1. INTRODUCTION

This 4K UHD Switching Splitter with HDCP 2.2 is an advanced solution

providing high performance audio and video support including HDR

and other features defined by the HDMI 2.0a specification. 4K UHD HDMI

video sources, up to and including 4K@60Hz (4:4:4, 8-bit) as well as 10/12-

bit sources with HDR, are able to be passed along to the 8 outputs. Pass-

through of multiple digital audio formats such as LPCM 7.1, Bitstream and

advanced HD Bitstream with audio sampling rates up to 192kHz are also

supported. An independent HDCP management engine for each output

ensures stable HDCP performance.

This splitter also includes a special“Group Mode” which allows the unit

to function as two independent 1×4 splitters. When Group Mode is

enabled, each of the 2 HDMI inputs are routed to their own discrete set of

4 outputs.

When a mixture of displays with different specifications are connected,

each output can be configured to scale 4K to 1080p or apply colour space

conversion (4:4:4 to 4:2:0), as appropriate. Support for the CEC “active

source” command to periodically reset input selection on CEC-compatible

connected displays is also included. This unit provides an intuitive set of

front panel controls with an OSD as well as RS-232 control options.
