M500 OPERATORS MANUAL Ch 4 - 5
It is necessary to set up the filter via the FILTER key and menu so that only the most sibilant
sounds are passed. This is best done by monitoring the filter output while the offending signal
is present and then tuning the filter so that it captures as much as possible of the sibilant sound
and as little as possible of the rest of the material.
Back on the DE-ESS page, the parameters can be set up in a similar way to setting up the
COMPRESSOR. It is important to set the threshold value carefully while monitoring the processed
signal as over-processing can cause noticeable dips or dulling in the sound. As with the
COMPRESSOR, both NORMAL (ratio) and SOFT (soft-knee) modes are available, SOFT generally
being least obtrusive but NORMAL being more positive in difficult situations.
Most regular jobs can be tackled with the basic DE-ESSER but more complex DE-ESSing systems
are available amongst the advanced features in later menu pages. The other options are: Single-
band De-ess, Two-band Compression and Two-band Complex Compression. These more complex
systems require both audio channels in order to function, though the basic Full-band de-esser
may be assigned as a dual-channel Effect.
For a more detailed discussion of the more advanced parameters, refer to the DE-ESS advanced
section of the manual.
