6.3 Input EQ
The Controller has three types of input EQ: Parametric EQ, Band Level EQ and Graphic EQ. Additional
Parametric output EQ is available on the XOVER page and Aux tabs. This section deals with input EQ.
Groups and Modules can have multiple layers of EQ, called EQ overlays. Each Module can have up to eight
EQ overlays, and each Group can have up to four EQ overlays. A Module can have up to 256 input EQ lters
distributed amongst these EQ overlays. The large number of lters is necessary in order to allow for sophis-
ticated Grouping of Graphic EQ overlays. Input EQ Overlays can be stored and recalled from a le.
A Module’s overall input EQ response is calculated by combining its input EQ overlays with those of all
Groups to which that Module is assigned. The resulting composite EQ curve is indicated by a white line that
is displayed on all overlays. A grey line, if visible separate from the white line, indicates the EQ response
curve for the selected overlay only; refer to section 6.4.6.4 on page 100for instruction on enabling/disabling
this feature.

6. 3.1 Default Overlays
Modules and Groups both use the same EQ overlays and EQ functions. If a Module is assigned to a Group,
the Group EQ overlays can be viewed from the Module but cannot be updated. Changes to Group EQ are
performed by accessing the Group’s controls.
By default, a Module has Parametric EQ (PEQ1) and Band Level EQ (BLEQ2); a Group has a single Paramet-
ric EQ (PEQ1). A small gray dot to the bottom right of these EQ OVERLAY LABELs signies they are default
overlays that cannot be removed.
