3.	Select an input. Use the ISS’s size and center functions to adust the crop or
	aspect ratio output to fill the screen.

NIf the input source is a DVD, set the DVD player to output a 16:9 aspect ratio before sizing the image using the ISS’s size function to correct the aspect ratio. See “Setting up a DVD source”, below.

NWhen you are sizing and centering a letterbox movie video source, increasing the brightness on the ISS makes it easier to see the top and bottom of the active video.

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.

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 “Audio input connections” and
	“Audio 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.
