[ 9 dBu to +13 dBu (VU), or –1 to +21 dBu (PPM)] in 0.5 dB steps
The reference level VU and PPM (Peak) settings track each other with an offset
of 8 dB. This compensates for the typical indications with program material of a
VU meter versus the higher indications on a PPM.
This step sets the center of the 5500's gain reduction range to the level to which
your studio operators peak their program material on the studio meters. This as-
sures that the 5500's processing presets will operate in their preferred range.
You may adjust this level with a standard reference/line-up level tone from your
studio or with program material.
Note that in this step, you are calibrating to the normal indication of the studio
meters; this is quite different from the actual peak level.
If you know the reference VU or PPM level that will be presented to the 5500, set
the reference level to this level, but please verify it with the steps shown directly
below.

console at normal program levels (typically 0VU if your console uses VU
meters).
