PT P-1A I2S input question

[marcus1]

Hi

I am trying to connect the I2S output from my DIY CDPRO2 player to the Perpetual Technologies P-1A DAC I2S input.
My problem is that I'm not sure what clock/data connections from the CDPRO2 (see table below) to use so that it matches the I2S P-1A connector.

cd pro2 I2s output:
pin1 EF=====C2 error flag
pin2 SCLK===serial clock
pin3 WCLK===word clock
pin4 DATA===Data
pin5 GND====ground
pin6 V4=====Versatile output


Hopefully, I have attached a diagram of what i believe is the rear view of the Perpetual Technologies P-1A I2S connector. Could someone please advise what connections from the CDPRO2 (table above) I should use to connect to the P-1A.

I guess the obvious ones are:

CDPRO2 pin2 SCLK==serial clock to P-1A serial clock pin
CDPRO2 pin4 DATA===Data to P-1A Serial Data pin
CDPRO2 pin5 GND===ground to P-1A ground pin

The remaining outputs I don't know or even if there are needed. Any help appreciated.

Thanks

You need to connect WCLK (Word-Clock) too. It's named LRCK, WCK or something like that ...

Maybe your OS-Filter or DAC needs MCLK too (in most cases 128, 192, 256, 384 or 512 x fs) ...

I know this thread is OLD (!) but did you ever get this working? My PT P1A and P3A are sitting gathering dust because I could never get any sound via I2S...

Thanks
