effective solution in the market to route high definition video sources plus multi-channel (up to 7.1-channel)
digital audio from any of the eight HDMI source devices to the remote displays at the same time. Through low
cost Cat-5/5e/6 UTP/STP cables, not only high quality video and audio can be transmitted to the display sites,
but also users can switch among eight HDMI sources using the push-in button or remote control. With single
power design at the source site, each remote module is easily installed without power supply. Furthermore,
the built-in IR extension function let users can control the HDMI source devices such as the Blu-ray Disc
player or satellite receiver at display site directly!

Features
State-of-the-art Silicon Image (Founder of HDMI) chipset embedded for upmost compatibility and
reliability
HDMI 1.2a/1.3c* compliant
HDCP compliant
Allows any source to be displayed on multiple displays at the same time
Allows any HDMI display to view any HDMI source at any time
Supports 7.1 channel digital audio
Supports default HDMI EDID and learns the EDID of displays
The matrix master can switch every output channels to any HDMI inputs by push-in button, IR remote
control, or RS-232 control
Allows controlling local HDMI sources such as DVD and TiVo by IR extender through control path at
remote receiver
Allows to control main matrix center through control line at remote receiver
Extends video signal up to 35m (115 feet) over CAT5e at 1080p and likely longer with better HDMI source
device, better grade HDMI display, and better quality solid CAT6 cable
Easy installation with rack-mounting and wall-mounting designs for master and receiver respectively
Fast response time – 2~5 seconds for channel switch
The length depends on the characteristics and quality of the cables. Higher resolutions and longer
transmission distances require low skew cables (<25ns/100m) for best performance. Unshielded
CAT6 with metal RJ-45 connectors is recommended.

SW1-SW8 for EDID/Audio
Note
1
If the HDTV shows video but without audio, please try to set audio mode to stereo.
2 Factory default setting of [SW1]-[SW8] is pin-1 at OFF [] & pin-2 at OFF [] for 1080p video and
surround sound audio.
3 If you encounter any unsolved audio/video output problem during system installation, please turn
any [SW1]-[SW8] to pin-1 at OFF [] & pin-2 at ON [] for safe mode to enforce the system output
up to 1080p video and stereo audio for system check. However, the safe mode cannot be initiated
if your HDMI™ source is set to enforce 1080p output. In this case, please reconfigure your HDMI™
source to all resolution output for troubleshooting.
4
Bypass means the matrix will maintain playing the original format of HDMI signals in video and
perhaps audio. By setting at this mode, the users may encounter compatibility issue among different
kinds of HDMI sources and displays. If you cannot get the audio and/or video output normally at the
system installation, please change the DIP switch setting to default mode or even safe mode to
verify the functionality of the device.
