As part of my modular DAC build I've got two PCM1974 boards with I2S inputs.
I recieved a PCM2706 USB to I2S board a while ago.
Now to get these to play nice together...
With two boards set to mono differential mode via a pair of Edcor XSM 600:600 I got a week music signal through alot of noise.
I removed the Edcor trafos to make sure they weren't causing it. I then used only one PCM1794 board set to 24-bit I2S and stereo.
Now I get only noise.
Then there's the connection between the boards....
PCM2706 has
GND
MCK
LRCK
BCK
DATA
While PCM1794 inputs are
SCK
BCK
LRCK
DATA
GND
When I got the faint audio I had it connected the same way as now.
I connected MCK out to SCK in. Before the flaming begins, remember I'm new to this stuff.
I know that TDA1541A can run of just GND, WS, DATA and BCK.
Would it be able to run PCM2706 to PCM1794 via?
GND
BCK
LRCK
DATA
Leaving SCK in on the PCM1794 boards and MCK out on the PCM2706 board not connected?
