Connect the Subharmonicon's CLOCK output jack to the DFAM's ADV/CLOCK input jack using a patch cable.
               

This setup will enable the Subharmonicon to act as the clock source for both devices.

TIP: You can also clock the DFAM by utilizing the Subharmonicon's TRIGGER  output, or the SEQ 1 CLK and SEQ 2 CLK outputs to sync DFAM with a POLYRHYTHM.
