4 Inputs to 1 Output HDMI Switcher & Processor:

Let's start with the basic functions of your Key Digital

®

KD-VPHD4X1 Switcher & Processor.
First and foremost, you purchased the product as a four (4) input to one (1) output switcher,
capable of supporting the 19-pin HDMI Type A connections with HDCP (Copy Protection).

Your Key Digital®KD-VPHD4X1 Switcher & Processor carries whatever
signals are present on your HDMI cables. That means that you can
switch Video as well as Audio. HDMI lets source devices (like your DVD
player, Satellite / Set Top Box, or PC) “talk” with your display or “sink”
device, and your KD-VPHD4X1 Switcher & Processor functions as a true
HDMI repeater to pass along this information. Your switching connection
is truly seamless!

Versatile video and audio Inputs and Outputs:

Next, let's look at the versatility offered by your KD-VPHD4X1 Switcher & Processor. Flexible
Audio I/O interfaces include HDMI, Toslink Optical audio, digital PCM audio, and analog Left &
Right stereo audio. If you have a DVI device you want to switch, or a display with a DVI input,

simply use HDMI<>DVI adapter cable(s).

A built-in Scaler to perfectly match the native resolution of your display:

All of the above features are what you've come to expect from Key Digital

®

. In fact, you can
stop right here, and you would have the perfect solution for all your HDMI switching require­ments. But your KD-VPHD4X1 Switcher & Processor offers so much more…

Wouldn't you like to get the most your HDMI interface has to offer? Sure, HDMI is a pristine,
digital A/V interface. But how do you best interface your 480 sources to the native resolution
of your display? Or what if the HD output from your Satellite / Set Top Box doesn't match
the native resolution of your display? Or what if you want to connect your PC to a projector?
This is where the beauty of your Key Digital

®

KD-VPHD4X1 Switcher & Processor shines

through. With world-renowned Key Digital

®

Clear Matrix ProTMtechnology built right into your
KD-VPHD4X1 Switcher & Processor, any selected input video can be scaled exactly to match
the native resolution of your display. Most of the popular source and display formats and
resolutions are supported.

A built-in Video Processor:

But the power of your KD-VPHD4X1 Switcher & Processor does not end there. An easy-to­operate, full-function, high-quality Video Processor is built into your switcher. For each input,
you can control a broad range of functions, from Brightness and Contrast, to Size, Position,
and e

ven “Zoom” - Aspect Ratio adjustments. Test patterns built-into your KD-VPHD4X1

cher & Processor help you set-up your video system.

So easy to Control:

With so many features and versatility, you may be wondering: Is the KD-VPHD4X1 Switcher &
Processor easy to operate and control? Simply use the convenient front-panel display and
