Coda no.8 Vu metres question

I used to have a #8 with meters and I reached out to Coda with this very question.
 

Their response and my questions below:

Red zone does not mean danger.  The switch sets the 0 dB point to 5 or 
300 Watts as indicated on the front.  At low levels the difference may 
be minimal on efficient speakers.

@zlone i see, so the first setting with the meters moving very little is the 300 watts operation obviously and the second with the meters swinging is the 5 watts operation I'm assuming. Ok that clears it up actually, thanks. Something I should think could be put in the manual. 

I agree. It would save some time to have it in the manual. Great amp though! What preamp are you using in front of it?

@zlone yes, great amp, I agree. Currently I'm using a Plinius M16. Quite content with this combo.
