The MVX 44 VGA A is designed to route high resolution computer-video and stereo 
audio signals. Convenient 15-pin HD connectors are used for all computer-video 
input and output connections. Unbalanced stereo audio is input on 3.5 mm stereo 
mini jacks, while balanced or unbalanced stereo audio is output on captive screw 
connectors. Using pre-terminated cable assemblies, such as Extron's VGA with 
Audio Cables, eliminates crimping and makes installations faster and easier.

In addition, the MVX 44 VGA A comes standard with the QS-FPC¢â - QuickSwitch Front Panel Controller, which allows for touch-of-a-button input and output selection directly from the front panel. It can also be controlled through RS-232 serial control utilizing Extron's SIS¢â - Simple Instruction Set commands, the optional Extron IR 501 remote control, the optional Extron MKP 2000 or MKP 3000 X-Y remote control panels, or via a third party control system.
