First of all, I know there are tons of threads, both here and elsewhere, about connecting Kemper via spdif – I think I’ve read through them all by now… but just wanted to double check a few specific/practical things that I’m still not 100% clear on.
Also, while I’m not new to music computer tech, or audio engineering, I’ve never used spdif, and never had cause to change word clock settings - so these are admittedly blind spots in my knowledge. Have been reading up on both, but bear with me if I’ve made any incorrect assumptions!
1) Am I correct in understanding that to connect Kemper to audio interface (Presonus Quantum 2626) I just need a single cable, from Kemper OUT to audio-interface IN, and that this needs to be an RCA coaxial connector? I would only need a second cable (from audio interface OUT to Kemper IN) if I intend to re-amp?
2) The word clock thing… I usually work at 48khz, and I see I can set the Kemper to this in it’s output settings. However it’s the master/slave thing I’m not totally clear on. Is it still the case that the Kemper has to be the master clock? If so, where do I need to set this? I can see options for word clock in my Quantum 2626 control software – it’s currently set to “internal”, so presumably I’d change it to "spdif" if Kemper connected. Is this all I need to do, or do I need to change any settings in my DAW (Cubase 11) as well?
3) Will I need to change word clock settings each time I connect or disconnect the Kemper, and what happens if I forget? Or will my system automatically revert to using the Quantum 2626’s internal clock as master when I disconnect or power down the Kemper?
4) And just to make sure I’m understanding the word clock correctly – by default this is controlled by my audio interface, right? And Cubase is slave to this? I used to assume my computer controlled the word clock - but having read up on it, it seems the computer itself has nothing to do with the word clock?
Thanks!
EDIT: - I've just noticed in the Kemper's output settings, above clock speed, you can toggle the button for "internal" or "auto" - so is "auto" for using the Kemper as slave to my audio interface's internal word clock? In which case I don't have to worry about switching back and forth any word clock settings when connecting/disconnecting the Kemper? Or is there any benefit to having the Kemper as master??
