The Gefen TV 4x1 HD Switcher w/ Audio Decoding

The GefenTV 4x1 HD Switcher w/ Audio Decoding is ideal for anyone wanting 

to create Home Cinema systems using multiple HDMI audio/video sources. It 

offers an easy-to-use alternative to over-complicated Home Theater Receivers, 

while supporting 3DTV andthe latest Blu-ray audio features, or it can add HDMI 

connections and audio decoding to existing A/V Receivers that lack HDMI 

support.  It decodes multi-channel surround-sound formatted digital audio 

from up to four HDMI sources, from coax and optical S/PDIF digital audio 

sources, plus a stereo analog input.  Audio is output on six discrete analog RCA 

jacks, ready for any 5.1 channel power amplifier, or connects to the “External 

Processor” input on most existing A/V receivers. Dolby Digital 5.1, Dolby Pro 

Logic II, LPCM direct stereo and multi-channel surround-sound audio formats 

are supported with up to six (5.1) discrete channels. The front left and front 

right channels feature dual outputs for bi-amplification. Advanced audio pre-

processing insures an optimal surround sound signal, and a bright LCD display 

guides operations. RS-232 control allows connection to remote control or home 

automation systems, such as Gefen’s new GAVA automation system and Gefen 

PACS, with full feedback.

How It Works

Users can select audio from any one of four connected Hi-Def sources, both 

digital audio inputs and 2-channel analog audio. A Blu-ray player, gaming 

console, set-top box, DVD player, CD player and more can all be connected at 

the same time. If an HDMI source is selected, video is delivered in Hi-Def format 

to any HDTV display, and audio is delivered as 5.1 channel audio using standard 

RCA connectors. The HDMI output supports pass-through 3DTV making it ideal 

for future-proofing systems. Users can also pass-through audio using the digital 

and/or analog audio inputs, delivering it as up to 5.1-channel audio, enabling 

high quality surround-sound.  When an audio input is selected, the video from the 

previously-selected video source is still output to the HDMI output, allowing users 

to watch a video source while listening to a different audio source.  Users control 

all audio features using the IR remote or by front-panel buttons. An RS-232 port 

and 12V triggers allow interaction with any home automation system for added 

convenience.
