OPTIMOD-AM DIGITAL OPERATION
3-17
Compressor attack times and thresholds are available. These controls can be exceed-
ingly dangerous in inexperienced hands, leading you to create presets that sound
great on some program material and fall apart embarrassingly on other material.
We therefore recommend that you create custom presets at the Advanced Modify
level only if you are experienced with on-air sound design, and if you are willing to
take the time to double-check your work on many different types of program mate-
rial.
The PC Remote software organizes its controls in tabbed screens. The AGC, AM
E
QUALIZATION, HD EQUALIZATION, STEREO ENHANCER, and LESS-MORE tabs access the Ba-
sic Modify controls. The remaining tabs combine the Full Modify and Advanced
Modify controls, logically organized by functionality.
See the note on page 3-16 regarding the unavailability of L
ESS-MORE after you have
edited a control in Full Modify or Advanced Modify.
Gain Reduction Metering
Unlike the metering on some processors, when any OPTIMOD-AM 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-AM has been set up
for a sane amount of gain reduction under ordinary program conditions.
To accommodate the boosts introduced by the HF EQ control, 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.)
To Create or Save a User Preset
Once you have edited a preset, you can save it as a user preset. The 9400 can
store an indefinite number of user presets, limited only by available memory.
The 9400 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 PRESET.
B) Press the S
AVE PRESET button.
The Save Preset screen appears.
