I don't want to bin this CD player

[NVD33]

Hi,

I own a Cairn Ecrin CD player, the CD transport is a Philips CDM12.1 with a tray loader L1210/11, the laser is dead for sure. The player has a good DAC board and nice power supply board in working conditions. See attached pictures.

I would like to make use of the DAC, the source will be a Logitech Squeezebox Classic or SB3 which has a SPDIF output.

I have no schematic of the CD player. On its DAC board I can see a CS8412 (receiver), a SM5813APT (filter), 2 PCM63P (DAC chips), 2 OPA2604AP (op amp)and transistors for output stage.

I have some knowledge on DAC but not enough to do what I would like to do on this project. Help to get me started on this project will be much appreciated,

Vince,

Look for at the datasheet of CS8412 the S/PDIF input are pin 9 signal & pin 10 ground

Hi,

Any chance that connecting spdif output of the squeezebox to pins 9,10 of the CS8412 I will get music at the analog output at the Cairn DAC board ? It would be great.

Thanks for your reply,

Thanks for your reply,

yes, you probably would. be sure to disconnect the old input at 9,10 and use the resistor+capacitors from the schematic above.

Hi,

I have succeeded, the DAC is singing now and its sound is very nice, I am very happy.

Thanks a lot to both of you for your valuable help,

Vince
