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 on-screen display shows Front Panel Locked or Front Panel Unlocked to
indicate the mode. The on-screen display also shows Front Panel Locked if you
push a locked out button.

Optimizing the Video
Setting up a DVD source
To get the best results when using a DVD as a video source, Extron recommends
that the DVD player itself be set up to output an aspect ratio of 16:9 and not 4:3.
Because all DVDs are mastered as 16:9, having them set up for anything else causes
the player to internally scale and compress the signal. The DVD player’s scaling
and compression defeats the advantage of having 3:2 pulldown detection in the
IN1508.
All sizing adjustments to correct the aspect ratio should be done using the IN1508.
To change the output aspect ratio of most DVD players:
1. Enter the DVD player’s setup or action menu while the disc is stopped.
2. Select the 16:9 aspect ratio.
Resolution and refresh rates
Resolution and refresh rate are probably the most crucial variables for optimum
image quality. Every display has an optimal or native resolution and an optimal
refresh rate. These vary, depending on:
• The type of display technology
• Whether the display has a fixed number of pixels (a native resolution)
• The size of the pixels
• The size of the display or screen
• The distance of the viewer from the screen
For best results, set the switcher’s output resolution and refresh rate to match the
capabilities of your display.
