EXTH sets the threshold at which the expander starts to work.
EXG sets the amount of negative gain.
EXSL controls the slope of the expander circuit.

Dither is a low-level pseudo-random signal which is added to digital audio to
reduce quantization noise, in effect, by replacing it with a "nicer sounding" noise.
It is possible to filter the quantization noise in such a way that almost all of the
noise within the frequency range where human hearing is most acute is shifted
to higher frequencies. This is called psychoacoustically optimized noise shaping
(PONS) because it takes advantage of the variations in the ear's sensitivity to
noise within the 20 Hz - 20 kHz range.

DITH allows you to vary the amount of dither gain added to the signal.
This control allows you to turn the dither function on or off.
