1. INTRODUCTION
This HDMI Repeater with Video Output is designed to convert digital
HDMI (or DVI plus Coaxial) sources into SD analog video (NTSC or PAL)
with analog stereo audio. On the input side, an HDMI port and digital
coaxial audio input are provided. For output, composite and s-video
ports plus stereo RCA connections are provided to handle the down-
converted analog signal. Additionally, HDMI and coaxial bypass
outputs are provided to let the original signal continue on to a digital
display or amplier. This unit provides a convenient method to convert
non-HDCP high-denition content to standard 480i or 576i resolutions
for monitoring or recording with analog equipment.
2. APPLICATIONS
• HDMI/DVI to Composite Video or S-Video signal conversion
• HDMI/DVI to NTSC/PAL system conversion
• HDMI/DVI to SD resolution for recording/monitoring
3. PACKAGE CONTENTS
• 1×HDMI Repeater with SD Video Output
• 1×5V/2.6A DC Power Adapter
• 1×Operation Manual
4. SYSTEM REQUIREMENTS
• HDMI source equipment such as a media player, video game
console or set-top box.
• Composite or S-video receiving equipment such as a TV, VCR or
broadcast monitor.

2
5. FEATURES
• HDMI 1.2, DVI 1.0 and HDCP 1.x compliant
• Supports a wide range of HD and PC input resolutions up to
WUXGA@60Hz (RB) and 1080p@60Hz (8-bit)
• Converts and scales the HDMI input signal to composite and s-video
(NTSC or PAL) output with an unscaled HDMI bypass output
Note: HDCP encrypted sources can’t be output over the analog
ports and will be blanked out.
• HDMI audio extraction to digital coaxial (LPCM 2.0 & Bitstream) and
analog stereo RCA outputs (LPCM 2.0 only)
• Automatic embedding of the digital coaxial audio source into the
HDMI output and analog outputs when a DVI-D video source is used
Note: Analog audio output will be muted if the source is in Bitstream
format.
• Coaxial audio input and output supports Bitstream and LPCM 2.0
digital audio
