Introduction

Key Digital®HD Flash 4TM(Model KD-SW4x1) is a versatile multi-input audio/video switcher
for connecting video and audio sources to a TV video display or monitor. It is the ideal solu­tion when your TV, monitor, or receiver does not have enough video and audio inputs. It fea­tures 4 independent component video/audio inputs with one component video/audio output.
Digital audio (PCM)or analog audio (L & R) can also be switched through the Flash 4

TM

. All

input selections are clearly displayed on the front panel with blue LED indicators.

Using the Flash 4TM, you can switch the virtaully any A/V input device

• DVD players

• Electronic game boxes

• Cable TV, satellite, and terrestrial DTV set-top receivers

• Digital video recorders (DVRs)

• D-VHS, S-VHS, and VHS VCRs

You can also switch S-Video (with adapter) and composite (single-wire) video signals from
VCRs, digital video recorders, and satellite set-top receivers through the Flash 4

TM

.

Color-coded RCA jacks are provided on the rear panel for fast and easy hook-up.

Switching can be done in any of three ways:

• Manually, using the front panel button.

• Remotely, using the supplied infrared remote control

• Remotely, using a touch panel and RS-232 commands

Connecting Your A/V Equipment

Connecting your A/V equipment to the Flash 4TMis a simple process. Start with Input #1 and
proceed to the next higher input each time you add an A/V device.

First, determine the video signal format you want to connect. If an A/V device has compo­nent YPrPb (three-wire) video outputs, use them for best video quality. If component video
outputs are not available, use the S-Video output instead. Composite video signals can also
be switched through the Flash 4

TM

, but these signals will have the lowest overall video quality.

This is comparative statement for Component, S-Video or Composite formats. The Flash 4

TM

does not degrade any HDTV or SDTV video signal.

Next, deter

mine whether you want to use the device’

s analog audio outputs or the digital

audio output. Use analog outputs if you ar

e switching audio to the analog inputs of a TV or
monitor. Use the digital output if you are switching audio to an A/V receiver with a digital
audio input.
