I typically like to use a 2 way A+B or A or B splitter box directly after my guitar to feed to the Kemper and an AX8 ( - I am fortunate to have a KPA, an AX8 & a Helix and rate the KPA as top amp sim by a good way but there's stuff I like about the other 2 also)
Anyway, with the simple passive A/B in front I get a load of digital noise, and unrelated to the actual signal, becoming audible particularly with hi gain presets that ordinarily (i.e. with a direct input and no A/B) remain much quieter.
Yes sure I can utilise the noise gate to gate it out but that's not quite the same and I would rather not fix a problem that may be avoidable altogether.
Same A/B box to the AX8 and the Helix does not (perceptively) increase the noise floor on either of these other devices.
Is the front panel input highly sensitive?
Any ideas how I could avoid this?
Thanks.
