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. You are now in “setup” mode. This method lets you see the setup for one
channel at a time. The contents of the setup type will be displayed in the third line of text. As you
press the CH1 or CH2 button, the program LED will go off, and the LED on the button you pressed
will light, indicating that you are now looking at channel one’s (or two’s) setup. In addition to this
visual feedback, there will be text which says “
USER setup ” or “ FACTORY Setup ” in the curve win-
dow on the far right side of the display. By turning the Data Wheel , you can scroll through setup
library. You will notice the various factory setups as well as all your user setups in the user setup
libraries. You can store up to 100 linked setups, and 100 mono setups. As you do more projects with
your DDP, you will begin to gather all types of setups that you have designed and saved for yourself.
To get out of setup mode and back to program mode, simply touch the program button. The LED associated with
the
Channel button will turn off and the Program button LED will turn on.
While in program mode, you may scroll through the different factory designed programs by simply turning the
Data Wheel . By default, the DDP is shipped with the AutoLoad feature activated. This means that the program
number displayed on the screen is the one which is active, scrolling though the programs cancels any changes
you made to the program you last edited. (See Section 4 for details on editing and storing programs and chains,
and Section 5 for more information on AutoLoad and other utility features) In AutoLoad ON mode, it may be wise
to scroll through programs while in “
Bypass ” mode, or turn down the system’s output levels to avoid possible
gain changes from one program to another. Enter Bypass mode by pressing the Bypass button. Its LED will light
indicating that the DDP is in Bypass mode.
The Bypass Button
The DDP’s meters continue to operate in bypass mode, giving you the ability to change and adjust parameters
while bypassed. Refer to Figure 1 for more information on where the DDP’s metering points are located. It may
take a little practice to adjust parameters without being able to hear the effects of the adjustments. However, this
feature is very useful in that it allows you to change programs, setups or parameters in a live situation without
subjecting your audio system or an audience to the sudden change. Simply bypass the DDP, make your changes,
make sure the meters are showing the desired effect, then take the DDP out of Bypass mode.
Setup Mode
Setup mode is the method by which you will manipulate parameters to make them fit your application exactly.
While every effort was made to produce factory presets that work for most applications, it should be noted that
no two systems, situations or applications are exactly alike. Therefore you will have to change and fine tune the
parameters in the chains that have been provided for you. As you become familiar with this process, you will
become more adventurous and creative in setting up your DDP for various applications. In dual mono mode,
each chain is manipulated separately. In linked mode, the stereo pair shows up on the screen as one chain, and
therefore only needs to be edited once.
