KDS, the HD HD View 6 provides economical signal distribution

from any HDTV or SDTV Component Video source (YPrPb) to compo-

nent HDTV-ready monitors. It uniquely resolves current connectiv-

ity problems experienced by HDTV manufacturers and retailers, by

effectively "gluing" together HDTV equipment manufactured to

diverging technologies. HD HD View 6 thereby enables a best-in-

class assembly of HDTV/SDTV sources and displays, yielding color-

rich, artifactfree, and pristine HDTV and SDTV signals

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,

Sony-PlaystationTM, XBOXTM, or GameCubeTM *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

OPERATING INSTRUCTIONS

Model KD-DA6

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

each output connectors. Each of the RCATM-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.

*When inserting the RCATM style connectors use a

slight twisting motion when inserting the cables, this

assures a proper connection by seating the RCSTM

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

OPERATING INSTRUCTIONS

Model KD-CDA12

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.)

Additional installation notes specific to the KD-

CDA12:

OPERATING INSTRUCTIONS

Model KD-DA6

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:

_1 2 3 4 _5 _6 7 8

SW1 ON OFF ON ON OFF OFF ON ON

_________________________________________________________________________________________

SW2 ON OFF ON ON ON OFF OFF ON

* Please refer to the illustration for 2X6 termination

mode. *

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

OPERATING INSTRUCTIONS

Model KD-CDA12

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.

The dipswitches on the unit should be set to the fol-

lowing:

_1 2 3 4 _5 _6 7 8

SW1 OFF ON OFF OFF ON ON OFF OFF

_________________________________________________________________________________________________

SW2 OFF ON OFF OFF OFF ON OFF OFF

* Please refer to the illustration for NX12 Daisy

Chain.*

Mode3: The KD-CDA12 can can be configured to dis-

tribute 1 input “Source” to 12 different “Display”

devices.

The dipswitches on the unit should be set to the fol-

lowing:

* Note: The factory default setting of the dip-

switched is 2x6 mode! *

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.

OPERATING INSTRUCTIONS

Model KD-CDA12

* 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 tech@keydigital.com.
