Filter settings page
• Filter type - available types are Notch, Low Pass (normal and peaking), High Pass (normal
and peaking), Hi Shelf and Lo shelf.
• Graph display - three modes are available, to ensure that clear information is available for
any application. “Curve” mode shows the overall response of the whole filter module.
“Active” mode shows just the response of the single filter currently being selected for
adjustment. “Individual” mode shows all the filters, but as individual curves rather than as
a single composite response.
Filter remove page
This page allows the currently selected filter to be deleted entirely (as opposed to bypassed - see
IN/OUT below). The centre encoder is turned clockwise to remove the filter, and then the right
encoder is also turned clockwise to confirm.
Turn the left encoder to select the type of filter required. The available options are Notch, Low-pass
(normal and peaking), High-pass (normal and peaking), Hi shelf and Lo shelf. Turn the right encoder
to confirm the selection and create the filter. There are four filters available to each channel, each of
which can be used across the whole frequency range from 20Hz to 20kHz.
6.5.3 Touchstrip operation with Filters
On the Filters page, the touchstrip can be used to select the currently active filter. If you are not
currently using the Freq/Level menu, the unit automatically switches to it when you press the
touchstrip. Press either the upper or lower part of the strip below the centre frequency of the
required filter. The centre frequency will highlight to indicate the selection. Once selected, the
frequency of the filter can be dragged up and down the display by pressing the strip and sliding the
point of contact to left and right. There is no difference between the upper and lower strips when in
Filter mode.
