Focusrite D2 and D3 Plug-ins Guide4

Chapter 3: Focusrite D2 5
chapter 3
Focusrite D2
Focusrite D2 is a high-quality digital equalizer
plug-in for Pro Tools. Developed in cooperation
with Focusrite, the D2 is based on the highly-ac-
claimed Red Range 2™dual EQ, designed by Ru-
pert Neve.
D2 features include:
Up to six simultaneous bands of EQ, includ-
ing: high-pass, low-shelf, low-mid peak, high-
mid peak, high-shelf, and low-pass filters
A highly accurate Cartesian graph that dis-
plays EQ curves in real-time as EQ parameters
are adjusted
Focusrite D2 Configurations
There are three configurations of the Focusrite
D2 plug-in, each designed to use a different
amount of your system’s DSP.
1–2 Band EQ
This module uses the least DSP. You can use up
to two filters simultaneously, depending on
which you enable. The high-pass, low-shelf, and
low-pass filters each utilize the entire module
and cannot be used in combination with an-
other filter. The low-mid peak, high-mid peak,
or high-shelf filters can be used in combination
with each other (up to two bands total).
4-Band EQ
This module uses more DSP. You can use up to
four filters simultaneously. Unlike the 1–2 Band
EQ, any combination of filters can be engaged,
up to a total of four bands.
6-Band EQ
This module uses the most DSP. You can use up
to six filters simultaneously. By default, the low-
pass and high-pass filters are in Bypass mode
when the 6-Band EQ is first opened.

D2 Parameters
Input Level
Input Level allows you to attenuate signal input
level to the D2. The range of this control is from
–18dBto+12dB.
When you use D2 in stereo, each channel has its
own separate Input Level knob. To adjust input
levels for both channels simultaneously, select
the Link button, then drag either knob.
Output Level
Output Level allows you to adjust the overall
output gain. The range of this control is from
–18 dB to +12 dB.
When you use the D2 plug-in in stereo, each
channel has its own separate output level knob.
To adjust output levels for both channels simul-
taneously, select the Link button.
Meters
The D2’s high-resolution plasma-style meters
indicate signal levels and detect clipping at the
input, algorithm, or output stage. When D2 is
used in stereo, two meters appear, one for each
channel.
A Clip Indicator is located above each meter. It
indicates clipping by increasing its brightness as
successive samples are clipped. Click the Clip In-
dicator to clear it. Alt-clicking (Windows) or Op-
tion-clicking (Mac) clears both channels when
D2 is used in stereo.
input Level
Output Level
Meters (Stereo mode)

Focusrite D2 and D3 Plug-ins Guide8
Metering:
• Green = nominal levels.
• Yellow = pre-clipping at –6 below full scale
signal.
• Red = full scale signal (clipping).
The Cartesian Graph
The Cartesian Graph displays a visual represen-
tation of the current EQ settings. As you adjust
the parameters of any currently active filter, the
Cartesian Graph will plot the changes to the EQ
curve in real-time. If you are using D2 in stereo,
the Cartesian Graph displays the EQ curve for
the right channel in red and the left channel in
blue.
EQ Filter Controls
Each of the six different EQ filters has its own
controls and its own icon. The icons act as three-
state switches for enabling, disabling, or bypass-
ing the specific filter. The current state of a filter
is indicated by its color:
• White = enabled. In this state the filter is
active, audible, and using available DSP re-
sources.
• Black = disabled. In this state the filter is
not using any DSP resources and has no ef-
fect on audio.
• Gray = bypassed. In this state the filter is
not active, but is still using available DSP
resources. The effect of the filter is not au-
dible.
High-Pass Filter
The 18 dB/octave High-Pass Filter provides a ro-
tary control for adjusting the corner (cutoff) fre-
quency, variable from 20 Hz to 6.4 kHz.
The Plug-in window includes a Clip LED
that lights red to indicate plug-in clipping.
The Plug-in Clip LED follows Pro Tools set-
tings for clip indication. (For more informa-
tion, see the Pro Tools Reference Guide.)
Cartesian Graph
Alt-clicking (Windows) or Option-clicking
(Mac) the Cartesian Graph resets all D2 pa-
rameters to their default settings. To reset
parameters for both channels when in Stereo
mode, Alt-Shift-click (Windows) or Option-
Shift-click (Mac) the Cartesian Graph.
High-Pass Filter

Chapter 3: Focusrite D2 9

The Low-Shelf Filter provides two rotary con-
trols: The upper rotary control adjusts the cor-
ner frequency, variable from 33 Hz to 460 Hz.
The lower rotary control adjusts the filter’s am-
plitude gain or attenuation. Amplitude range is
±15 dB from unity.
Low-Mid Peak Filter
The Low-Mid Peak Filter provides three rotary
controls. The upper rotary control adjusts the
center frequency, variable from 33 Hz to
6.4 kHz. The lower left rotary control adjusts the
filter’s amplitude gain or attenuation. Ampli-
tude range is ±15 dB from unity (utilizing a re-
ciprocal curve for both gain and attenuation).
The lower right rotary control adjusts filter “Q”
which is variable from 0.7 to 4.0.
High-Mid Peak Filter
The High-Mid Peak Filter provides three rotary
controls. The upper rotary control adjusts the
center frequency, variable from 120 Hz to
18 kHz. The lower left rotary control adjusts the
filter’s amplitude gain or attenuation. Ampli-
tude range is ±15 dB from unity (utilizing a re-
ciprocal curve for both gain and attenuation).

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 pa-
rameter editing.
Selecting the Left Channel button activates the
left channel for editing. Any changes made to
EQ parameters 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 stereo signal.
Low-Pass Filter
If you are using all available bands of the
1–2 Band or 4–Band EQ and want to
change filter types, you must disable one fil-
ter before you can enable a different one.
Left Channel, Right Channel, and Link buttons

rameters for both channels simultaneously. By
default, Link mode is enabled so that you can
easily maintain parity between the parameter
settings for both channels.
You can also use Link mode to help you main-
tain a relative offset between parameters settings
on the two channels.
Maintaining an offset:
1 Deselect the Link button.
2 Select the desired channel button, left or right,
and adjust the parameters for that channel.
3 Select Link mode and adjust the same param-
eters for the opposite channel. D2 will maintain
the relative offset between the parameter set-
tings for the two channels.
Alt-click (Windows) or Option-click (Mac)
while linking channels with offsets to copy
the parameters of the active channel to the
opposite channel (including input and out-
put levels).
