Chapter 2: Overview
2. Overview
2.1 Introduction
HDMI Matrix Switches from Black Box support sharp, highly defined video in HD
resolutions of up to 1080p—with a bandwidth of 6.75 Gbps.
Any input can be routed to any output, or the same input can be routed to all
outputs or any combination, eliminating the need to manually move various cables
to display HDMI video from different sources on different screens. An input source
LED tells you at a glance each output you’ve selected.
The switch sets up in seconds and is easy to use. Control using front-panel
buttons, the included IR remote controller, or an RS-232 connection linked to a
Crestron®, AMX®, Control4®system, or any third-party computerized software/
hardware control system. The switch even comes with an RS-232 serial cable for
quick setup.
The switch also has an IR signal extension port (and includes an IR extender
receiver). Once plugged in, the receiver enables you to use the IR remote
controller to switch ports on the unit from another room—up to 984 feet
(300 m) away.
Four models are available:
• AVSW-HDMI4X4: (4) HDMI inputs, (4) HDMI outputs
• AVSW-HDMI2X4: (2) HDMI inputs, (4) HDMI outputs
