Input 1 can only input composite video, and Input 3 can only input S-video, no other video types are selectable for these inputs. Only inputs 2 and 4 offer selectable video types. From the Input Configuration menu, pressing the Next key repeatedly will display submenus with the input video types for Inputs 2 and 4. The SDI input (if any) can be assigned to any input from the Input Configuration submenus.

Input 2 Video Type

Rotate either the Adjust horizontal () knob or Adjust vertical () knob while in the Input 2 submenu to select the appropriate video format (composite, S-video, component) for input 2. The default is component video.

Input 4 Video Type

Rotate the Adjust horizontal () knob while in the Input 4 submenu to select the appropriate video format (RGBS, RGBcvS) for input 4. The default is RGBS.

SDI input (SDI IN)

Rotate either the Adjust horizontal () knob or Adjust vertical () knob while in the SDI Input submenu to select the input # for the SDI input. The SDI input can be assigned to inputs 1, 2, 3, 4, or none (*). The default is none.

After the SDI input is no longer assigned to an input, either because it has been assigned to a new input or is set to none, the input reverts back to the last video type that was assigned to it.
