De-Esser
A de-esser is a form of compressor, which is only reactive to the frequencies associated with the pronunciation of the letter “s” (“ess”). It is necessary to perform this function on over-modulated signals in the “s” frequency range and is adjustable from 1,000 Hz to 10,000 Hz. This occurs due to poor mike technique, a poor initial mix, improper mic channel equalization, or insufficient “padding” of the mic input circuit during the recording session. When the frequencies in the sensitive band are detected and are above the threshold setting, compression will be applied to the degree determined by the compressor ratio control. To place the compressor in the De-esser mode, click on the box by the same name.
One global control is provided in addition to all of those mentioned above. The output gain allows you to correct for overall amplitude effects (attenuation or gain) that any of the dynamic processor functions may have on the overall output signal level. Presets have also been provided to get you started with reasonable setup parameters for the various dynamic processor functions.
The Dynamics Processor includes an automatic level control feature (ALC). Sometimes, these algorithms or systems are referred to as automatic gain controls or AGC’s. This feature provides upward expansion of signals below the threshold line and downward compression of signals above the same threshold. This feature is useful in Forensics applications where there is a large variation in signal levels between several different parties that may be communicating with one another. It is also useful for the broadcast of live sporting events (if you have the DC Forensics10 version of the product) in which the crowd reaction is of interest when the announcer is not speaking. Simply clicking on the “ALC” box in the Dynamics Processor activates this feature. The threshold, attack, and release controls are still active when this function is invoked.
Output Control and Clip LED
Since the Dynamics Processor can add considerable gain to your system (especially when operating in Expander mode), an output level control and a red LED clip indicator are provided. If you observe that the red LED indicator is flashing, then the system is clipping your signal. For the cleanest results, use the Output Control to decrease the level until this no longer occurs.
