The GefenTV Home Theater Audio Processor  
The GefenTV Home Theater Audio Processor is a powerful yet very compact  
solution for all your audio/video needs.  
The GefenTV Home Theater Audio Processor provides pass-through connection  
for a Hi-Def source to two mirrored HDTV displays using HDMI features  
supporting 1080p full HD, Deep Color, Lip-Sync, Dolby TrueHD, DTS-HD MA,  
and 3DTV pass-through. The audio from both the HDMI and coax inputs is sent  
to the coax and optical outputs as compressed AC-3 digital audio and to separate  
six-channel audio on the RCA and binding post connectors. Up to 5.1 channels of  
LPCM, Dolby Digital, and Dolby Pro Logic II is decoded on the output.  
Speakers can be connected to the binding posts using the built-in amplier,  
delivering 25 watts per channel RMS. The audio can also be sent to an external  
power amplier using the RCA connectors. The front-left and front-right channels  
use bi-amplication to enhance the sound quality.  
The Home Theater Audio Processor features an easy-to-read LCD display with  
extensive features such as individual control of speaker size, distance location,  
and volume up/down. Control is available using the front panel push buttons or  
using the included IR remote and RS-232 control.  
How It Works  
Connect the GefenTV Home Theater Audio Processor to the Hi-Def source using  
the supplied HDMI cable and coax cable. Connect up to two (2) HDTV displays  
or AV receivers to the Audio Processor HDMI outputs. Connect an optical and  
a coax cable from the Audio Processor digital audio outputs to an AV receiver.  
Use the binding posts to connect up to ve speakers. The sub-woofer must be  
a powered version and is connected to the RCA connector allocated for the sub.  
Connect the included 24V power supply to the Audio Processor and push the  
power button to turn on the Audio Processor. Apply power to the Hi-Def source  
and HDTV Display(s) and/or AV receivers.
