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 diffi-

cult 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 pre-

clude Audio distribution with your KD-CDA3 unit. Once configured, there are no con-

trols to operate and the unit will be “transparent” to your entire installation or applica-

tion. It’s truly “configure and forget about it” - you are done.

CAUTION: When unpacking the unit, make all hookups and

connections before plugging in the Power Adapter provided

with your unit. Do NOT apply power to the unit until all Video

and Audio connections have been made to your KD-CDA3

unit from the “Source” device to the Display(s) and/or Audio

system(s). You MUST use the Power Supply provided with

your unit or you VOID the Key Digital®Warranty and risk

damage to your unit and associated equipment.

You may wish to distribute the signal from your DVD Player, Video Game, Cable TV,

Satellite and Terrestrial DTV set-top receiver, Digital Video Recorder, D-VHS, S-VHS, or

VHS VCR “Source” to several Displays. Typical Application Examples of how you may

use the KD-CDA3 HDTV Distribution Amplifier in your installation are shown here.

Because not all consumer equipment marketed uses RCA connector interfaces, it

may be necessary to employ BNC-to-RCA, VGA-to-RCA, and other adapter plugs

and/or cable assemblies to interface these various devices to your KD-CDA3 HDTV

Distribution Amplifier.

CONNECTING A/V EQUIPMENT TO YOUR UNIT

In this section, you will be instructed as to how to connect all of your A/V Input and

Output devices to your KD-CDA3 HDTV Distribution Amplifier unit.

Setting up your KD-CDA3 HDTV Distribution Amplifier for operation:

Your KD-CDA3 HDTV Distribution Amplifier is easy to configure and operate. Simply

connect your Input analog Video and analog or digital Audio source, and drive up to

three (3) displays. For Component Video applications, you can also simultaneously

drive your displays or Surround Sound processors with digital or analog Audio.

There are no other controls, and no other setup is required other than supplying

power to your unit with the Power Supply adapter provided with your unit.

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 respec-

tively (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

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 dis-

plays 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.

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 Right-

channel stereo (Red-colored) connector together with a Left-channel stereo (White-

colored) 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 con-

nectors 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 sig-

nal. 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.
