This is one of those terms that I’ve always felt I understand what it means, however, I can’t define it. Even though this is a little embarrassing I’d love to know the actual technical definition when equated with audio gear.
In another thread I said the following about mic pres
“I am not sure if people classify pres that are clean until they hit breaking point high headroom or if they call pres that gently compress with subtle distortion until they finally distort in an awesome and glorious way high headroom? I am not sure if high headroom pres are ones that you can crank 50 db with little noise floor”
When people say SSL or RND consoles have high head room summing sections I think they mean that you can send them a lot of signal until they start to audibly distort. Then again they say that they can hear an SSL 4000 distort in a pleasing way so does this mean they have low headroom because you hear the distortion, even if it sounds good?!?
Not sure. If the SSL 4000 has loads of head room than all compressors have even more head room:)
