INTRODUCTION
The AV-GM0673-S1 1x2 HDMI Splitter over Cat.X with HDBaseT-Lite, 4K2K, IR & RS-232 provides
the most flexible solution by which the high definition video and high quality audio can be
transmitted to different locations over a long distance. The devices are cascadable, allowing you to
extend HDMI compliant displays almost anywhere. The input HDMI source can be duplicated and
distributed to 1 HDMI enable displays through cost effective Cat-5/5e/6 cables with HDMI over
CAT.X receivers. For convenience, AV-GM0673-S1 is also equipped a local HDMI output for
monitoring. With the built in equalization, the input HDMI cable can be extended up to 20 meters
(66 feet) long under Full HD, and make the overall transmission distance superior than regular
HDMI splitters or matrix switches in the market.
FEATURES
●Support HDMI Deep Color & full 3D & 4K2K@30 (HDBaseT technology)
●Extend the transmission up to 60m (198ft) from the HDMI source at Full HD 1080p 36-bit and
40m (132ft) at 4K2K@30
●HDCP & EDID Bypass
●Auto equalization
●Support full frequency IR signal from 20KHz to 60KHz
●Bi-directional IR path
●Regenerates the HDMI signal
●DTS-HD Master Audio and Dolby TrueHD high bit rate audio support
●Pure unaltered uncompressed 7.1ch digital HDMI over Cat.X cable transmission
●Allows cascading
●Wall mounting housing design for easy and robust installation

NOTICE
1. If the DVI or HDMI device requires the EDID information, please use EDID Reader/Writer to
retrieve and provide DVI or HDMI display EDID information.
2. All HDMI over Cat.X transmission distances are measured using Belden 1583A CAT5e 125MHz
UTP cable and ASTRODESIGN Video Signal Generator VG-859C & VG-870B.
3. The transmission length is largely affected by the type of Cat-5/5e/6 cables, the type of HDMI
sources, and the type of HDMI display. The testing result shows solid UTP cables (usually in the
form of 330m bulk cables) can transmit a lot longer signals than stranded UTP cables (usually in
the form of fixed length patch cords). Shielded STP cables are better suited than unshielded UTP
cables. A solid UTP Cat-5e cable shows longer transmission range than stranded STP Cat-6 cable.
For long extension applications, solid UTP/STP cables are the only viable choice.
4. EIA/TIA-568-B termination (T568B) for category cables is recommended.
5. To reduce the interference among the unshielded twisted pairs of wires in Cat-5/5e/6 cable, one
can use double shielded STP cables to improve EMI problems, which is worsen in long
transmission.
6. Because the quality of the CAT5/6 cables has the major effect on how long the transmission limit
can achieve and how good is the received picture quality, the actual transmission range is
subject to one's choice of Cat-5/5e/6 cables. For desired resolutions greater than 1080i or
1280x1024, a Cat-6 cable is recommended.
7. If your HDMI display has multiple HDMI inputs, it is found that the first HDMI input [HDMI input
1] generally can produce better transmission performance among all HDMI inputs.
