4 Inputs to 1 Output HDMI Switcher:
Let's start with the basic functions of your Key Digital

well as Audio. HDMI lets source devices (like your DVD player, Satellite /

HDMI 4x1
TM
Switcher functions as a true HDMI repeater to pass along
this information. Your switching connection is truly seamless!
