SW RGB and YUV A Switchers 1 Chapter One Introduction About the Switchers Features
Introduction, cont’d Introduction About the Switchers The Extron SW RGB and YUV A series (figure 1-1) is a family of six RGB video switchers and one component video switcher, some with audio, in an array of input and output configurations.
Features Audio switching models Inputs — These switchers input 2, 4, or 6 stereo audio signals, balanced or unbalanced, on 3.5 mm, 5-pole captive screw terminals. Outputs — The selected audio input is buffered and output, balanced or unbalanced, on a 3.5 mm, 5-pole captive screw terminal. Audio gain/attenuation — Users can set the input level of audio gain or attenuation (-18 dB to +24 dB) via the RS-232 link or from the front panel, to be compatible with a wide range of line level (from -20 dBV to +4 dBV).
Introduction, cont’d All models Bandwidth — Bandwidth is 350 MHz (-3 dB). This high bandwidth allows the switchers to switch all of the high-resolution video signals with no loss of signal quality. Input signal sensing — The switcher continuously monitors all inputs to sense when the input signal is active or inactive. The switcher reports changes in the status of each input (active to inactive or inactive to active) on the RS-232 port.

Installation, cont’d Installation Installation Overview Install an SW RGB or SW YUV A Series switcher as follows: 1 Turn off the input and output devices, and unplug their power cables. 2 If desired, mount the switcher in a rack, under furniture, or through furniture. See Mounting the Switcher below. 3 Connect the input and output devices to the switcher (see Cabling and Rear Panel Views on page 2-6).
Use 2 mounting holes on opposite corners. False front panel uses 2 front holes.

Installation, cont’d Under furniture mounting the switcher The SW2 switcher models can be mounted under a table or other horizontal surface with an optional Extron under-desk mounting kit (part #70-077-01). The SW4 and SW6 switcher models can be mounted under a table or other horizontal surface with an optional Extron 1U under-desk mounting kit (part #70-222-01). SW2 models 1.
3. Drill 1/4" (6.4 mm) deep, 3/32" (2 mm) diameter pilot holes in the table or desk at the marked screw locations from the underside/inside (concealed side) of the furniture, where the switcher will be located. 4. Insert the four wood screws into the pilot holes. Fasten each screw into the installation surface until just less than 1/4" of the screw head protrudes. 5.
Installation, cont’d Slide the switcher up and down or back and forth in the mounting brackets until the face of the switcher is at the desired height. Tighten the screws that secure the bracket in place. 5. If the screws are inaccessible to a screwdriver: a. Mark the location of the brackets relative to the screws. b. Remove the switcher from the underside of the surface. c. Tighten the screws. d. Replace the switcher on the underside of the surface (step 4).
Inputs 1 RGB and component video inputs — RGB models — For each input, connect an RGBHV, RGBS, RGsB, RsGsBs, or component video source to these BNC connectors. Connect the cables as shown in figure 2-8. SW6 YUV A — For each input, connect a component video, RGsB, or RsGsBs source to one of these BNC connectors. If you are not switching digital audio, you can use the Digital Audio input BNCs ( 3 ) for the composite sync plane of RGBS video inputs. Connect the cables as shown in figure 2-8.
Installation, cont’d The audio level for each input can be individually set, via the front panel or under RS-232 control, to ensure that the level on the output does not vary from input to input. See chapter 3, Operation, and chapter 4, Remote Control for details. 3 Digital audio input connections (SW6 YUV A only) — Each input has a female BNC connector for a digital audio input. If you are not switching digital audio, you can use this connector to input the composite sync plane of RGBS video.
Remote connection 7 Remote connector — Connect a host device, such as a computer or touch panel control, or a remote contact closure device to the switcher via this 9-pin D connector (figure 2-11) for remote control of the switcher. See chapter 4, Remote Control, for definitions of the SIS commands, details on how to install and use the control software, and information on how to make a remote contact closure device.

SW RGB and YUV A Switchers 3 Chapter Three Operation Controls and Indicators Switcher Operations Optimizing the Audio (SW2, SW4, and SW6 RGBHV A only) Troubleshooting — If No Image Appears
Operation, cont’d Operation Controls and Indicators The SW RGB or SW YUV A family of switchers have 2, 4, or 6 input buttons and LEDs on the front panel. Audio models also have front panel configuration controls and LEDs. All models have an Auto/Manual mode selection switch on the rear panel. Figure 3-1 shows the front panel of an SW2 RGBHV switcher. Figure 3-2 shows the front panel of an SW6 RGBHV A switcher.
Audio controls and indicators 3 Audio configuration/save button and LED — The Audio button and LED enable the user to view and/or change the current audio level setting for each input. See Audio gain and attenuation in this chapter. 4 Down ( ) button and LED — The button is used to decrease the audio level for a selected input. The LED flashes each time the button is pressed to indicated a 1 dB decrease in the audio level. See Audio gain and attenuation in this chapter.
Operation, cont’d Switcher Operations The following paragraphs detail the power up process and provide sample procedures for selecting an input and viewing and adjusting the audio level. Power Plug in the switcher. On all switcher models, power is automatically applied when the power cord is connected to an AC source. When AC power is applied, the switcher performs a self-test that blinks the front panel LEDs during the test.
2. Press and hold the Audio Conf/Save button until the Conf/ Save LED begins to blink, then release the Conf/Save button. The +dB and –dB LEDs display the polarity (+ or –). The lit +dB LED indicates a positive (gain) level. The lit –dB LED indicates a negative (attenuation) level. Both LEDs lit indicate 0 dB. Press and hold. B CONF/SAVE Conf/Save blinks. Release the button. On the SW4 RGBHV A and SW6 RGBHV A only, the input 1 through 4 LEDs display the approximate audio level for the selected input.
Operation, cont’d If the +dB and –dB LED are both lit they indicate 0 dB. Otherwise, you can determine the exact gain or attenuation using the following procedure. a. If one or more input LEDs are lit AND the +dB LED is/are lit, press and release the button repeatedly until the highest-numbered lit input LED goes out. Count the button presses. In this example, assume a value of +8 dB. It will take three presses of the button for the Input 1 LED to go out.
Audio level reset — single input Reset the audio level for an input to 0 dB as follows: The switcher must be in normal (manual) mode. 1. Press and release an input button to select an input. 2. Press and hold the Audio Conf/Save button until the Conf/Save LED begins to blink, then release the Conf/Save button. 3. Press and release the Input LEDs go off. 4. Press and hold the Audio Conf/Save button until the Conf/Save LED goes and LEDs go off, and the selected Input LED lights. off. The and buttons.
Operation, cont’d Troubleshooting — If No Image Appears 3-8 1. Ensure that all devices are plugged in and powered on. The switcher is receiving power if the front panel Power LED (if equipped) is lit. 2. Ensure an active input is selected on the switcher or that the switcher is in autoswitch mode. 3. Ensure that the proper signal format is supplied. 4. Check the cabling and make corrections as necessary. 5. Call the Extron S3 Sales & Technical Support Hotline if necessary.
