IN1508 Scaling Presentation Switcher 1 Chapter One Introduction About this Manual About the Switcher Features
Introduction, cont’d Introduction About this Manual This manual contains installation, configuration, and operating information for the Extron IN1508 Scaling Presentation Switcher (referred to in this manual as the “IN1508” or the “switcher”). • Chapter 1 identifies the switcher’s features. • Chapter 2 details how to install the switcher. • Chapter 3 describes how to operate the switcher from its front panel and use all of its features.

Introduction, cont’d Standard DVI cable DVI/DFP signals run at a very high frequency and are especially prone to bad video connections, too many adapters, or excessive cable length. To avoid the loss of an image or jitter, follow these guidelines: • Do not exceed 16.4 feet (5 meters) on the switcher’s input when using standard DVI cables. Extron’s IN9700 extension cable can be used to extend the length of the input cable. See “IN9700 cable”, below.
Audio outputs — The switcher provides an unbalanced line level signal that is identical to the input signal. This output can drive any line level compatible audio unit, or a local device such as powered speakers.
Introduction, cont’d Inverse 3:2 pulldown detection for NTSC video sources and 2:2 film detection for PAL video sources — This advanced film mode processing feature helps maximize image detail and sharpness for video sources that originated from film. When film is converted to NTSC video, the film frame rate has to be matched to the video frame rate in a process called 3:2 pulldown. Jaggies and other image artifacts can result if conventional deinterlacing techniques are used on film-source video.
Freeze mode — Provides a high quality still image for applications that require close examination of a specific video frame. Blank mode — Suppresses the output video image. Blank silences the R, G, and B video outputs but the switcher still outputs sync. This ensures that the output device does not lose sync lock. Blank mode operates for video and RGB signals that are processed by the scaling circuitry. On-screen displays are not blanked.

IN1508 Scaling Presentation Switcher 3 Chapter Three Operation Front Panel Controls and Indicators Remote Control Buttons Operations Optimizing the Video Optimizing the Audio Troubleshooting
Operation, cont’d Operation Front Panel Controls and Indicators All of the switcher’s controls are on the front panel (figure 3-1). Many controls are duplicated on the IR remote control (figure 3-8 on page 3-7). Front panel LEDs provide graphic indication of some of the basic system functions. For more complex tasks, such as system configuration, the switcher has a menu system that is operated by using the front panel or IR remote control buttons.
Input controls 2 Input buttons — The Input 1 through Input 8 buttons (figure 3-3) select the associated video input to scale and output. The switch can be a cut or a fade, depending on the switch mode; see “Fade Switch selection box”, on page 3-24. Audio always follows (switches with) the front panel video selection.
Operation, cont’d Output Rate selection 3 Output Rate button — The Output Rate button (figure 3-4) cycles through the available output screen resolutions. Use this button to select the “sweet spot” resolution of the connected video display device. The switcher defaults to a refresh rate of 60 Hz with each resolution selection using the Output Rate button. Eight IN1508 output resolutions are not available from the front panel.
Picture-in-Picture controls 4 PIP buttons — PIP ON SWAP Figure 3-5 — Picture-in-Picture buttons On button — The PIP On button toggles the PIP function on and off. If you press and hold the PIP On button while you apply power to the switcher, the switcher toggles the output signal type between RGB and progressive component video. If an RGB signal type (RGBHV, RGBS, or RGsB) was selected the last time the switcher was powered, the signal type switches to component.
Operation, cont’d Picture Controls buttons PICTURE CONTROLS CONT/ COL/ SIZE BRT TNT CENTER Figure 3-6 — Picture Control buttons 5 Picture Controls buttons — The Picture Controls buttons provide a shortcut to select individual or groups of image adjustments that are adjusted using the , , , and buttons ( 7 ). These adjustments are also available via the menu system. Center control button — The Center button selects and deselects the display centering adjustment.
8 Enter button — The Enter button: • Activates a highlighted submenu or function in the IN1508 main menu system. • Exits a slider-type status indicator bar control. • Saves a changed value in a selection box control. See “Main menu system”, on page 3-16, and “Picture adjustments”, on page 3-25, for details.
Operation, cont’d A/V Mute — The A/V Mute button switches the output to a blank screen and silences the audio output. The blank screen and muted audio are deselected when a new input is selected. Freeze — The Freeze button toggles the freeze feature on and off. Freeze stops the image at the moment you activate the feature and outputs a still image. Freeze is deselected when a new input is selected. 12 Menu buttons — The Menu buttons function identically to the front panel Menu buttons.
Color/Tint control button — The Color/Tint button selects and deselects the display color and tint adjustment status indicator bars. The adjustment range for both color and tint is from 0 to 127. The Color/Tint control affects only certain interalaced component video, composite video, and S-video, as shown in the following table.
Operation, cont’d Input selection operation Each of the eight inputs is assigned to one of two groups (see figure 3-9 on the next page): • Low resolution — Inputs 1 through 4 (and input 5 if it is configured as interlaced component video; see “Input 5 selection”, on page 3-18) • High resolution — Inputs 6 through 8 (and input 5 if it configured as progressive component video/HDTV; see “Input 5 selection”, on page 3-18) Input selection acts differently, depending on whether PIP mode is on or off: • • PI

Operation, cont’d Menu system operation Figure 3-10 shows a flowchart of the submenus in the main menu system. Each submenu leads to a series of submenus or to “slider” type status indicator bar controls that accomplish individual tasks or groups of tasks. In figure 3-10, and all other flowcharts in this chapter, solid lines indicate screen changes initiated by the operator. Dashed lines indicate screen changes that are the result of a timeout function.
Menu button — Press the front panel or IR remote control Menu button to activate the menu system or to back up one level from the currently selected submenu or selection. (For example, pressing the Menu button in the Picture submenu turns off the Picture submenu selections and the switcher displays the main menu only.
Operation, cont’d Selection box control The selection boxes (figure 3-11) show a list of possible selections. When you first activate the selection box control, the selected option is marked with a . Use the front panel or IR remote control and buttons to move the to highlight other options. Highlighting a different option by moving the does not automatically select that option. You must push the front panel or IR remote control Enter button to change the selection.
Many status indicator bar controls can be activated in three ways (figure 3-12): • By navigating to the status indicator bar via the menu system • By pushing one of the front panel Picture Control buttons (such as Color/Tint) • By pushing one of the IR remote control picture control buttons (such as Color/Tint) Use the status indicator bars as follows: 1. If necessary, select the input that you want to adjust by pressing the appropriate input button. 2. For menu system operation: a.
Operation, cont’d Main menu system The main menu includes the following submenus: • Input submenu — Size, centering, and aspect ratio • Picture submenu — Image quality adjustments • Output submenu — Resolution, refresh rate, sync, and signal format • Audio submenu — Input audio volume and audio delay • Advanced submenu — Advanced options Input submenu Figure 3-13 is a flowchart that shows an overview of the Input submenu, its available selections, and their available settings.
Center selection The Center selection displays two status indicator bars that show, and allow you to adjust, the horizontal and vertical position of the main or picture-in-picture output on the monitor. If the PIP feature is turned off (the front panel PIP On LED is unlit), Center adjusts the position of the main window. If the picture-in-picture feature is turned on (the front panel PIP On LED is lit), Center adjusts the position of the PIP window.
Operation, cont’d Advanced screen The Input submenu’s Advanced settings are a comprehensive set of adjustments to optimize the switcher for non-standard video inputs. Most users do not encounter such signals. For those users who do, the switcher automatically adjusts these settings. The switcher’s automatic adjustments are adequate for most inputs. The Advanced screen provides a submenu of advanced selection options: active pixels, active lines, phase, horizontal and vertical start, and total pixels.
Brightness status indicator bar The Brightness status indicator bar shows, and allows you to adjust, the brightness setting for the selected input. Brightness adjusts the light intensity of the image on the screen. Use the front panel or IR remote control and buttons to adjust the brightness control through a range of 0 to 128. The default setting is 64. Contrast status indicator bar The Contrast status indicator bar shows, and allows you to adjust, the contrast setting for the selected input.
Operation, cont’d Output submenu Figure 3-15 is a flowchart that shows an overview of the Output submenu, its available selections, and their available settings. Use the front panel or IR remote control and buttons to highlight the desired selection and press the Enter button. Timeout No menu display Menu Menu INPUT Timeout Menu PICTURE Timeout Menu Menu OUTPUT Enter Resolution Enter Menu Timeout Press Enter to select a change.
Resolution selection box The front panel Output Rate button can also be used to select most resolutions, with the following exceptions: • 852 x 480 • 1440 x 900 • 1400 x 1050 • 1680 x 1050 The Resolution selection box identifies the currently selected output resolution and allows you to select a different output resolution. The table at right defines the combinations of resolutions and refresh rates that the switcher can output. The default resolution is XGA.
Operation, cont’d Signal Type selection box The Signal Type selection box identifies the currently selected output signal format (RGBHV, RGBS, RGsB, or progressive component video [Y, B-Y, R-Y]) and provides the ability to select a different type. To select a different sync type, use the front panel or IR remote control or button to highlight the desired sync type and press the enter button. The default setting is RGBHV.
Audio Delay selection box The Audio Delay selection box provides the ability to turn audio delay on and off. Audio delay compensates for the latency period that is inherent in deinterlacing NTSC, PAL, and SECAM video by delaying the audio output to match the video output. Use the front panel or IR remote control and buttons to select On or Off. The default is On.
Operation, cont’d Swap selection The Swap selection toggles the primary and secondary inputs between the main image and the PIP window. Select swap by highlighting the Swap selection and pressing the Enter or button. Repeatedly press the Enter or button to toggle between the main and PIP windows. Press the , , or button to deselect Swap, or allow the menu timeout (from the final button push) to clear the on-screen displays.
Performing a system reset from the front panel The front panel reset is identical to the Esc zXXX SIS command (see chapter 4, “Serial Communications”) and the system reset that is available through the reset system (see “Reset selection box” earlier in this chapter). But the front panel reset does not require a connected computer or a connected monitor to view the onscreen displays.

Operation, cont’d Window Centering display — This display consists of two status indicator bars that show, and allow you to adjust, either the position (centering) of the main image or the position of the PIP window, depending on whether the PIP feature is off or on. PIP is off — Center adjusts the horizontal and vertical position of the main image on the monitor. The adjustment range depends on the input rate applied and the output resolution selected.
• Color/Tint: Color increases and decreases the color intensity of the picture. Tint is a relative measure of the amount of white in a given color and adjusts the picture’s color toward red or green. The color adjustment is also available by using the front panel or IR remote control to select Menu > Picture > Color in the main menu system (see “Color status indicator bar”, on page 3-19).
Operation, cont’d Front panel security lockout The front panel security lockout limits the operation of the IN1508 from the front panel. When the switcher’s front panel is locked out, all of the front panel image adjustment functions are disabled. You can still select inputs. To toggle executive mode on or off, simultaneously press and hold the Color/Tint and Center buttons (figure 3-21) for approximately 2 seconds. Release the buttons.
The ideal resolution must lie within the compatible range of the display. For example, some 27” to 36” presentation monitors are limited to input signals in the 30 kHz to 50 kHz range. Check the Direct View Display Cross Reference and the Projector Cross Reference on the Extron Web site (www.extron.com) for the most up-to-date compatible ranges of most displays.

Input submenu’s Advanced selections Figure 3-22 shows the selections that are available from the Input > Advanced screen. The switcher automatically adjusts for different input and output modes. However, if the input signal has slightly different timing or is non-standard, some settings may need to be manually adjusted.
Operation, cont’d Vertical Start Total Lines Blanking Area Active Area Active Lines Horizontal Start Active Pixels Total Pixels Figure 3-23 — Advanced input settings • Total pixels (RGBHV/RGBS/RGsB and progressive/HDTV component only) — The total number of pixels per line, including the blanking on both sides of the input active area (active, horizontal sync width, back porch, and front porch).
Horizontal Start and Vertical Start status indicator bars The input start controls adjust where the electronic scaling process takes effect. The input start and active area should be manually adjusted, if necessary, to match the input video signal, framing the active area of the input signal. If the start is set incorrectly, the switcher may add blank borders on the leading edges (top or left side) or it may crop the active area on the trailing edges (bottom or right side).
Operation, cont’d Similarly, if the vertical start adjustment is set to less than the amount of actual blanking, the IN1508 starts scaling before the first line of the active image. This early scaling results in a blank border on the top and cropping on the bottom, and looks as if the image is shifted down. Adjust the H Start status indicator bar to shift the switcher’s starting point horizontally on the screen. Adjust the V Start status indicator bar to shift the starting period vertically on the screen.
default capture rate to the specified input frequency. It then maintains the aspect ratio based on the difference between the input active area and the output resolution (active area) by inserting blank borders around the images. If, however, you want to fill the entire monitor, you can adjust the input aspect ratio by slightly changing the number of active pixels and active lines to stretch the image. You may also need to adjust the number of total pixels.
Operation, cont’d Total Pixels status indicator bar There are several methods to determine the correct value to use in the total pixels variable. Usually, the best method is to use the input signal specifications. For some input sampling rates, the switcher’s setting can result in fine vertical lines (figure 3-26). Blanking Area Active Area Total Pixels Figure 3-26 — Incorrect total pixels variable These lines appear as fuzzy vertical bars when an alternating pixels pattern is applied.
Optimizing the Audio Each individual input audio level can be adjusted within a range of -53 dB to +9 dB, so there are no noticeable volume differences between sources and for the best headroom and signal-to-noise ratio. Adjust the audio gain and attenuation as follows: 1. Connect audio sources to all desired inputs and connect the audio output to an output device such as an audio player. See “Audio connections”, in chapter 2, “Installation”. 2.
