Digital headroom is permanently fixed at 0dBfs, regardless of bit depth. This is non-negotiable (until you get into floating math which is way over my head; but for OTB / real-world purposes, 0dBfs is the tops)
Pls correct me if I'm wrong but I always thought bit rate was describing digital headroom while dynamic range is a term in analogue and digital domains. Analogue headroom is purely determined by voltage. High voltage mixers like the RND 5060 or SSLs have high voltage rails= super high output and apparently a more dynamic and "large format console type" sound
***(quick pedantic aside: bit *rate* is something else entirely and not relevant to this discussion)***
Higher bit depth means lower quantization error noise, which translates to increased dynamic range. You could think of it as "footroom", in a sense.
Higher voltage in an analog system does indeed typically improve headroom. But I don't think it's accurate to say it's *purely* determined by voltage. There are plenty of things that can go wrong in an analog system to eat up or limit headroom!
FWIW, i don't think SSLs have particularly high voltage rails...i think it's like 18v or something? Maybe 24? There are people here who've forgotten volumes more than I know about this stuff, so surely someone can chime in there.
The RND stuff is wonderful. One studio I was on staff at had a 5088 and it was indeed a phenomenal sounding desk. On the other hand, the headroom of a console is NOT what defines its "LFC-type" sound. It's part of the equation, no doubt, but there are many excellent-sounding desks with much more 'pedestrian' voltage rails.
Hope that helps, and i especially hope one of our resident brainiacs will correct / expand on this post as necessary.
