with full dynamic control. De-ess wide attenuates with whole frequency spectrum,
and although acceptable for most vocal sources, it may cause undesirable side
effects on a mixed program source (
refer to section 12.2; Broadband De-essing
and controls and 12.3; HF Only De-essing and Controls
). De-ess HF only
attenuates the high frequencies and therefore produces superior results in all cases,
which is essential when de-essing a mixed program source.
If simultaneous de-ess HF and compression are required, the separate channels
must be used for each function.

.3 De-essing Wide with Simultaneous Compression
Barrier strip linking B-C and D-G (as factory set).
Initial settings.
Set all compressor controls as required (
refer to section 14.1; Compression
). For
optimum de-essing effect, no more than 10-15dB of compression should be used. If
compression is not required, then set THRESHOLD to OUT.

Under program control, gradually rotate the DE-ESS THRESHOLD control
anticlockwise until the required effect is achieved. The FREQ control can also be
adjusted to ensure that frequencies lower than those causing concern do not
initiate de-essing. It should be remembered that this de-essing is wideband and
may cause distortion or pumping effects if the source program contains significant
low frequencies.
