This KD-CDA3 HDTV Distribution Amplifier accepts virtually any Component Video
input signal (YPbPr) with a matching left and right stereo audio pair (L&R audio can
be substituted by a single digital PCM audio connection), and distributes it to up to
three (3) Display devices around your home or showroom without the loss of signal
quality. “VGA”-like video, called RGBHV, can be used in place of the Component
Video and Audio. A typical hookup will consist of a “Source” device that outputs
Component Video (or Composite Video or S-Video with optional video adapters) such
as a DVD player, Set-Top Box unit, Satellite receiver, digital VCR, Sony-PlaystationÍ,
XBOXÍ, GameCubeÍ or any other consumer video device.
CAUTION: Always test all connections and final operation
first, before sealing cables behind walls or completing difficult wire routings. Since the KD-CDA3 HDTV Distribution
Amplifier does NOT perform video processing, the output
video format and resolution is the same as the input video
format and resolution. This means that the video resolution
is not changed and also that if you input one form of video,
for example Component Video (YPbPr), the output will be in
exactly the same format.

Getting Started
The
KD-CDA3 HDTV Distribution Amplifier
is capable of distributing any Analog
three-wire Component Video (YPbPr) and/or five-wire “VGA”Video (RGBHV) source,
as well as analog/digital audio, to as many as three (3) outputs (typically your displays
or projectors). If your source device output is on a VGA connector, you will need a
breakout cable to RGBHV on separate RCA connectors; RGBHV installations preclude Audio distribution with your KD-CDA3 unit. Once configured, there are no controls to operate and the unit will be “transparent” to your entire installation or application. It’s truly “configure and forget about it” - you are done.

High-quality Component Video (YPbPr) and “VGA” (RGBHV) Equipment
Some of your Source equipment and Displays may have an analog video output that is
called Component Video. Component Video is a three-wire video format, with the video
signals typically labeled YPbPr. Another common analog video output format is RGB (like
the “VGA” outputs on your computer), which typically has separate H&V sync signals.
The KD-CDA3 HDTV Distribution Amplifier has one (1) bank of RCA-type Input connectors,
and three (3) banks of RCA-type Output connectors. Each of the RCA connectors are 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 by using either the left or right audio channel).
Typical Connectors Color-code
*Note: H Sync may also be Yellow on some Source and Sync products
**Note: These are the colors on the KD-CDA3 RCA connectors; however, the corresponding
colors on your Source and Sink products may vary

Connect your COMPONENT VIDEO Source Input
Before supplying power to your KD-CDA3 HDTV Distribution Amplifier unit, connect
the Output of the Component Video Source device you wish to distribute to your displays to the Inputs of KD-CDA3.
The “Source” device Outputs should be connected to the jacks marked “Input” on the
KD-CDA3. After hooking up the “Source” device to the marked input connectors, the
KD-CDA3 will distribute the selected input signal to all of the output connectors.
Alternate Video Inputs
RGBHV
RGBHV installations with separate H & V syncs preclude Audio distribution with your
KD-CDA3 unit. Simply follow the labels on your KD-CDA3 and connect the RGB
Video signals, and H&V Sync signals, accordingly. You may require breakout cables
or adapters to the RCA Inputs of the KD-CDA3.
V
Be careful not to confuse the Red lead of a Component Video (YPbPr) cable with the
Right or Red audio channel. To avoid confusion, note that the Red lead (Pr) from the
Component Video cable is often bundled to the Green lead (Y) and Blue lead (Pb)
from the component cable. Typically an analog Audio cable is comprised of a Rightchannel stereo (Red-colored) connector together with a Left-channel stereo (Whitecolored) connector.
Typically, connecting the KD-CDA3 HDTV Distribution Amplifier into your system is as
simple as matching the proper color-coded connectors. When inserting the RCA connectors use a slight twisting motion when inserting the cables, this assures a proper
connection by seating the RCA connector all the way in. Be sure to use high-quality
75 Ohms cables for the video. When running long lengths of cable please make sure
to use heavy shielded high quality cables.
Caution: For proper operation of the high quality electrical
circuits in your KD-CDA3 unit, do NOT “daisy chain” Inputs:
■
Each Input of the KD-CDA3 has its own 75 Ohms termination
■
Do NOT feed a Source to multiple KD-CDA3 Inputs without
proper Distribution equipment
Note:
Since the KD-CDA3 HDTV Distribution Amplifier does NOT perform video
processing, the output video format is the same as the input video format. This
means that the video resolution is not changed and also that if you input one form of
video, for example Component Video, the output will be in exactly the same format.

Connect your Output Displays
Now that the Video and Audio Inputs are connected to your KD-CDA3, run each of
the individual set of Output connectors to their respective “Display” devices. The
three (3) Output port banks are labeled Output 1, Output 2, and Output 3.
Always test all connections and final operation first, before sealing cables
behind walls or completing difficult wire routings.
Caution: For proper operation of the high-quality electrical
circuits in your KD-CDA3 unit, you MUST ensure for each Output:
■
Each run of YPbPr cable MUST be the same length
■
Maximum run length = 300 feet
Output 2
Output 1Output 3
Input
S-Video
For SDTV S-Video, simply follow the labels on your KD-CDA3 and connect the Y and
color (chrominance) signals. Use the “Y” Input of the KD-CDA3 for the S-Video Y signal. Note that if you may use either the Pr or Pb Input for the S-Video chrominance
signal. However, be sure to correspondingly use the same (Pr or Pb) when driving
your displays. For example, if you input the S-Video color signal on the Pr path, then
you MUST use the Pr Outputs of the KD-CDA3 to drive your S-Video displays. You
may require breakout cables or adapters to the RCA Inputs of the KD-CDA3.
Composite Video
SDTV Composite Video, frequently called CV or CVBS, is a single-wire video format.
You must use one of the three KD-CDA3 inputs for the Composite Video Input, and
correspondingly use the same Output label to drive your Composite Video display.
For example, use the “Y” Inputs and Outputs. This way, you will have three (3)
Composite Video Outputs. You can achieve a higher level of CVBS distribution, for
driving up to seven (7) Composite Video displays, by feeding back the KD-CDA3
Outputs to the open KD-CDA3 Inputs. Refer to the Application Example for
Composite Video provided later in this Operating Manual. You may require breakout
cables or adapters to the RCA Inputs of the KD-CDA3.

For added safety and protection it is always recommended to use a good quality
surge protector.
Use a reliable “Source” to test your connections (like a DVD player) before routing or
hiding any wires behind walls or ceilings.
Mounting and Maintenance instructions
The KD-CDA3 HDTV Distribution Amplifier is built for years of trouble free operation.
It can be installed in any home theater, showroom, or other system using multiple displays. Cleaning or maintenance is usually not necessary, but if needed use a soft
non-abrasive dry cloth to wipe the dust from the unit.
Since the KD-CDA3 is an electrically powered device, it will produce a small amount
of heat; therefore it is recommended to leave a few inches of room around the unit to
dissipate this heat. You may attach the mounting clip provided to a suitable location, and
then carefully clip the KD-CDA3 into the mounting clip once the mounting clip is secure.
Make sure to use the correct wires when making the connections to the “Display”
device (use the color matching system if possible).
The same consideration applies to the audio interfaces. Both analog and digital output options are provided on the KD-CDA3 HDTV Distribution Amplifier. Your analog
Audio may drive the speakers in your display. Your digital Audio may connect instead
to an A/V receiver having coaxial digital (PCM) interfaces for decoding surround
sound signals.
Next, plug the external Power Supply provided with your unit into an appropriate* wall outlet.

If you need to expand the distribution capability of your KD-CDA3 HDTV Distribution
Amplifier, simply use one of the Outputs of the unit that may now be going to one of
your displays, and connect that output to the input of another Key Digital
®
Analog
Distribution Amplifier. The total distribution capability is the sum of the total Outputs
of all units, minus one. For example, using the KD-CDA3 3-output Distribution
Amplifier, cascaded with the Key Digital
®
KD-CDA6 6-output Distribution Amplifier,
you will need to use one of the three Outputs of the KD-CDA3 to drive the Input of
the Input of the KD-CDA6. Hence, you will be able to drive your Source to up to 8
displays (3 - 1 + 6 = 8).
Remember, you MUST only use the Power Supplies intended for each product, as
provided with each Unit. Do not attempt to share or swap Power Supplies.

PROBLEM: No power to the unit.
You
MUST
use the Power Supply provided with your unit:
Verify that the external Power Supply provided with your unit is properly connected
to a standard 110V household outlet.
Check to make sure that the power connector is properly inserted into the jack on
the KD-CDA3.
Check and verify that the wall outlet is active by plugging in a component known
to be operational, such as a desk lamp.
Unplug the adapter from the wall and verify that the cable is not cut or interrupted
anywhere.
If none of the above works, please contact Key Digital
®
technical support. See
“How to Contact Key Digital
®
at the end of these Operating Instructions.
PROBLEM: You are not able to view a picture on any or all of your Display
devices.
Check to make sure that the connected Display devices are capable of operating
with the format and resolution of the “Source”. For example, if the Source (such as
your DVD player) outputs Component Video (YPbPr) at 1080p, but your display
device only accepts 720p RGBHV, then there is a compatibility problem among
your equipment.
If any Display device connected to the output of the KD-CDA3 is not capable of
handling HDTV-compatible video signals, make sure that the “Source” device connected to the Input of the KD-CDA3 for distribution is set to output SD-compatible
signals (Standard Definition or 480i).
TROUBLESHOOTING
If you encounter problems or find that the KD-CDA3 unit fails to properly distribute
the “Source” signal (such as from your DVD player) to the Video Display(s) and/or
Audio system(s), it is suggested you first check for the following:
■
Verify that your Source device and displays are functioning properly without the
KD-CDA3. Connect your Source directly to your displays and check for proper
operation. If you are not able to obtain satisfactory operation, correct the problem
before proceeding with the KD-CDA3 in the path.
■
Validate that all of the connections are made at all points: the Source Output, the
KD-CDA3 Input and Outputs, and your Display and Audio system Inputs.
■
Be sure that you have supplied power to the KD-CDA3 unit, using ONLY the Power
Supply adapter provided in the package with your unit.
■
Ensure you have good-quality cables, of equal length, no greater than 300 feet
each in length.
Troubleshooting Guide
If you still encounter a problem with your unit or installation after checking for the
items above, you may find it helpful to review the Troubleshooting Guide, next page:
KDCDA3_OperInstructions.qxd 1/4/06 12:58 PM Page 20
KD-CDA3 Operating Instructions
Page 23 of 29
KD-CDA3 Operating Instructions
Page 22 of 29
PROBLEM: You are able to view a picture but there is inter ference, noise, or
hum bars visible on the image on one or more of your Display devices.
This can happen when crossing power lines when routing the cable from the
“Source” device to the KD-CDA3, or when routing the cables from the KD-CDA3 to
your Display device(s).
If crossing power lines is inevitable, make sure to use heavy, shielded, high-quality
Video and Audio cables.
Sometimes using a shielded and noise filtering surge protector can eliminate noise
in power lines.
PROBLEM: There is no Audio from your Audio system.
Check to make sure that the volume is turned up to an audible level on the “Source”
device as well as the Display device. If you still encounter a problem, then:
Make sure that the Audio connections were properly configured, and that your display has speakers. Check the connections from start to finish for the Left (white)
and Right (red) stereo Audio channels.
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 an AV-Receiver or amplifier capable of decoding Dolby Digital
®
.
For “VGA” (RGBHV) operation, verify that the Sync is either present on the Green
connector or the H & V connectors. Make sure you have properly connected Sync
from the Output jacks of your “Source” to the Input of your KD-CDA3, and that the
corresponding Outputs of the KD-CDA3 are properly connected to your Display(s).
Note: For Component Video (YPbPr), sync is present on the “Y” Channel.
PROBLEM
:
You are able to view a picture on the Display(s), but the image
is Black and White, Green, or Pink in Nature.
This is indicative of a mismatch between “Source” and Display devices in the
Video connections. Make sure that your Source and Displays are all of the same
format. For example, if the Source outputs “Component Video” (YPbPr) then the
connections to your Display(s) must also be via the “Component Video” path (and
not the VGA).
Make sure that the Component Video (YPbPr) or “VGA” Video (RGBHV) connections are properly maintained throughout the entire chain from the Source, to the
KD-CDA3, to your Display device(s).
PROBLEM: There is a picture but it is “scrolling” across the screen of one
or more of your Display devices.
This happens when the Input signal from your Source device is not compatible
you’re your Display, or if there is a problem with the Sync signal(s).
For example, if one or more of your Displays connected to the Output of the KDCDA3 is not capable of handling HDTV-compatible video signals, make sure that the
“Source” device is set to output SD- compatible signals (Standard Definition or 480i).
For “VGA” (RGBHV) operation, verify the presence of the Sync signal.
