Signal-to-noise ratio question

[YaKostia]

Hi.
When I load more factory presets, I can see that the output level indicators barely move. Should I increase the volume output presets to get the best signal-to-noise ratio? Should I adjust preset level until “hot” signals “tickle” the red LEDs on the front panel OUTPUT Click?

There are no output level indicators on the front panel of the Axe-Fx. Those green/yellow/red light-"bars" are input level indicators. Or are you talking about the indicators on the I/O-page?

I meant OUTPUT Clip LED

OK. No, the OUTPUT Clip LEDs should never appear (even if they do appear before actual clipping). There is a very good instructional video about that topic by forum-member Chris: Why are my Axe-Fx Clip Lights turning on? What is Clipping? | Katsu Kuri Media Blog.
