Why are you turning your gains to 12 o'clock as opposed to setting them to a position where the channel meter is showing peaks around 0dB?
On the DDJ-RZ do the red LEDs at the top of the channel meters indicate that the signal is actually clipping internally or just that it's higher than expected? The master level meters are only ticking away at the bottom of the scale so the output DACs aren't being overdriven. I know most DAWs aren't going to clip internally even with signals overdriven pretty hard unless the final output is too hot, but not sure about rekordbox and the RZ.
I'm asking as a lot of the time with the gain knobs at 12 o'clock (which I'd expect to be the zero point) and auto-gain turned on the red lights are flashing.

Because in general 12 o'clock is a zero-gain position as with the EQ settings so with correctly auto-gain'd tracks there shouldn't be clipping if everything else is flat. Also, if I'm talking to a client or guest I can't really ignore them to tweak channel gains if there's a track which is running hot and the auto-gain hasn't correctly compensated.
Obviously on something like the SZ where the mixer is in external mode and the channel controls are actually processing the sound I'd not want to redline them. With the RZ playing purely from the computer in internal mix mode though I'd hope the software has enough headroom internally to not worry about clipping.
So, back to the original question but ignoring all the other factors, does the red light mean the channel is actually clipping in internal mix mode?

No - the 12 o'clock position is a zero point for the EQs, but not the trim / gain knobs.
And if you have set the peak gain prior to the song going "live," you wouldn't have to adjust it later during playback. That's part of cueing a track!
The products have approximately 19-21dB of overhead, so while you may not be "clipping" them, that's no excuse for poor gainstage management.
"My engine is fine until I hit the redline, right? So driving around at 6000RPM is fine!"
Except running a signal hot through software won't cause anything to overheat and blow up :)
I don't always have time during a gig to prelisten to a complete track to ensure there's no point it hits the red, especially when interacting with guests.
But 20db of headroom is pretty much ok. Unless anyone asks for a track with a ridiculous dynamic range hehe
