why the heck is my kick drum signal peaking, even when I have the gain turned all the way down?

Is it the individual channel peaking?  Is this a mic direct into the XLR input of a mono channel?  By "gain" do you mean the channel fader or the channel trim knob?

Since there is no mic/line switch, for each channel the XLR is pretty much dedicated for mic level inputs and the 1/4" TRS for any line level inputs.  Also, according to Behringer's block diagram, the mono channel peak indicators are actually after the gain trim, insert, low cut filter and EQ.  So there are a few things that could affect the level hitting the peak indicator.

Make sure to set your EQ flat, disengage any filters (low-cut/high-cut) and then see if it is still clipping the channel.  Look into buying an inline pad for the microphone.  
My guess is that the signal is just too hot for that channel strip to handle.  It could be the preamp (most likely) or you could be clipping the EQ stage...many things, but most likely the preamp, since it's the first thing that sees the signal.

I'm sure there are others out there, just take a look.

This happens on the mixers from which this design was "borrowed," too ... the Mackie 8-bus and small SR 4-bus mixers. Even with the input trim at minimum, there's still enough signal to indicate clip.

The simplest thing to do is to buy or make an adapter with XLR female on one end and 1/4" TRS on the other. Patch the XLR side into your snake and plug the 1/4" end into the channel line in. The line in has a 20 dB (or more, I dunno) pad in front of the preamp and that should prevent overloads.

Build a handful of these adapters as they are useful for kick, snare, and bass amp and keyboard line outs.
