Setting Up A Dvd Source; Optimizing The Audio - Extron electronics ISS 506 User Manual

3. Select an input. Use the ISS's size and center functions to adust the crop or
aspect ratio output to fill the screen.
N If the input source is a DVD, set the DVD player to output a 16:9 aspect ratio
N When you are sizing and centering a letterbox movie video source, increasing
4. If the input source is RGB, use the horizontal and vertical detail adjustments
to increase the sharpness.
5. For S-video and composite video inputs, set the ISS to output blue-only
video and to output the Color Bars test pattern. Using the blue Color Bars as
a reference, use the ISS's color and tint controls to adjust the video's color and
tint.
6. For RGB video inputs, set brightness and contrast levels. See "Adjusting the
picture", earlier in this chapter.
6. Save this setting into one of the user memories using the User Presets menu.

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 ISS.
All sizing adjustments to correct aspect ratio should be done using the ISS.
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.

Optimizing the Audio

Each individual input audio level can be adjusted within a range of -18 dB to
+24 dB, so that 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 outputs to
output devices such as audio players. See "Input connections" and "Output
connections" in chapter 2, "Installation." For best results, wire all of the
inputs and the outputs unbalanced.
2. Power on the audio sources, the switcher, and the audio players.
3. Switch among the inputs (see "Selecting an input to be the preview output
and switching it to the program output", earlier in this chapter), listening to
the audio with a critical ear or measuring the output audio level with test
equipment, such as a VU meter.
4. As necessary, adjust the audio level of each input (see "Audio Level
submenu", earlier in this chapter) so that the approximate output level is the
same for all selected inputs.
