your system beyond those provided with QUICK SETUP, then you may need the addi-
tional information in the sections below. However, for most users, this material is
only for reference because QUICK SETUP has enabled them to set up the 8500S cor-
rectly.
For the following adjustments, use the appropriately labeled soft button to choose
the parameter to be adjusted. To change a parameter (like an output level), it is usu-
ally necessary to hold down the soft button while turning the knob.
1. Temporarily set the external AGC mode to "No."

3. Adjust Analog Input Reference Level.
−
[ 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 7 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 8500S'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 8500S'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 8500S,
set the reference level to this level, but please verify it with the steps shown di-
rectly below.
A) Press the Recall button.
B) Turn the knob until ROCK-MEDIUM appears in the lower line of the display.
