INTRODUCTION

Congratulations on your purchase of the GefenTV Home Theater Audio
Processor. Your complete satisfaction is very important to us.

GefenTV

GefenTV is a unique product line catering to the growing needs for innovative
home theater solutions. Gefen specializes in total integration for home theater
connectivity, while also focusing on going above and beyond customer
expectations to ensure you get the most from your hardware. Gefen invites you
to explore the distinct GefenTV product line and hope that you fi nd the solution
that fi ts your needs.

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 amplifi er,
delivering 25 watts per channel RMS. The audio can also be sent to an external
power amplifi er using the RCA connectors. The front-left and front-right channels
use bi-amplifi cation 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 fi 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.
