reducing the sibilants themselves.
For the most transparent processing and general purpose use, we suggest split
band as the first choice, together with AIR.

LINKED OPERATION
User convenience usually dictates that stereo operation is via Channel 1, so that
only one set of controls have to be adjusted. This is particularly true of
compressors, where image shifting is to be avoided. In the case of the MX50
however, this would restrict the units stereo potential, so both channels must be
adjusted separately. The reason for this is the nature of stereo material. High
frequencies are more likely to occupy the full stereo image because they are
present for less time and have less effect on the stereo image, so high frequency
activity on, say the left channel may not be present on the right, so it would be
unwise to attenuate the right channel in response to a signal on the left.
Each De-esser channel has a floating threshold, which is based on the full band
signal level of that channel. These internal signals are linked to produce a mono
signal level which is used to control the thresholds of both channels. The result is
that sibilants are limited to the stereo level rather than the individual channel level.
The benefit of individual channel operation is when sibilant frequencies are
different on each channel. In these cases, the individual channel frequency as well
as the other parameters can be adjusted to suit that channel. Of course, abuse of
this freedom can cause image shifting, so we would suggest that the two channels
are set similarly, unless special effects are being created.
