3. OPERATING THE 8X4 MATRIX FOR HDMI Important Note The 8x4 Matrix for HDMI incorporates a 2x1 switch in front of each input on a traditional 4x4 matrix This allows for the connection of up to 8 different HDMI source devices with a maximum of 4 sources available for viewable at any one time Each of the 4 switched inputs on the 8x4 Matrix for HDMI are labeled as A and B Both A and B for each input cannot be active at the same time Example A Multiple outputs viewing the same input source Devices 1A DVD player amp 1B Cable STB Scenario Outputs 1 and 2 are both viewing input 1A DVD Action User viewing output 1 switches the input from 1A DVD to 1B STB Result Both outputs 1 and 2 will be switched to viewing 1B STB Example B Multiple outputs viewing separate input sources Devices 1A DVD player 1B Cable STB and 2A Video Game system Scenario Output 1 is viewing 1A and output 2 is viewing 2A Action User viewing output 1 switches the input from 1A DVD to 1B STB Result Output 2 is not affected by the change of 1A to 1B because it is viewing a source 2A on a different input Display information EDID from the displays attached to the 8x4 Matrix for HDMI need to be sent back to the input sources Please see page 10 for EDID management features and options HDMI 1 2 compliant HDMI 1 3 compatible HDCP compliant FEATURES Features e Switches any eight HDMI sourc
