1. INTRODUCTION
The HDMI Repeater with Video Output is designed to convert thedigital signal from HDMI (or DVI + Coaxial) source to an analog NTSC
or PAL signal, with L/R stereo audio. As well as S-Video and Composite
Video outputs, it also provides an HDMI bypass output to deliver theoriginal signal, and a Coaxial output to send S/PDIF digital audio to anamplifier. The unit provides a convenient method of converting nonHDCP high definition content to standard 480i or 576i resolutions for
DVR or VCR recorders.

2. APPLICATIONS• HDMI to Composite Video or S-Video signal conversion• HDMI to NTSC/PAL system conversion• HDMI to SD resolution for recording/monitoring

3. PACKAGE CONTENTS• 1×HDMI Repeater with Video Output• 1×5 V/2.6 A DC Power Adaptor• Operation Manual

4. SYSTEM REQUIREMENTS

** For DVI input or output you will need to use an HDMI to DVI
adaptor or cable.
*** Analog L/R audio outputs are not available when the audio input
is Coaxial, please connect the analog audio from the source toyour amplifier or active speakers directly.
Note 2:•When the signal from an HDMI or DVI source is protected by
HDCP (High-bandwidth Digital Content Protection), the HDMI or
DVI display also needs to support HDCP to be able to show thecontent.
