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.
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.

Secure the switcher to the rack using the supplied machine screws. Furniture mounting the switcher The SW AV switcher models can be mounted under a table or other horizontal surface with an optional Extron MBD 129 Through-Desk Mount Kit, part #70-077-02.
1U enclosures, but have more or fewer input connectors to accommodate the different configurations they provide. The two switchers shown have all of the connector types that are available in the SW AV product family covered in this manual.
(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.

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.
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. Monitor SW 12AV RCA...

Operation, cont’d Front Panel Controls and Indicators The family of SW AV switchers have a wide variety of input buttons and other controls and LEDs that vary with the number of inputs and whether the switcher has video, audio, or both. Not all switchers have every control or indicator described in this chapter.

Input 1 through 4, 6, 8, or 12 LEDs — The input LEDs identify the selected input. On models that switch both video and audio, if audio is broken away, the selected video input is indicated by a steadily lit input LED and the selected audio input is indicated by a blinking input LED.
Auto(switch) button — The Auto button is used with the Mode button to select autoswitching mode. See Switch mode in this chapter. This button is a secondary function of the Input 3 button.
An input can be selected for output using the front panel buttons. In switchers with both video and audio, the audio input can switch with the video input (audio follow) or either can be switched separately (audio breakaway). Select an input as follows: SW AV Series Switchers •...
(Video AND audio switchers) Select to switch video, audio, or both by pressing the I/O button. Select the desired input by pressing the associated input button. Observe that the LED for the selected input lights or blinks (audio breakaway (Video AND audio switchers)).
Operation, cont’d Video switchers must be in normal (manual) mode. To select video only for the switch, if necessary, press and release the I/O buttons until the Video LED lights and the Audio LED is off. Press and release the input 4 button. The input 4 LED lights. The video on input 4 is now selected for output.

To reset the audio level for an input to 0 dB, select the input: Video switchers must be in normal mode. (Video AND audio switcher) Select to switch both video and audio or audio only by pressing the I/O button.
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.
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.
