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 a

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. Note: Earlier D8Bs were fitted with 16 MB of memory. It is recommended tha

Let’s Get Started Requirements • One or more Mackie UFX cards • Mackie Real Time OS 3.0 Software • Plug-in Software We will assume you have successfully installed a Mackie UFX card and Mackie Real Time OS 3.0 software upgrade. If you have encountered problems with the installation of hardware or software, please see their associated user guides or contact Mackie support (www.mackie.com). Please see the Licensing section of the Digital 8•Bus version 3.0 owner’s manual for information on both auth

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

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 w

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 sele

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 o

I/O Levels DSR-1 I/O Levels IN/OUT The input and output meters are located at the far-left side. These meters represent the incoming signal and the output (post effect) signal. OL OL (overload) is represented by the two small boxes above the in/out meters. The left-most overload indicator is for input level, and the other one is for output. They flash red if overload is occurring. INPUT The INPUT knob determines the gain or attenuation that is applied to the input signal. 11 User’s Guide

Controls Block DSR-1 Controls Block Note: Only the signal in the band selected by the FREQ and WIDTH con- trols are affected by the DSR-1. Signal outside of this range, both above and below in frequency, is unaffected. FILTER The FILTER knob controls a high-pass filter ranging from 20Hz to 200Hz. It offers you a quick and convenient way to reduce low-frequency noise. The high-pass filter can be very useful in eliminating unwanted artifacts such as microphone pops.

FREQ and WIDTH pots so you hear as much of the problematic sibilance as possible. At the same time, minimize the amount coming through of the signal you wish to leave unaffected. Typically, you will find a center frequency in the range of 3k to 6k, with a width ranging from 20 to 40 is useful. Watch the key level change as you adjust to the frequencies of the ess range. Now adjust the DSR-1’s threshold level using the threshold pot. The threshold level is also portrayed as the small horizontal b

RATIO The RATIO select is set to usual compressor increments that range from 1:1 to 100:1. Simply turn the pot to set a desired ratio. For example, 3:1 means that if a signal is 3 dB over the threshold, it will be reduced in amplitude to 1 dB over the set threshold. See “A Closer Look” on page 12 for further information. Note: The GAIN meter displays gain reduction. The LED moves downward from the top of the meter starting at 0 dB and indicates negative dB, or gain reduction. Meters (S-BAND and

DSR-1 Factory Presets The following table is a simple guideline to help you understand the factory presets, and what settings were applied to the individual presets. Don't be afraid to run anything through the plug-in preset, though. Then customize the parameters to your specific needs, and save it as a user preset. So get creative and have fun!
