directly to the spdif receiver like CS8412 or anything with the same kind of data outputs.

Use a -60db 1khz sine and select for low distortion .. should be a start.

Hi,

Tried that today.

My sound card isn't very good!

Useful nonetheless..





Kind regards,

Ashley
