With the wide variety of signal types, both analog and digital, as well as the broad range of flatpanel and video projector displays and their respective resolutions, routing any given input to any given output or multiple outputs while preserving signal integrity can be a challenge. Matrix switchers, in configurations as simple as 2x2 or as complex as 64x64 and larger, have become essential in achieving fast and reliable signal delivery. Here’s a look at a gamut of matrix switchers for both large and small AV applications.

Marketed for large-auditorium-based presentations, the SMX offers advanced screen layer management and can be used alone, or linked together with others, for showing images on differently configured hard and/or soft display surfaces. In addition to the four primary outputs, presentation monitoring has been allocated a dedicated preview output. There are preset views for an operator to have greater control over how shows are executed.
