MCHStreamer in AllRate mode with TWO DACs 5 months 2 weeks ago #63274

Hi Friends,
As per the subject, I'm interested in using the MCHStreamer as a multi-channel USB device to feed two downstream DACs over I2S.
I see that in several firmware modes there are more than enough I2S channels. My question is about MCLK/BCLK/LRCLK ... there are only one each of those. In order to have two slave DAC devices, how does one connect it up?
Splitting the wire electrically into two jumper wires in parallel? Daisy-chain? Or is this not possible?

Thank you in advance. I'm a happy owner of a MiniDSP 2x4HD, and want to move a little more into a DIY direction.

Assuming your 2 DACS support the same sample rate, bit depth and serial interface formats, you can use parallel connection to MCLK, BCLK and SCLK, just feeding different SDATA lines to the 2 DACS.
