The amount of headroom between 0dB on the VU to digital 0dB is selectable from
- -15dB to -3 dB. There is no right value for this, it really depends on the
music, so just pick whatever value that causes the VU to spend most of it's time
between +/- 3dB.
(this stems from the fact that 0dB in the analogue world is the optimal level
whereas 0dB in the digital world is the maximum level)
You may want to increase the range of that reference level calibration,
particularly as it applies to anything having a semi peak reading
response.
-16dbFS = +4dbu is not an uncommon place to run, and -20 is another
common alignment.
