• Model: SB-4144

The SB-4144 has (4) individual inputs and (4) individual outputs located on the back panel with a video bandwidth from 310MHz to 380MHz.

The SB-4144 VGA and Audio matrix switch is ideally suited for full HD (High Definition) LCD Television or Plasma display monitor applications. Functional manual control is achieved through push buttons located on the front panel with a single line LED display. External functional control is achieved through a RS-232 connection or through the IR remote control. The RS-232 connection allows functions to be controlled by third party controller. A Windows based control software package is included to provide complete control from a PC.

When using the SB-4144 VGA and Audio Matrix Switch, a one-to-many or many-to-one connections can be established. You can easily connect any input device to any output device. You can also establish a single input device to many output devices or any combination, eliminating the need to constantly reroute video/audio input and output cables. The SB-4144 is useful for matrix signals from VGA source devices (such as: Personal computer, Set Top Box, and Satellite Receivers, etc.) to VGA destination devices (such as LCD Monitors, VGA Monitors, Plasma LCD TV, VGA Projectors, etc.).
