Enabling, Disabling and
Bypassing EQ Filters
You can enable, disable, or bypass specific EQ fil-
ters by clicking them.
To disable a filter:
 Start key-click (Windows) or Control-click
(Mac) the EQ Filter icon. When disabled, the
icon is black.
To re-enable a filter:
 Click the EQ filter icon. When enabled, the icon
is white.
To bypass a filter:
 Click the EQ filter icon a second time. When
bypassed, the icon is grey.
Using D2 in Stereo
Because Focusrite D2 has a single set of Filter pa-
rameter knobs, when it is used in stereo, you must
select which channel, left or right, you want to edit.
Use the Left Channel, Right Channel, and Link
buttons to do this. These controls only appear
when D2 is used in stereo.
Left Channel and Right Channel
Buttons
The Left Channel and Right Channel buttons are
used to select which channel is active for parame-
ter editing.
Selecting the Left Channel button activates the left
channel for editing. Any changes made to EQ pa-
rameters will affect the left channel of the stereo
signal.
Selecting the Right Channel button activates the
right channel for editing. Any changes made to EQ
parameters will affect the right channel of the ste-
reo signal.
Low-Pass Filter
If you are using all available bands of the 1–2
Band or 4–Band EQ and want to change fil-
ter types, you must disable one filter before
you can enable a different one.
