1. Introduction

1.1. Introduction to MDV44A

MDV series Matrix switcher is a high-performance professional computer and audio
signal switcher that can be used for cross switching of multi computer and audio signal.
Independent DVI component and balance/unbalance I/O terminals make each
component signal transmit and switch separately; this design can reduce attenuation
of signal transmission to minimum and output the image and audio signal in
high-fidelity quality.

DVI series switcher mostly apply in broadcasting TV engineering, multi-media meeting
room, big screen display engineering, television education, command control center or
other fields. It supports A/V timing or separating switching function. With RS232
interface, it can be worked with PC, remote control system and any other far-end
control system devices.
