Why must I leave this wonderful newsgroup to read an article on a web
page just to find out what your question or comment is about?

Do you have a question? If so, here's the answer:

With digital recording, you, and nobody else (unless there's no knob)
decides how much headroom you want. You make that headroom by adjusting
the input gain of the A/D converter device so that with your nominal
analog level going in (say +4 dBu), the meter reads downscale by the
number of dB of headroom that you want (say -20).

Two things:

1. If there's no input level control, you're stuck with whatever you get

2. You can't make headroom that isn't there. If the maximum output level
of your source, say a mic preamp, is, say +18 dBu, the best you can do
is set the input level control so that your maximum output level reads 0
dBFS and forget about a "standard" operating level (+4 dBu).

And a third thing: Don't let those Brits confuse you. If you don't use
PPMs, stick to a meter scale that you sort of understand. And remember,
"0 VU" can be any level you want, but
"+4 dBu" is the same the world around.
