Use only floated test equipment. Oscilloscopes, PCs, signal generators, voltmeters, etc. must be connected
through a three-to-two-prong adapter to avoid ground loops and other conditions that may damage the
amplifier.
Use only the supplied power cord.
Do not place the power cord near heat sources such as heaters, or place it in a position where anyone could
walk on, trip over, or roll anything over it.
Do not attempt to disassemble or modify the internal components in any way.
Opening the unit requires a written authorization from KSC Industries.
Do not insert objects (such as screwdrivers) through the amplifier’s perforated caging. This could be hazardous
to you and could cause permanent damage to the Plate Amplifier. Doing so, voids the product warranty.
Do not touch any speaker leads together from different drivers while the unit is powered; this could damage
one or more amplifier modules.
Do not touch the aluminum enclosure with any of the speaker leads while the unit is turned on; this could
damage the associated amplifier module.
Do not place the Plate Amplifier close to a hot surface.
Read the Amplifier specifications (page 22) before connecting loudspeaker loads and applying input signals.
Check the Connection Diagrams section (page 12) to properly connect the drivers and avoid damage to them.
Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical
shock, short-circuiting, damages, fire or other hazards. These precautions include the following:
Power supply/Power cord/Grounding
Do not open
Fire/burn/damage warning
Loudspeaker connection

  
Your DDC 500 Series Amplifier is factory programmed to 0dB Output Gain; please take your precautions
before applying any audio signal to the input.
Read the Amplifier specifications (page 22) before connecting loudspeaker loads.
Do not operate the LF, MF and/or HF amplifier sections (depending on the model) to Max Power when all the
channels are set to flat response without crossover filters. Such settings will force the amplifiers with lower
power rating to exceed the maximum output and may result in failure.
Do not run unfiltered high frequency test signals (5-20 kHz) for more than a few seconds since this could cause
permanent damage to the Amplifier.
Make sure to run the amplifier with all channels connected to a load.
Always turn off the unit when not in use.
Operation
KSC Industries cannot be held responsible for damage caused by improper use or modifications to the amplifier system.

Signal Throughput Connector
This connector allows a pass through of the
audio signal to other devices. One
application might be a daisy-chain setup
connecting more than one DDC Series
Amplifier.
Signal Input Connector
Use this connector to input the source audio
signal to be processed and amplified by
your DDC unit.
LED Power Indicator
This LED will be lit as long as the system is
ON (connected to AC line voltage.)
LED Protection Indicator
This LED will turn on temporarily when AC
is applied to the unit (as part of the start-up
sequence) and permanently when thermal
protection has been triggered or when a
short circuit has been detected.
Serial Communication Port (USB)
This port allows communication between
the DDC Series Amplifier and your
computer. This communication is necessary
to load configuration files and to allow data
transfer during the process of fine tuning
and customizing your system.
Connectors & Indicators
Description
AC Power In Receptacle
Connect the provided AC cord to the line
voltage (120V or 230V depending on the
product model) here.
AC Power Out Receptacle
This is a helpful AC power pass-thru
connection which can be used to connect
several DDC units in a daisy-chain fashion
avoiding the need for additional electrical
outlets.
Heatsink
An important part of the DDC Series design
is the heatsink plate, which minimizes the
chances for overheating, letting the
amplifier modules and the overall system
run cool.
Aluminum enclosure
All DDC Series Amplifiers come shielded
with a perforated aluminum enclosure to
provide protection.
Speaker Connector
Use this connector to plug in the speaker
cable (provided in the package) and to
connect the wires to the corresponding
driver, depending on the amplifier model.

Connect the DDC 500 Series Amplifier according to the drawing shown below.
System Connection
Once you connect the unit to the computer and supply AC Power,
the computer will find the new hardware.

  
Once the unit is connected as indicated on the previous page, you can test the operation and performance of
your DDC 500 Series Amplifier in its factory configuration scheme.
Acoustic Tests
oIf you want to perform acoustic tests make sure your system is wired to the
drivers according to the diagram for your specific model (check Connection
Diagram section on page 16).
Electrical Tests
oIf you need to run electrical tests substitute the loudspeakers for resistor
loads according to specs (check Appendices section for specifications on
your particular amplifier model).
To establish communication between your DDC 500 Series Amplifier and a computer,
Follow these instructions carefully:
Basic Operation
PERFORMANCE TESTS
Launch the D-Pro software program you installed previously (refer to
Software Installation section on page 11 if you haven’t done so).
INTERFACING WITH THE COMPUTER
1
2
Click on the Communications TAB and click on the Select COM Port option.
This step is required once. You don’t need to repeat it every time you
use the software, unless you’re connecting the Amp to a different
computer.


Click on EXIT to close this window
A new window will show up. Click on the button labeled SCAN.
3
The program will scan for an available COM Port and once it finds it,
it will use it to communicate your DDC Amplifier with the PC.
As soon as the program finds and assigns a Communications Port
you will see the word SUCCESSFUL appearing in the scan status
box.
Interfacing with the computer
Your amplifier is now ready to receive information from the computer
and process audio through powerful DSP chips and functions.

  
The only goal of this section is to show you how to access the DSP functions and modify parameters in
real time so you can hear and/or see the difference instantaneously. To fully understand and learn all about
the software functions please refer to the D-Pro Windows Software User’s Manual.
1
Click on the Configuration TAB and click on DSP I/O Board Configuration option.
2
A new window will show up.
Click on the drop-down arrow and click on your amplifier model.
A BRIEF LOOK AT THE SOFTWARE PROGRAM
With this step we will tell the program to load the default
configuration for the Amplifier model we’re testing.



Click on EXIT to close this window
A warning will show up:
“This action will write over your current DSP configuration.
Do you wish to continue?”
You can click on YES due to the fact that you’re running the software for the 1st time
and you don’t have any user configuration files to lose.
If you had been working for hours on a custom configuration and you attempted to
load the default I/O Board Configuration, you would lose all your data if you didn’t
save it before.
A brief look at the software program

  
Click on the Configuration TAB and click on DSP Block Configuration option.
This will take you to a new screen that shows a Block Diagram
representing all the DSP functions available to you. Clicking on any
of these blocks will bring up a new window containing all the
parameters and controls necessary to make any desired adjustments
to the corresponding block.

how to transfer your modifications (temporarily or permanently) to the Amplifier, please
refer to the D-Pro Windows Software User’s Manual.
5
Click on any of the blocks to access its respective set of controls and graphical
representations.
You can modify them as you wish, but in order to apply your changes in real time (for quick
checking) you will need to enable the LiveUpdate.
To do this, go to the Communications TAB and click on Enable LiveUpdate.
A brief look at the software program
6
Change the DSP functions freely.
Filters, soft volume, limiter/compressor, etc…
All modifications you make will affect the output in real time. If there are drivers connected
to the unit you’ll hear how the sound changes immediately.
Once you’re done testing the program simply close it without saving anything
A message will pop up on the screen telling you that the Live Update
option is being activated. Once it disappears you can continue.
You can access the manual directly on the D-Pro screen.
Just click on the HELP! TAB and select the Launch User’s Manual
option.
