3. Module Library
The DM8000 DSP is equipped with comprehensive library of processing modules
that can be deployed and congured by using the DM8000 DSP Designer
software. You can build the entire processing structure and signal routing using
the DM8000 DSP Designer software, and then compile the conguration and run
it in the DM8000 DSP.
To deploy a specic module, click on that module’s graphic icon in the Module
Library screen, and then drag the module into the Build Window. Alternately, you
can also use the Module Library Toolbar to access all of the DM8000 modules.
Once a module is placed into the Build Window, the module “unzips” and the
Component Objects contained in the Module appear on screen. All available
settings can then be accessed by right-clicking over the desired Component
Object. Right-clicking launches a Control Dialog Box, which displays the
component controls in a more conventional user interface where you can
program settings and make other adjustments.
3.1 Input Output Modules
DM8000 Module Component Objects
Once deployed in the Build Window, the DM8000 module unfolds into three
Component Objects:

• DM8000 Output 6 Channel
• UltraNet Out
These Component Objec ts can be moved and placed separately where needed.
DM8000 Input 10 Channel
The DM8000 Input 10 Channel component object routes analog audio signals
from the 10 analog inputs on the DM8000 rear panel into the DSP for processing.
Analog audio inputs that are equipped with Acoustic Echo Cancellation (AEC)
appear with a light orange color.
To open the Input Output Module Library, click on the Input Output tab in

• Gain adjusts the amount of cut or boost applied at the center frequency for
the current band.
• Active Band and Gain may also be adjusted by dragging the band controls
shown inside the graph. The selected band control becomes yellow, and
dragging it up or down aects Gain for that band.
• Flatten Band and Flatten All changes the band Gain to “0” (at).
• Bypass Band and Bypass All disable the band(s) without
changing settings.
• Drag Points turns the band controls on or o, revealing the resultant
curve only.
• Flatten Band and Flatten All changes the band Gain to “0” (at).
• Bypass Band and Bypass All disables bands without changing settings.

3.3.3 Feedback Suppressor
Feedback Suppressor behaves like automatic cut-only Parametric Equaliser
module. Parametric equalisers utilize automatically-assignable bands of
equalization which detect and remove feedback frequencies.

3.4 Filters
Filter modules provide High Pass, Low Pass, High Shelf, Low Shelf and
All-Pass lters for applications that require rolling o of frequencies, simple tone
controls, or phase compensation.
Filters may be connected between any components within the Build Window.

Feedback Suppressor Dialog Box
• Active Band selects the current band for which settings will be displayed.
• Center Freq. displays the center frequency for the current band.
• Gain displays the amount of cut applied at the center frequency for the
current band.
• Bandwidth displays the range of frequencies, above and below the center
frequency, which are also aected by the current band. Float Limits restricts
all oating bands to a selec ted maximum depth (cut) and bandwidth
(Narrow = 1/40-octave; Wide = 1/10-octave).
• Reset All temporarily returns the gain of all oating bands to 0dB (at).
• Fix Band and Fix All frees frequency bands to become manually adjustable
(non -oating).
• Bypass Band and Bypass All disable frequency band without
changing settings.
• Drag Points turns the band controls on or o, revealing the resultant curve
only. Band highlights the current band inside the graph.
NOTE: Feedback Suppressor modules use a hefty amount of processing power
and are limited to a maximum of six teen bands, although, in practice the number
of bands actually in use will often be fewer. The Feedback Suppressor’s active
bands can also be recreated within a Parametric Equalizer to save DSP resources.
High Pass Di alog Box
• Filter Slope selects the lter type (Linkwitz-Riley or Butterworth) and slope
of the lter.
• Cuto Freq. selects the cuto frequency for the lter. Cuto Freq. may also
be adjusted by dragging the cursor shown inside the graph.
• Bypass turns the lter on or o.
