1. When I play my guitar on the most expressive pickup with Hi-Z enabled on Zoom, sometimes I see a red light on the signal indicator. What does it mean? I don't quite understand because with 32-bit, such a picture should be missing.

2. I have a noise when using Behringer B2 Pro with Direct Monitoring. How can I Improve that?

Thank you.
 
Chances are maybe nobody here has that interface, but it might still help if you gave some more information about your entire signal chain, like whether you're connected to a Mac or PC, and you've correctly set the mode to 32-bit float in the Zoom's control panel, and confirming the audio files captured in your DAW are actually 32-bit float audio.

From my quick look at the manual, the red light means the *output* level is too high, and you're sending a clipped signal to your output device, like headphones, monitors, direct streaming, whatever.

Regardless of the 32-bitness, it's always possible to overdrive the input of an audio interface or mixer's preamp with your input [device], i.e., whether a microphone or Hi-Z input for guitar/bass (especially if the latter has active pickups). If you're consistently doing that when setting the output where it needs to be, you'll probably want to change the default gain that's applied to that type of input. It's all in the manual.

 
Thank you for the answer, @keith.rogers

I use a MacBook Air with M2 and Logic Pro X (latest version for now).
Yes, it works correctly with 32 bit that was set in Project Settings, I tested the normalization of "cut" signal that I could restore.

I must clear that red light happens on Zoom device (red lamp) and it happens using the most loud and sensitive pickup on the guitar when playing on all strings with hard hits, this is a very rare situation.

Of course, I can reduce the gain on the guitar, but does it mean that the gain handle on the guitar needs to be repaired slightly?
 
If the recorded audio track is not clipped or distorted then I would suggest turning the guitar output down until that doesn’t happens. You could also try sending the guitar signal through a DI box that has a PAD switch and plug into the mic input (instead of the GUITAR/BASS one).

If you plan to use this setup a lot it’s probably worth experimenting with the gain setting for that input, i.e., lowering it with the control applet.
