SW A V Series Switchers 1 Chapter One Intr oduction About the Switchers Features.
Introduction, cont’d SW AV Series Switcher • Introduction 1-2 Intr oduction About the Switchers The Extron SW A V series (figure 1-1) is a family of video and/or audio switchers with a wide array of input and output configurations, video formats, and audio connections.
1-3 SW AV Series Switchers • Introduction Bandwidth — Bandwidth is 250 MHz (-3dB). This high bandwidth allows the switchers to switch all of the quad standard video formats with no loss of signal quality . All video models Input sensing — The switcher continuously monitors all inputs to sense when the input signal is active or inactive.
Introduction, cont’d SW AV Series Switcher • Introduction 1-4 External sync input and output connectors — Allow the switcher to use a black burst (genlock) signal to synchronize switching during the vertical interval. This ensures glitch-free switching among multiple timed sour ces.
1-5 SW AV Series Switchers • Introduction Audio follow — If the switcher is also a video model, audio can be switched with the corresponding video input.
