Front Panel Security Lockout (Executive Mode 1)
The front panel security lockout limits the operation of the IN1508 from the front panel.
When the front panel of the switcher is locked out, all of the front panel image adjustment
functions are disabled. You can still select inputs.
To toggle executive mode 1 on or off, simultaneously press and hold the Color/Tint and
Center buttons (figure 29) 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 press 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 scaling and compression functions of the DVD player
defeat 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 setup or action menu of the DVD player 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
