4 HDTV Sources + 1 HDTV Display = High Definition Convenience and Ease

The Gefen EXT-HD-441A 4x1 HD Digital Audio Switcher enables effortless source switching using a single high definition display. A simple and reliable solution, the 4x1 HD Digital Audio Switcher links any four HDTV sources with digital audio (DVD players and satellite set tops) to one HDTV display. It eliminates the need to disconnect then reconnect multiple HDTV sources, saving time by providing a fundamental tool that brings it all together behind the scenes. When all five devices (the display plus the four sources) are connected to the EXT-HD-441A switcher and powered on, you simply select which source you want to view on the display using the Switcher, the IR remote that comes with it or any universal remote you program to work with the Switcher.

Fully HDCP Compliant
HDCP (high definition content protection) is a standard encoded into the video signal to prevent it from being pirated. If a source device is HDCP coded and is connected to a HDTV display or projector without the proper HDCP decoding mechanism, the picture is relegated to “snow” or in some cases, very low (480P) resolutions of the images. In order to see HDTV with HDCP compliance, the source, the display and any device in between must be equipped with DVI connections that can enable HDCP decoding, such as the 4x1 HD Digital Audio Switcher.

To use with HDMI (high definition multimedia interface) equipment, Gefen supplies DVI to HDMI Adapters for the video only.

How the EXT-HD-441A works:

Simply connect your display to the Switcher’s DVI output and your digital audio device to the digital output. Then connect the four sources to the Switcher’s HDMI inputs using the HDMI cables and TOS link cables that come with the Switcher. Once the sources, the Switcher and the display are all powered on and connected, you simply select which source you want to view and listen.
