“Smooth” - Adjusts the peakiness of the noise profile.
“Tune” – In some situations can help to remove musical noise.
“Auto” Mode - Enables automatic updating of noise profile and the noise profile level relative
to the input signal.
“Freeze” Mode – Once you have obtained a good profile, this button will freeze the profile to
prevent it updating.
“Manual” Mode – In this mode, the profile is forced flat to represent white noise. You can then
use the “Colour”, “Air” and bias controls to modify the shape of the profile.
“Colour” – Modifies the LF shape of the noise profile.
“Air” – Modifies the HF shape of the noise profile.
Description of Controls – DeNoiser Removal Section
“Reduction” – sets the amount of attenuation of broadband noise components below the
threshold.
“HF Cut” – This is a simple low-pass filter with a fixed -18dB attenuation. It is active when the
DeNoiser Enable and Master Enable are both active.
“Makeup” – Provides a way to adjust the level of the de-noised signal to compensate for any
loss in level due to the de-noising process. This makes it easier to perform with and without de-
noising comparisons using the master IN button.
“Enable” – If Master Enable is also IN, this makes the broadband DeNoiser active using
glitchless switching.

“Bias Select” – This toggles between the red bias curve that modifies the shape of the noise
threshold profile, and the yellow bias curve that modifies the shape of the noise reduction.
