1.9 Channel Processing
1.9.1 EQ ..........................................................................................
The EQ section comprises four user-configurable parametric filters and a pair of swept High-pass and Low-pass filters.
The EQ is accessed by touching the on screen display to Assign the channel (the colour changes to gold) and then using the
controls on the right hand side of the screen.
When a control is adjusted the expanded view seen below appears in the input screen but this view can be seen at any time by
touching the EQ response graph on the screen.
Note - If the expanded view does not appear when a control is adjusted open the Options panel and set the
Auto Expand EQ option to Yes
Touching the normal EQ response graph will show an expanded view in a separate panel.
The order of EQ and Dynamics in the channel signal path can be changed using the worksurface button to the right of the
worksurface HPF and LPF controls.

4 Bands
Dynamic EQ
The type of filter used by the top and bottom bands can be changed by successive presses of the Curve button for that band.
The four parametric bands can be either Classic (Analogue style) or Precision (Digital style) type EQ.
Up to 8 Channels can have their EQ modules switched into Dynamic EQ mode by touching the red "Delta" symbol on any EQ band.
On any channel (Input or Output), open the EQ Module, and expand the dynamic controls. You can then switch on any (or all) or
the dynamic controls for that EQ Module.
Only 8 Channels can have their EQ Modules placed in Dynamic mode. An warning message will appear on screen if an attempt is
made to use Dynamic EQ on more than 8 channels.
See the SD Series Software Reference manual for more information on Dynamic EQ
