XK-AUDIO-316-MC-AB and its word clock in

[hohoho]

Hello,
I tried searching the forum, but I can't seem to find the exact example.
I am to connect external mic preamps/line outs (8 channels in and 8 channels out) via ADAT (both RX and TX).
There is a BNC connector for word clock on the preamps, and I want it to be master for XK-AUDIO-316-MC-AB's word clock in BNC connector.
Could someone guide me how to configure sw_usb_audio (and probably jumpers on the board, if needed) to achieve that? Do I need something extra other than enabling XUA_ADAT_TX_EN and XUA_ADAT_RX_EN?
Thanks.
