SOUND PROCESS
9.1.
Overview
The 5-band sound processor is a cost option. Without the license, available features are limited.
The Ecreso FM features an integrated 5-band sound processor. This fully digital sound processor offers a unique signal
quality and outstanding reliability as no additional hardware is required.
All processing calculations are performed by the direct to channel digital modulator, from audio to RF signal.
Here is a block diagram of the processor:

Presets
There are two types of factory presets:
-
WB presets (wide band)
-
5B presets (five bands) - only available with the Sound processing option)
Unlike many processors, there is no ‘bypass’ preset, but a real bypass parameter (see parameter description below).
The presets WB PROTECT and 5B FINALIZE are dedicated to protect your broadcasting chain against over-deviation
without audible distortion.
All other presets can be used as unique processor or secondary processor in your chain. Don’t hesitate to try several
presets from the list without taking their name as a main criteria choice. Those are only very general indications.
Depending on your format, your expectations and the other radios available in your area, the best preset for you can
be any of those. As soon as you identify a preferred preset, feel free to you use it as is, or fine tune a few parameters
to better match your needs (see next sections)
