Acuma DSR-1 De-Esser
Introduction
Thank you for purchasing the DSR-1 (De-esser) from Acuma
Labs. One of the exciting members of the new family of 24-bit
plug-ins for the D8B, the DSR-1 has been specifically designed
for the Mackie Universal Effects (UFX) card.
The DSR-1 plug-in for the Mackie D8B is a highly accurate,
frequency controlled, three-band dynamics processor. It enables
you to quickly isolate and correct unwanted sibilance in vocal
recordings of singers and speakers. The DSR-1 reduces
annoying sibilant and popping sounds that are often found in
recordings without losing the crisp top-end clarity. Don’t let the
simple chicken-head controls and the funky retro-look fool you.
The DSR-1 is a highly professional tool that is ideal for editing
vocals, instrumentals, and other sources. The DSR-1 is an
invaluable plug-in for your D8B that can save a great recording
by removing troublesome frequencies.

About the D8B UFX Card
The Mackie UFX card provides robust processing power for
computation-heavy plug-ins. The UFX card is a 4-in/4-out
architecture, which means that it supports four mono plug-ins or
two mono and one stereo, or two stereo plug-ins simultaneously.
Up to four UFX cards can be installed in the D8B, allowing up to
sixteen simultaneous single-channel effects, eight stereo plug-
ins, or combinations there of.
About the DSR-1 (De-esser)
The DSR-1 employs mid- or high-frequency compression. The
frequency and bandwidth controls are used to isolate the
problematic frequency range. No external keying device is
required. The ess band Key Listen feature allows you to solo (or
listen) to the isolated frequency range. The DSR-1 can also help
to compress shrill, high-pitched sounds that may accompany
acoustic instruments. The DSR-1 includes a high-pass filter that
helps you to clean up other artifacts such as microphone pops.
The DSR-1 includes a series of great male and female vocal,
instrument, and spoken word presets that can make the
toughest job easy to correct. As with all D8B plug-ins, all of
DSR-1’s parameters are automatable, and can be saved as user
presets.
Note: Earlier D8Bs were fitted with 16 MB of memory. It is recommended that
you increase this to 32 MB (as fitted in newer D8Bs) if you install more than one
UFX card. Memory upgrade instructions are supplied with each UFX card.

Using the DSR-1
Front Panel Overview
You can think of the DSR-1 as being broken into five basic areas:
the status block, global block, I/O block, controls, and meters.
DSR-1 Block break down overview
Status Block (See page 8)
The status block includes the PRESET up/down toggle buttons,
Preset Title window, and SOURCE (input select).
Global Controls Block (See page 9)
The global controls include: ess band (key) LISTEN, Mem A and
B select buttons, MENU, WRITE, ENABLE, HELP, and minimize
buttons.
I/O Levels Block (See page 11)
The I/O block is comprised of the input (IN) and output (OUT)
meters and the INPUT level adjustment ranging from off to
+12 dB.
Controls Block (See page 12)
The controls block is the heart of DSR-1. It includes the high-pass
FILTER, as well as FREQuency and bandWIDTH control for
selecting the ess band (ess range 1k to 20k). The controls block
also includes the THRESHold control (–49 dB to 0 dB), and the
RATIO control (1:1 to 100:1).
8
Acuma DSR-1 De-Esser
Meters (See page 14)
There are separate meters to indicate the ess-band level and the
ess-band gain reduction amount.
The Status Block
DSR-1 Status Block
Preset Toggle Buttons
The PRESET up/down arrows, located just to the left of the
preset window, enable you to scroll up or down through either
the factory or user presets.
Tip: In most vocal recordings, there are usually a number
of areas that could be improved with the DSR-1. However,
there is not necessarily one overall optimum setting that
will work throughout the track. Building user presets is a
good way to have multiple De-esser settings that can be
quickly accessed. You can then apply these settings to
various regions of your track. There is no delay time in
loading presets. You might try building performances by
stacking user presets and toggling between them using
the up/down arrows. These are located at the left side of
the preset window. You could also insert a load preset
event in the mix editor.
For example, you can quickly switch from a Verse Ess to
Chorus Ess preset and back. This would eliminate
problematic spots in your recording. Additionally,
pressing the WRITE button automates your changes as
part of the D8B session.
Note: See the section on the WRITE button for more information on how this
works. The user preset list sorts alphabetically. If you want your user presets
to come up in a certain order, use letters at the beginning of the preset names.
(I.e. Aesss, Besss, Cesss, etc.).

PRESET Title Window
The PRESET Title window is located at the top of the control
bar. It displays the currently selected preset corresponding to
the existing DSR-1 settings. Click on the window to access the
pull-down menu where you choose between factory or user
presets.
Note: It is possible to save presets to the User Preset folder, which is the
default folder, or a folder of your own making. The user presets point to
the last folder you’ve saved or recalled presets from.
SOURCE
The input select is located directly to the right of the PRESET
Title window. Use your mouse to select from pre/post insert,
auxiliary, or master insert inputs. In general, the DSR-1 is
intended to be used as a channel insert.
Global Controls Block
DSR-1 Global Controls Block
LISTEN
The LISTEN button acts like a solo that lets you hear (solo) the
frequency band set with the FREQ and WIDTH pots in the
Controls block. Selecting LISTEN isolates (or solos) this range.
This should help you zero in on annoying sibilance by using your
ears to identify where the problem is occurring.
Memory A/Memory B
The Mem A and Mem B buttons temporarily store DSR-1
settings to allow comparative referencing. You can also copy and
paste settings from one memory location to another.

Acuma DSR-1 De-Esser
MENU
Pressing the MENU button opens a pull-down menu. This menu
performs familiar functions such as load, save as, cut, copy, and
paste. It also displays the plug-in’s build number and version.
WRITE
WRITE enables the D8B’s automation so all the changes you
make in the DSR-1 plug-in are recorded as part of the D8B
session. This works similarly to a channel’s write button. To
record automation for a plug-in, ALL must be turned on in the
automation section of the D8B. Automation must also be out of
Bypass. Plug-in parameter edits are recorded when the D8B is
recording, but only if the plug-in’s WRITE button is on, or if
Auto Touch is turned on. Auto Touch is located in the
automation section. When you press stop, the plug-in’s WRITE
button turns off.
ENABLE
The ENABLE button either enables or bypasses the DSR-1.
Help Screen (?)
Pressing the help screen (?) button brings up a quick-start
screen to quickly get you using the plug-in. It’s also useful for
quick reference.
The Help Screen
Minimize Button (X)
The minimize button (X) in the top-right corner hides the screen.
However, the screen is still active until it is disabled in the D8B
Plug-ins window.
