I have my guitar connect to front input of my powered toaster, SPDIF (IN/OUT)to focusrite saffire 24 pro, with two krks connected to the interface. Laptop is a mac. Normally play with ultra low latency so I can hear the signal directly from the interface rather than through the DAW.
THE CLOCK IS SET TO SPDIF ON THE INTERFACE.
Yet I still get the odd crackle when I am playing through the interface.
I have had the input on my guitar changed and bought a new lead for guitar to kemper.
Is it possible that the SPDIF might be noisy? I thought since it was digital it wouldn't make much of a difference. Is there such a thing as a better quality SPDIF cable or do they all do the same?
Or is there a grounding problem in the room? Cables to the speakers? Issue with the interface?
Obviously keen to find the source without having to replace every cable in the room so any help would be appreciated. Any tests you could suggest to help me find the source of the noise?
I haven't noticed this noise when running the kemper through my cab, but I only do that in a band scenario so maybe I'm just missing it.
