21 CHOOSING THE PROCESSING CURVE (FM and ST)
21.1 INTRODUCTION
Once you have adjusted the input levels and reached the correct AGC level, you may move on to select the
processing curve.
The processor has 40 curves: the factory presets (PR) are stored in positions 01 through 30, while positions
31 to 40 may be set by the operator.
As shown in the table on the next page, there are 10 parameters involved in processing. Keep in mind that:
-
The letter ‘T’ in the last column indicates that the corresponding profile is useful for conducting Tests and
measurements on the processor
-
The letter ‘S’ indicates that the corresponding profile allows you to reach a high broadcasting sound level
(high density Signal) and an average sound fidelity
-
The letter ‘Q’ indicates that the corresponding profile should be used whenever you prefer a broadcast
with good fidelity (Quality)and an average sound level (low density).
Before creating a new custom curve, we recommend that you carefully evaluate the 30 factory
presets, all of which are suitable for immediate on-air use given their average content of the various signal
components.
You may compare the different curves if desired, using curve 1 (‘flat’) as a reference.
NOTE – Contrary to the submenu parameters, a new curve becomes operative (thus is broadcast)
only when it is selected via encoder and then confirmed by the ENTER command within 10 seconds
after selection.
21.2 HEAVILY SPOKEN PROGRAMS
The processor offers a group of profiles specifically developed for broadcasts that have heavy spoken or
vocal content in general. These profiles are characterized by low brilliance and high frequency values.
We also emphasize that, in the case of voice-only broadcasts, it is recommended to lower the operating level
of the Stereo Enhancer (Effect Level).
The best factory-preset curves suited to voice processing are numbers 26 through 30.
Make also sure the Voice Optimizer stage is set as enabled (ref to par. 19.4).
21.3 HEAVILY MUSICAL PROGRAMS
The preset curves 1 through 25 are specifically designed for processing music programs.
By default, the curve presented by the processor upon start-up is number 18 (also indicated as ‘RIO’).
This is one of the most widely used curves, since it offers a good degree of density and listenability. Of
course, the choice of curve depends strictly on the type of musical programming, as well as personal taste or
preference. You should also keep in mind that the final ‘timbre’ may also be affected by other equipment in
the transmission chain.
