Note before attempting to Hookup:
The KDS-CDA12 and KD-DA6 have similar perform-
ance and installation instructions. In essence the
KD-CDA12 is double KD-DA6 housed in one robust
unit. The following instructions will apply to both
units except when specifically noted.
Product Hookup:
*When unpacking the unit make sure to make all
hookups before plugging in the power adapter.*
This unit will receive any component video input sig-
nal (Y, Pr, Pb) with matching left and right stereo
audio channels (L/R audio can also be substituted
by a single digital PCM audio connection) and dis-
tribute it to several “Display” devices around your
HomeTheater or showroom without the loss of sig-
nal. A typical hookup will consist of a “source” device
that outputs component video (for example: DVD
player, Set-Top Box unit, Satellite receiver, digital VCR,
TM
TM
TM
Sony-Playstation , XBOX , or GameCube *with
optional component video adapter*, and several
other consumer devices.)
The “Source” device should be connected to the
ports marked “input” on the
KD-DA6 or the KD-CDA12. After hooking up the
“Source” device to the marked input connectors , the
KD-CDA12 or KD-DA6 will distribute the selected

input signal to all of the output connectors (the com-
ponent video and audio output connectors are
marked “output” the KD-DA6 has one bank of 6
(Marked 1 through 6) sets of output connectors. The
KD-CDA12 has two banks (Marked Channel 1 and 2,
each corresponding to their respective inputs) of 6
TM
each output connectors. Each of the RCA -style
connectors are conveniently color coded to match
most “Source” and “Display” devices available in the
consumer industry; Red, Green and Blue for
Component video; White, and Red for left and right
audio respectively (PCM audio can be distributed
using either the left or right audio channel). When
applicable, connecting the KD-DA6 and the KD-CDA12
is as simple as matching the proper color coded con-
nectors.
TM
*When inserting the RCA style connectors use a
slight twisting motion when inserting the cables, this
TM
assures a proper connection by seating the RCS
connector all the way in. *
*Be careful not to confuse the Red lead of a compo-
nent video cable with the Right or Red audio channel.
Most often the audio wire is of thinner gauge wire
and is together with the White or Left audio lead! The
Red lead from the component video cable is often
attached to the Green and Blue lead from the compo-
nent cable as well. *
* When running long lengths of cable please make

sure to use heavy shielded good quality cable like
Key Digital TechFlex heavy gauge AV cable (refer to
main catalog for cable selections, or KeyDigktal
interactive website: ww.key digital.com.
Now that all the input(s) are done it is time to con-
nect the outputs to the respective “Display” devices.
Run each of the individual set of output connectors
to their respective “Dusplay” devices. Make sure to
use the same caution when making the connections
to the “Display” device (use the color matching sys-
tem if possible.)

The KD-CDA12 can be configured in 3 separate
modes:
Mode1: 2 inputs each driving 6 outputs each ‡ 2X6
Mode (factory Default).
Mode2: 1 input driving 12 outputs with the unused
input driving the next amplifier ‡ NX12 mode.
Mode 3: 1 Input driving 12 outputs ‡ 1X12 mode.
Mode 1: The KD-CDA12 has two sets of inputs! This
essentioally allows for independent connection of
two “Source” devices and usage of the KD-CDA12 as
two separate KD-DA6’s. Using this configuration it is
possible to distribute two discreet Audio/Video sig-
nals to two banks of 6 different “Display” devices
each (use the hookup described above for the KD-
DA6). The dipswitches on the unit should be set to
the following:

Mode 2: The KD-CDA12 can also be cascaded or
“Daisy Chained”. Using hookup-method allows multi-
ple units to be connected in series. One of the two

inputs is for receiving the Source or input signal; the
other input is used for the “Loop-Through” signal, for
passing the signal to the next amplifier in the chain
of series. Either input can be used as the “Source”
input or as the “Loop-Through” input (to send the sig-
nal to the next KD-CDA12 or KD-DA6.) The Mode 2
setting is used for all KD_CDA12 in the chain except
for the last unit which must be set to Mode 3 (See
below for appropriate dip switch setting). A maxi-
mum of 4 KD-CDA12’s can be connected in a “Daisy
Chain” using this hook-up method.

Now that all the installation is done it is recommend-
ed to double check all connections before connect-
ing the external power supply. Once every connec-
tion has been verifiwed, plug the external power sup-
ply connector into the power input jack of the KD-
DA6 or KD-CDA12. Once power has been applied, a
green light should show the power “ON” status on
the front of the unit. Use a reliable “Source” to test
your connections (Like a DVD player).
Mounting and Maintenance instructions:
TheKD-DA6 and KD-CDA12 are built for years of trou-
ble free operation. This unit can be installed in any
Home theater, showroom or other configuration.
Often the KD-DA6 or KD-CDA12 is moved to the back
or behind the other AV “Source” devices. Cleaning or
the maintenance is not necessary, if needed use a
soft non-abrasive dry cloth to wipe the dust from the
unit.

* Since the KD-DA6 and the KD-CDA12 are powered
devices they will produce a minimal amount of
heat, therefore it is recommended to leave enough
room around the unit to dissipate this heat. *
Troubleshooting:
If, after properly connecting all of the devices in the
system, the unit fails to properly distribute the
“Source” signal, try any of the suggestions below.
No power to the unit.
Make sure that the external power supply is properly
connected to a standard 110V household outlet.
Check to make sure the power indicator light is
green. If there is no power light, check and verify
that the wall outlet is active by plugging in a known
good component (like a desk lamp). * For added
safety and protection it is always recommended to
use a good quality surge protector. *
Check to make sure that the power connector is
properly inserted into the KD-DA6 or KD-CDA12.
Unplug the adapter from the wall and verify the cable
to make sure that the cable is not cut or interrupted
anywhere.
If none of the above works, please contact Key
Digital technical support hotline at (888) 258-2028
or send an e-mail to [email protected].

There is no signal displayed on the “Display”
device.
Verify the Sync or Green connector on all of your
video connections; make sure it is connected to the
correct input/output jack of the “Source” as well as
the “Display” device.
Make sure that the “Source” signal is of a valid for-
mat that can be displayed by the connected
“Display” device; for example: if the “Display” device
connected is not capable of handling HDTV compati-
ble video signals make sure that the “Source” device
is set to output SD (Standard definition or 480i)
compatible signals.
There is a signal but it is Black and White, Green or
Pink in Nature.
This is indicative of a mismatch between “Source”
and “Display” device in the component video connec-
tions.
Make sure that the “Source” signal is of a valid for-
mat that can be displayed by the connected
“Display” device; for example: If the “Display” device
connected cannot handle HDTV compatible video sig-
nals make sure that the “Source” device is set out-
put SD (Standard definition or 480i) compatible sig-
nals.
I have a picture but it is scrolling across the
screen of my “Display”.

compatible with the “Display” device. Make sure
that the “Source” signal is of a valid format that can
be displayed by the connected “Display” device; for
example: if the “Display” device connected is not
capable of handling HDTV compatible video signals
make sure that the “Source” device is set to output
SD (Standard definition or 480i) compatible signals.
I have a picture but there is noise or “hum bars”
visible in the image.
This could happen when crossing power lines when
routing the cable from the “Source” device to the KD-
DA6 or KD-CDA12, or when routing the cables from
the KD-DA6 or KD-CDA12 to the “Display” device. If
crossing power lines is inevitable, make sure to use
heavy shielded good quality cable like Key Digital
techFlex heavy gauge AV cable (refer to main catalog
for cable selections, or Key Digital’s interactive web-
site: www.keydigital.com
Sometimes using a shielded and noise filtering surge
oritector can eliminate noise in power lines.
I have No Audio.
When connecting the Left and Right (White and Red
connector) stereo audio channel make sure that the
connectors are properly connected to the “Source”
device as well as the “Display” device.
Make sure that the volume is turned up to an audible
level on the “Source” device as well as the “Display”
device.

When using the Digital Audio connection “PCM” or
coaxial audio, make sure that the “Display” device is
capable of decoding this compressed bit stream of
audio information. Most often when using the “PCM”
audio function, the audio will be connected to a
Dolby Digital® capable AV-Receiver or amplifier.
