Is Mesa D-800+ fixed HPF after the effects loop?

I suppose this is a question best answered by Andy @agedhorse but if anyone knows the scoop, I'd appreciate it.

Is there any high pass filtering on the 800+ power amp if you plug in an external pre via the effect loop? I checked out the block diagram in the manual and it's clear the adjustable HPF is before the insertion point. Just wanted to confirm where the fixed HPF is. You know, before I destroy more speakers.

Thanks y'all

Not really, the assumption is that any preamp you would use would have whatever HPF was deemed appropriate.

Thank you!
