Glossary
A signal conditioning process that reduces a source signal's dynamic range. Loud signals
get softer and softer signals get louder. The threshold in this effect is the amplitude level
below which a signal is passed without change.
A Config (short for CONFIGuration) controls how the DP / 4 handles signals by
determining the number of input sources to be processed, how they are to be
interconnected, and where the outputs will appear.
There are several uses of the term Config and it is important to understand the
distinctions between them. Some terms used in these definitions may not yet be familiar,
but they are described later in this section. Read these definitions again after reading the
rest of the section.
Config(uration) - This general term refers to the current signal routing arrangement that
the system is using. It includes all routing parameters.
Config Parameter - Anyone of the parameters which appear in Edit mode when the
Config LED is on.
Input Config - The Config parameter which controls how many input signals are to be
processed by the DP /4 (equivalent to Source Config).
Config Preset - The DP / 4 preset type which contains algorithms and parameter settings
for all of the units as well as all of the Config parameter settings.

Important: Setting up the correct Config is the most important action when
using the DP / 4. The Config controls how the system operates in many important
ways. It is very important to understand this concept clearly in order to avoid later
confusion.
Please read the rest of this section and then refer to Section 3 - Config
Parameters for more details on this essential concept.
A parameter in the DP / 4 that allows control of frequency information found in reverb
algorithms. You can use damping to customize the perceived size and ambience of an
environment (making it wetter/ drier or brighter/ darker).
A specialized algorithm that reduces the level of sibilance in a source signal through
selective high frequency compression. This sibilance is usually heard as an "s" sound in
speech, hence the name De-esser.
Digital Delay Line (DDL) An algorithm that causes source signals to be moved in time relative to the
original signal. These" delayed" signals are used to create a myriad of audio effects, such
as echo and reverb.
Dual Mono
A term used in the DP / 4 to describe one signal routing option. Two inputs are treated as
separate mono signals rather than as a stereo pair. This option processes the two input
sources as two discrete mono outputs. A useful option when more individual effects are
needed.
Early Reflections Early reflections create the sonic information that determines how we localize and
perceive size in ambient spaces. In the case of a room, where the signal is bounced off all
surfaces (walls/ceiling/floor), the perception of the summation of these delayed signals
creates what we term ambience. In the DP /4, you can control these delays to create
various environments.
Echo
XVI
A delay that is perceived as a discrete repeat of the original sound. A classic example of
an echo is the effect of shouting into a canyon. You will hear your voice delayed and
repeated throughout the canyon. Generally, echoes are created by long delay times.
