SOFTWARE
The DDP software works on a hierarchal philosophy. Every program number consists of a processing “setup”
which is built from processing elements that make up a “chain”. There are several preset chains which may be
used to produce a desired effect. Once the desired effect is reached, you may rename and save the setup to a
user library area. The setup’s chain may consist of any or all of the following: gating effects, compression effects,
limiting effects, parametric EQ, sidechain parametric EQ effects, and/or de-essing effects. There are several preset
mono and linked setups. For a complete listing of the setups in the DDP, see section 6. Processing setups are
linked together using True RMS Power Summing™ (see section 8) for superior stereo operation, or two separate
setups may be used in dual mono mode. Each element of the chain has a full complement of parameters that can
be manipulated very precisely via the
Function buttons and the Data Wheel . The following figure shows the
hierarchal building block system used in the DDP.
Setups and Programs
Setups are recalled, manipulated and stored individually. Setups must be recalled into programs before they can
be accessed for use. Each program has a number assigned to it, and consist of a linked setup or two independent
mono setups.. Following is a brief description of the various processor elements that make up the DDP.

Gate
:
The gate is a dbx expander/gate which gives control over the
“ramp” or ratio of the opening, There are also Attack, Hold, and
Release times available. Transient Capture Mode™ is also found in
the Gate section, with variable delay times available.
For a complete list of the parameters available in the gate, see sec-
tion 4. For an explanation of
Transient Capture Mode , and its
implementation in the DDP, see Section 6.
Compressor
:
The compressor offers comprehensive control over all parameters.
OverEasy® is present, with a variable knee feature (VariKnee™)
found only on the DDP. Auto attack and release, and a hold fea-
ture make the compressor more unique than other compressors.
For a complete list of the parameters available in the compressor,
see section 4.
Limiter
:
The limiter offers precise control over Threshold, Attack, and
Release. Release times are set in the measurement standard dB/ms.
For a complete description of the limiter, see section 4.
De-Esser
:
The DDP’s de-esser allows a wide frequency control range
between 800Hz and 8kHz. The range is wide enough to accom-
plish the most demanding of de-essing needs.
For a complete list of the parameters available in the de-esser, see
section 4.
Sidechain EQ / In-Line EQ
:
The DDP offers you the ability to do EQ processing in the
sidechain circuit without having to hook up an extra unit. It’s easy
to perform frequency-specific contouring functions all within the
DDP’s software. Also in the EQ section is the new
TSE™ Tape
Saturation Emulation algorithm, which works in tandem with the
TYPE IV™ Conversion System to capture the essence of any ana-
log signal in a pleasing way never accomplished before.
For an explanation of the EQ functions of the DDP, see section 4.
For information on the
TYPE IV™ Conversion System and its
implementation in the DDP see Section 6.
Dither:
Ditherng capabilities are available to users who have the DDP
Digital I/O module installed. Dithering allows you to optimize the
digital performance of the DDP’s 16 and 20 bit digital output.
For a complete description of dithering, see section 4.
