Digital Signal Processing

Designing crossovers, equalizers and level control can be a complex process for

manufacturers of powered loudspeakers. Even high-precision analog components will

produce less than optimal performance. And whenever you change drivers or cabinet

dimensions, all-digital signal processing offers unprecedented ﬂ exibility for original

equipment manufacturers. D-Pro

™

Digital Audio Processing is built into every KSC

Industries Digmoda Series Professional Power Ampliﬁ er. Our DSP provides easy-to-

implement crossover ﬁ lters, system equalization, speaker protection, noise gates,

limiting, delay and more. These and other unique features make Digmoda Plate Ampliﬁ ers a

unique building-block choice for OEMs.

D-PRO DIGITAL AUDIO PROCESSING

consists of two components: a Windows

XP-

compatible

D-Pro Software Application

which, via an easy-to-use Graphical User Interface,

lets OEM users adjust each system parameter; and a

DP Series Digital Audio Processor

(DAP) Module

included within each plate amplifier that utilizes up to 16 Bi-quad filters

per channel to provide the necessary ultra-precision, 24-bit/96 kHz DSP functions to

implement the system settings developed by the D-Pro Software. During manufacturing,

you simply connect a PC or laptop to the plate ampliﬁ er via a USB port, and load the relevant

crossover, EQ, overload protection and delay settings into the ampliﬁ er’s non-volatile ﬂ ash

memory.

It couldn’t be easier.

1. Reduced Time to Market ...

New and updated products can be designed and put into production in a fraction of the

time required with conventional ampliﬁ er designs and analog components.

2. No Tolerance Stack ...

All-digital D-Pro circuits are totally predictable and produce results accurate to a fraction

of a dB at any crossover frequency, bandwidth and level adjustment. Ultra-accurate

results are just a keystroke away.

3. More Granular System Performance …

Because they are generated with all-digital precision, D-Pro crossovers, dynamics and

EQ circuits are surgically accurate, which translates to tight, predictable response across

the entire frequency range.

4. One SKU Fits All ...

Any Digmoda Plate Ampliﬁ er can be used within a number of different loudspeaker

models, with conﬁ guration-speciﬁ c D-Pro crossover, EQ and protection settings to suit

different drivers and cabinet designs.

The

DP Series DAP Modules

provide all of the DSP necessary to store and implement

settings developed by the D-Pro Software. Depending upon the I/O conﬁ guration of the

host plate ampliﬁ er, two versions of the DSP cards are available: the DP130 Module is a

one-in/three-out processing module; while the

DP240 Module

provides a two-in/four-out

conﬁ guration. An array of Bi-quad IIR ﬁ lters per channel can be user-conﬁ gured in

choice

Low-pass

High-pass

Band-pass

All-pass

conﬁ gurations. (IIR refers to the ﬁ lter’s Inﬁ nite Impulse Response function, which is non-zero

over an inﬁ nite length of time. IIR ﬁ lters can achieve a given ﬁ ltering characteristic using less

memory and calculations than a similar Finite Input Response/FIR ﬁ lter.)

Consider the many practical

and ﬁ nancial advantages of

the Digmoda Plate Ampliﬁ ers:

➤ Speed up system development

and evaluation.

➤ Eliminate component tolerance

errors via all-digital circuitry.

➤ Add enhanced systems

performance.

➤ Dramatically reduce inventory.

➤ Available in single-ampliﬁ er and

multi-way conﬁ gurations.

➤ Offer power outputs from 200W to

1,000W per channel.

➤ Offer variable plate sizes for

different applications.
