Gain Reduction Metering
Unlike the metering on some processors, when any OPTIMOD-FM gain reduction
meter indicates full-scale (at its bottom), it means that its associated compressor has
run out of gain reduction range, that the circuitry is being overloaded, and that
various nastinesses are likely to commence.
Because the various compressors have 25 dB of gain reduction range, the meter
should never come close to 25 dB gain reduction if OPTIMOD-FM has been set up for
a sane amount of gain reduction under ordinary program conditions.
To accommodate the FM pre-emphasis curve, Band 5 of the Five-Band
Structure is capable of 30 dB of gain reduction.
Further, be aware of the different peak factors on voice and music — if voice and
music are peaked identically on a VU meter, voice may cause up to 10 dB more peak
gain reduction than does music! (A PPM will indicate relative peak levels much more
accurately.)
The AGC meter can be switched (within the Full Control screens) so that it either
reads the gain reduction of the Master (above-200 Hz) band, or the difference be-
tween the gain reduction in the Master and Bass bands.
The latter reading is useful for assessing the dynamic bass equalization
that the AGC produces and it helps you set the
AGC BASS COUPLING
control.
To Create or Save a User Preset
Once you have edited a preset, you can save it as a user preset. The 8500S can
store an indefinite number of user presets, limited only by available memory.
The 8500S will offer to save any edited, unsaved preset when the main screen is
visible. To save a preset:
A) Press the ESC button repeatedly until you see the main screen, which shows
the current time and the preset presently on air.
If there is an unsaved preset on air, the rightmost button will be labeled
S
AVE
P
RESET
.
B) Press the
S
AVE
P
RESET
button.
The Save Preset screen appears.
C) Choose a name for your preset.
