Designed to be standard for in-wall digital audio/video installations. System empowers to customize installation to create own ideal audio/video solution. Break-away flying leads and wall plates ensure flexible, efficient, high quality connections for all types of equipment. Source device (cable box, DVD player, video game system) will not have enough power dedicated to HDMI output. Cause voltage drop and video quality affected, or worse, there is no video at all. Voltage inserter solves problem by isolating power from source device, and it provides 1A of dedicated power to give crisp, clean signal that expected from high definition equipment, up to 1080p resolution.
