Width
Smaller values have a narrower bandwidth, causing a tighter, more focused
de-essing effect. Higher values have wider bandwidth, for de-essing when un-
desirable frequency ranges are broader.
When Width is rotated fully clockwise, High Pass mode is activated. In High
Pass mode, Frequency
quency of the high pass filter (instead of the center frequency of the bandpass
filter). High Pass mode is useful when you want to attenuate all frequencies
above the cutoff frequency.
The available range is 0.15 (about 1/6 octave) to 1.61 (about 1 2/3 oc-
taves), plus High Pass mode.
Note:
Pass mode versus bandpass mode (unless UAD-2 DSP LoadLock is enabled).
Split
In normal use Split should be enabled, causing only the "ess" spectrum as de-
fined by Frequency and Width (i.e., the sidechain), to be attenuated. This pro-
vides the most precise de-essing control.
Split can be disabled, which causes the entire input signal to be attenuated
(instead of just the "ess" sidechain) which results in more traditional compres-
sion. However, the sidechain still controls attenuation when Split is off.
Click the Split button to change the mode. Alternately, you can click+hold the
LED area and drag like a slider to change the value.

UAD-2 DSP LoadLock is enabled).
