Introduction
The Atlona 4 input HDMI switchers are a great product for homes with multimedia systems and not enough
HDMI input options. The Atlona switchers support an Audio Return Channel and a 100Mbps Ethernet port
for HDMI Ethernet Channel (HEC), reducing the amount of wires necessary for compatible systems. The
Atlona switcher gives you a high digital performance connection, between four sources and a video display,
without signal loss.
