The VEEMUX SM-32X16-AV-LCD audio/video matrix switch routes audio and video input from 32 computers to 16 displays (projectors, Monitors, etc.) and speakers. This switch can drive standard VGA Cables, thus eliminating the need for external interfaces and coax Cable connections via BNC connectors.
Signals from a range of input sources can be distributed to various output devices. A single computer video output can be routed to one or more Monitors. Each video output is buffered from each input, ensuring signal integrity throughout the system. When switching ports, the audio automatically mutes until the video has been synchronized. The audio can also be muted on command.

NSI LIGHTING - Light Control Systems
NSI is ushering in a new era of microprocessor controlled stage lighting technology with these products. The powerful NSI digital product series provides advanced, flexible control for a variety of innovative applications. Because of their advanced design, these consoles feature many benefits found in today's personal computers. You can add programmable memory, scene masters and chase effects, all with the simplicity of a familiar two-scene console.
Used Video Switcher
Video switchers, also known as a video display controller (abbreviated to VDC) is essentially the key component of a video signal generator. This kind of vision mixer is used for generating a visual signal in computers, and in some cases an audio signal too, although this is just a secondary function. The video switcher first made its appearance in our homes in the first types of home computers, such as the old Commodores and Spectrums, and is now an integral part of video signal generator logic.
A video mixer cannot work alone however, as it needs support from various other parts of the computer to work. For example, pixel data is stored in the computerâ??s RAM, while character fonts are held in the ROM. Therefore, the video switcher chip will usually be totally integrated into the main computer, and so users will be able to see the video RAM it gives in the CPUs memory map. It can also act as a co-processor that acts independently, although this is not usually the case.
The video switcher is generally available in three different formats. Video shifters are the most basic type of production shifter, and take care of the video timing signals. These obtain data one byte at a time from the CPU, and use synchronization signals to produce a video signal. The CTRC video switcher reads data directly from the computerâ??s RAM, and this is then outputted either through a ROM or directly. Far more complex are video interface controllers. This kind of video switcher supports sprites and video RAM which is dedicated towards color attributes, thus making extremely high-resolution images possible.
