pvickers Posted November 26, 2021 Share Posted November 26, 2021 I have a Helix Floor unit routing into a FocusRite Scarlett 18i20. What I have found is I can set the Helix and 18i20 to a sample rate of 44.1 kHz and it seems to work fine. However, using the default of 48 kHz causes synchronization issues... The signal drops out, pops etc. I have the 18i20 set to synchronize using S/PDIF and the "Digital I/O Mode" set to S/PDIF RCA. I'm using the S/PDIF output on the Helix to the input on the 18i20. The cable is good quality, 75-ohm, and intended for digital links. (15 feet long.) I'm running the latest firmware on the Helix 3.11. Also have the latest FocusRite firmware and "Control" software (version 220.127.116.113). (I'm running this all using an Intel based MacBook Pro on "Big Sur" version 11.6.1.) I have already tried using a very high quality, 3 foot cable. This made no difference. Is it possible the Helix could have a hardware problem? Thanks!
