Overview
With more and more HDMI devices entering the Home Theater
market, the need for simultaneous access to different HDMI A/V
sources is becoming increasingly important. Now, the VS481A
HDMI Switch offers an easy and affordable way to add HDMI
capabilities to your home theater system by allowing you to
switch easily between up to four HDMI A/V sources that are
connected to your HDMI display.
With four HDMI A/V input ports, the VS481A HDMI Switch allows
you to connect four HDMI devices (such as an HD camcorder or
satellite box, HD-DVD player, hi-def Blu-ray player, home theater
PC, stand-alone streaming media player, or gaming console) to
your HDMI monitor, display, projector or TV at the same time. The
remote control and convenient front panel pushbuttons allow you
to quickly and easily toggle between A/V sources, while the front
panel LEDs indicate the source device at a glance.
For your convenience, the VS481A has a single input port
mounted on the front panel for connecting mobile or temporary
devices, such as digital cameras, while your permanent device
connections are out of sight on the rear of the unit.
Furthermore, for complete system and install integration, RS232
control is standard through the VS481A’s built-in bi-directional
RS-232 serial remote port that allows the switch to be controlled
through a high-end controller, PC, and/or home automation /
home theater software package.
