Introduction

The Model MH4-4K adds multiple video outputs to the MediaHub platform. For 

demo systems that require multiple video sinks, the Model MH4-4K acts as its own 

1:4 distribution amplifier. Connect up to four HDMI sinks (televisions, soundbars, 

A-V receivers, etc.) to the player; each output provides identical 4K@60 video 

signal, and individual CEC control of the sink.
