ANALOG CONNECTIONS
The DDP is designed to interface as easily as possible to your system. To that end, it may be used in the insert
path of a console, in a patch bay, or as a group output processor. Figure 4 shows the DDP used in an insert point
of a console. Analog audio connections are made using standard XLR or 1/4” TRS cables. The rear panel is
marked as “Channel One” and “Channel Two” to correspond to the way the DDP’s software identifies the two
channels of audio. If you are used to using the “left/right” identifiers and plan to use the DDP in such a system,
just ensure that each channel of the DDP is consistent in its hookups between the inputs and the outputs (ie: if
you use the DDP’s Channel One input in the “left” side of your system, make sure that Channel One’s output also
goes to the “left” side of your system). Refer to the illustration of the DDP rear panel on the previous page.
The DDP uses wide ranging analog input and output gain pots that allow the use of either -10dBV or +4dBu con-
nections without the use of a sensitivity selection switch.
DIGITAL CONNECTIONS
If you have purchased the optional digital input / output module for your DDP, you have the ability to perform
complex dynamics processing tasks on digital signals without having to leave the digital domain. The DDP Digital
I/O also offers the ability to convert analog to digital signals using the proprietary dbx TYPE IV™ Conversion
System. The dbx TYPE IV™ algorithms capture an analog signal into the digital domain while maintaining the best
qualities of an analog recording, and minimizing the sometimes harsh qualities of digital recordings.
When the digital card is installed in the DDP, the analog outputs are still operative, giving you simultaneous ana-
log and digital output. When digital input is selected via the
Utilities
button, the analog inputs are disabled. For a
complete description of the Utilities functions see Section 5.
