Input #2 submenu

Rotate the horizontal Adjust () knob while in the Input #2 submenu to select the appropriate video format (RGB, RGBcvS, YUVi, YUVp, Betacam 50, Betacam 60, HDTV, S-video, composite video) for input 2. The default for input 2 is Betacam 50.

Input Phase submenu

For RGB (input 1 and 2), HDTV, and YUVp (input 2) input sources, the pixel phase adjustment feature is used to eliminate unwanted noise by setting the sampling rate of the input source. See the following note. Rotate the horizontal Adjust () or vertical Adjust () knob to adjust the pixel phase from 0 to 31. The default setting is 16.

Pixel phase is the timing of the USP 405’s sampling rate. Sampling at the optimum pixel phase results in less noise and a brighter scaled output.

Resolution and refresh rates submenu

The output resolution is defined for each input. Rotate the horizontal Adjust () knob while in this submenu to select one of the combinations of output resolutions and refresh (vertical scanning) rates.

Rotate the vertical Adjust () knob while in this submenu to select one of the available refresh rates. Selecting Lock enables the Extron Accu-RATE Frame Lock™ (AFL™) feature. Accu-RATE Frame Lock eliminates image tearing and other artifacts of scaling motion video by eliminating frame rate conversion. It exactly matches the output rate of the USP 405’s scaler to the frame rate of the input. Select this feature if you will be using motion video sources with a display that is capable of a variety of refresh rates.
