4K HDR 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 distributed across 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 Distribution Amplifier 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” can be enabled command to periodically reset input selection on CEC compatible connected displays. This unit provides an intuitive set of front panel controls with an OSD as well as RS-232 control options.
