Page 8: About The Switchers
Introduction, cont’d About the Switchers The Extron SW AV 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. The switchers route S-video (luminance (Y) and chrominance (C)), and/or composite video, and/or unbalanced audio on RCA connectors, and/or balanced or unbalanced audio on captive screw connectors. -
Page 9: All Video Models
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. -

(A) models only) — Each input has a 3.5 mm, 5-pole captive screw connector for balanced or unbalanced stereo audio input. Connectors are included with each SW AV Series switcher, but you must supply the audio cable. See figure 2-4 to wire a connector for the appropriate input type and impedance level. - Page 17 • If the stripped section of wire is shorter than 0.2”, wires can be easily pulled out even if tightly fastened by the captive screws.

Page 18: Remote Connection
External sync connection When the switcher switches between inputs, the resulting change in image should be glitch-free, or clean. Video models of the SW AV Series switcher can use an external signal to synchronize switching during the vertical interval. Without the external sync locking feature, switching between inputs can result in a brief rolling (sync loss) or a brief change in the picture size. -
Page 19: Power Connection
This type of video camera is capable of synchronizing with the external timing source for video editing applications. If no external sync timing source is connected to the switcher, switching occurs immediately after a front panel, RS-232, IR, or contact closure switch command.

Page 32: Executive Mode (Front Panel Security Lockout)
Operation, cont’d Executive mode (front panel security lockout) Audio switchers have an executive mode that limits the operation of the SW AV switcher from the front panel. When the switcher is in executive mode, the I/O button (video/audio/video and audio selection), toggling between autoswitch and normal mode, and all of the front panel audio gain and attenuation functions are disabled. -
Page 33: Troubleshooting - If No Image Appears
Ensure an active input is selected on the switcher or that the switcher is in autoswitch mode. Ensure that the proper signal format is supplied. Check the cabling and make corrections as necessary.
