4x1 HDMI Switcher

Route Any One of Four HDTV Sources to One HDTV Screen

4 HDTV Sources + 1 HDTV Screen = High Definition Versatility and Performance

The 4x1 HDTV Switcher offers unparalleled flexibility in the setup of high definition theater and electronics systems. A plug and play solution, the 4x1 HDTV Switcher connects four HDTV source devices, including satellite set-tops, DVD players, TiVo systems and even DVI-based computer systems, and links them to one high definition screen. You simply select what source will be viewed on the screen using the Switcher or its IR remote control. It can also be controlled using any universal programmable remote device, offering an alternative to multiple remote control confusion. An effective and reliable solution that eliminates the need to purchase several high-definition screens, the 4x1 HDTV Switcher requires no additional power supply to operate. Yet it is equipped with a 5-volt DC input in the event that the unit requires additional power, as in the case of a DVI source not outputting the proper amount of voltage.

High Definition Television Defined
HDTV (high definition television) is a rapidly emerging video standard that transmits large amounts of visual data (resolutions up to 1920 x 1200 and 1080P) using DVI (digital visual interface) connectors, resulting is crisp, highly defined visuals that resemble movies shot on 35mm film. Since 2000, DVD players, computers, televisions and monitors have been equipped with the 24-pin DVI connection ports. DVI is a transmitter of choice for HDTV because it is a purely digital interface that retains the integrity of the video signal through any transmission—even when sent over long lengths of cable. With DVI, there is no digital-to-analog or analog-to-digital conversion process that needs to take place before, during or after transmission. This streamlined, straightforward process makes DVI the current preferred interface for HDTV.

How it Works
Simply connect your HDTV to the Switcher’s DVI output. Then, using the four high quality DVI cables that come with the 4x1 HDTV Switcher, plug each one into the four source devices, then connect them to the Switcher’s DVI inputs. Once the source devices and the HDTV are powered on and connected, you simply switch between source devices using the RMT-4IR remote control or your own universal remote.

The 4x1 HDTV Switcher is HDCP pass-through.
