     ||||  ® Section 2: The DDP Tour Signal Flow The following simple illustrations show how audio signal flows through the DDP, and how the LCD display works. They will help you to understand where the DDP’s metering points are located, as well as identify the var- ious elements of the LCD display.

  • Page 7: Software

       yyyyy zzzz |||| Digital Dynamics Processor Section 2: The DDP Tour SOFTWARE The DDP software works on a “building-block” philosophy. Every program number consists of a processing “setup” which is built from processing elements that make up a “chain”. The chain elements may be used in dif- ferent combinations to produce a desired effect.

       yyyyy zzzz |||| Digital Dynamics Processor Section 3: Setup / Basic Operation MIDI CONNECTIONS The DDP has a full complement of MIDI functionality. The MIDI connectors on the Rear Panel are configured in the traditional way: with an “In” jack and an “Out/Thru” jack. The DDP can be used in common MIDI systems at any point in the MIDI chain.

     ||||  ® Section 3: Setup / Basic Operation SOFTWARE NAVIGATION hreshold Metering On every program, you will find threshold metering for each element of the processing setup. These take the same form as the now-standard dbx 10 Series processors’ threshold meters: a plus (+) or minus (-) sign in a square box.

     ||||  ® Section 3: Setup / Basic Operation 2. Press the “CH 1” or “CH 2” button, (depending on which setup you want to look at) while the “pro- gram” button’s light is on. This method only lets you see the setup for one channel at a time. The con- tents of the setup, or the setup’s chain, will be displayed in the third line of text.
  • Page 13    yyyyy zzzz |||| Digital Dynamics Processor Section 3: Setup / Basic Operation There are three different linked chain sequences built in to the DDP. From these sequences you can build your own unique chains in order to fit your needs. They are listed below. LINKED chains The following chain types are available in any Linked Setups: Chain Type 1:...
  • Page 14  ||||  ® Section 3: Setup / Basic Operation There are also six different mono chains available to any dual mono program on the DDP. Three have in-line 3- band parametric EQ and three have sidechain EQ. They are as follows: MONO chains The following chain types are available in any mono Setups: Chain Type 1:...

     ||||  ® Section 4: Editing / Saving / Recalling Programs THE STORE BUTTON Whenever a parameter has been changed, the Store button will light, prompting you that there have been changes made to the setup. If you want to keep the changes, you must store the new setup. You may choose to rename and save the setup in the setup library.

  • Page 17: Editing Compressors

       yyyyy zzzz |||| Digital Dynamics Processor Section 4: Editing / Saving / Recalling Programs Attack control from 0.1ms to 200ms: As the signal reaches the threshold area, the Attack control sets the speed at which the gate opens. Use very fast attack times to catch the fronts of transient signals. Hold from 0ms to 500ms: The Hold control sets the amount of time the gate is held open after the signal passes below the threshold point.
  • Page 18  ||||  ® Section 4: Editing / Saving / Recalling Programs Auto mode off/on: Activating Auto mode disables the Attack, Hold and Release controls, triggering a message to that effect in the curve window. Attack and release settings become fully program-dependent, and manual changes in the settings do not have any effect on the audio signal or the response of the compressor.

  • Page 19: Editing Limiters

       yyyyy zzzz |||| Digital Dynamics Processor Section 4: Editing / Saving / Recalling Programs EDITING LIMITERS Parameters of the Limiter The parameters included on the DDP for limiting operations are as follows: Limiter output level Limiter threshold Figure 17: Limiter parameters and curve Off/on: Again, the limiter must be turned on to be able to change the parameters and affect the signal.

  • Page 20: Editing De-Essers

     ||||  ® Section 4: Editing / Saving / Recalling Programs EDITING DE-ESSERS Parameters of the De-Esser The parameters included on the DDP for De-Essing operations are as follows: Frequency at which de-essing begins to occur Figure 18: De-Esser parameters and curve Off/on: Same thing as all the others.

  • Page 21: More About Sidechain Eq

       yyyyy zzzz |||| Digital Dynamics Processor Section 4: Editing / Saving / Recalling Programs Bands 1, 2, and 3: The EQ is a three band parametric which allows adjustments of frequency center, Q, and level. Frequency Center from 25Hz to 20kHz: You can choose a center frequency from 25Hz to 20kHz all all three bands of the EQ.

  • Page 22: Changing Chain Types

     ||||  ® Section 4: Editing / Saving / Recalling Programs The sidechain path may also be used to reduce the effects of low frequencies on the compressor. Using the EQ to de-emphasize low frequencies allows the detectors of the gate, compressor, and limiter elements to react only to the more musical parts of the audio signal.

  • Page 23: Saving A Setup

       yyyyy zzzz |||| Digital Dynamics Processor Section 4: Editing / Saving / Recalling Programs 4. When you have named the new program, press store again. the screen bumps to the next save screen, asking you to select a program for the DDP to erase and write the new program over. Note that you can only access programs 1-50 in this screen, as that is the only area where you can write new pro- grams over old ones.
  • Page 24  ||||  ® Section 4: Editing / Saving / Recalling Programs Store New: 1. To store a new setup, choose Store New after pressing the store button. Again, you must name your new setup. After you are done, press Store once again. You now must choose a place for the new setup to be placed in the setup library.

       yyyyy zzzz |||| Digital Dynamics Processor Section 5: Utility Functions UTILITIES The Utilities menu is accessed at any time, via the Utility button. The utilities menu is the same as the other menus of the DDP. Once in the utility area, the LED will light on the Utility button, indicating the selection. Different menu selections are shown in the three lines of text below the program number.

  • Page 26: Digital Output Mode

     ||||  ® Section 5: Utility Functions Output Mode This is where you will select the digital output mode of the DDP. If you have the optional Digital I/O card installed in your DDP, this page refers to setting the output format of the optional card. You can set the input and output independently to either AES/EBU or S/PDIF formats.

       yyyyy zzzz |||| Digital Dynamics Processor Section 6: Appendices APPENDIX 1: MISC. INFORMATION Hard Reset From time to time you may encounter a situation which locks up the DDP’s software. Usually this is due to opera- tor error. Which means you asked the DDP to do something we did not anticipate in the implementation of the software, or something else has locked up the DDP.

  • Page 28: Tcm™ Transient Capture Mode

     ||||  ® Section 6: Appendices TCM™ -- Transient Capture Mode Transient Capture Mode™, or TCM™ works on the principle of delaying the audio signal up to 30µs, and letting an unheard “control” signal begin to activate the response of the VCA. The overall result is the perception of a very fast moving compressor, able to catch the front of almost any transient signal, but not delaying the audio signal enough to produce any phase correlation errors.
