Understanding Switcher Layers

•M/E 2 provides a “re-entry” output that flows into the PGM bank.

•Please note:

~On each M/E, the BG and PST buses comprise the background layer — the farthest layer upstream, and visually, the layer that’s behind Key 1 and Key 2.

~Key 1 is downstream of the BG and PST layer, but upstream of Key 2. Keys created on Key 1 are visually “over” the BG and PST layer, but “under” Key 2.

~Key 2 is the farthest layer downstream on an M/E. Keys created on Key 2 are visually “over” BG, PST and Key 1.

~Even if you swap key settings by pressing the {Swap Key Settings} button, the priority of the layers does not change.

•The PGM bank consist of Program (PGM) and Preset (PST) buses, and a single layer of keying (DSK). The bank provides Program, Preview and Clean Feed outputs. Please note:

~The entire PGM bank is downstream of M/E 1 and M/E 2 — visually on top of all effects created on the M/Es.

~The PGM and PST buses comprise the bank’s background layer — the farthest layer upstream in the bank, and visually, the layer that’s behind the DSK.

~The DSK is downstream of the PGM and PST layer, but upstream of the FTB (fade to black) function. Keys created on the DSK are visually “over” PGM and PST.

~FTB is the farthest function downstream in the switcher. This function enables you to fade the entire switcher (including DSK) to black

•In the default “priority” layering of the switcher when M/E 2 control is enabled, the M/E 1 bank is upstream of M/E 2, and M/E 2 is upstream of PGM. Thus, M/E 1 is visually behind, M/E 2 is in the middle, and PGM is visually on top.

However, using the Other Setup Menu (located on the main System Menu) you can change the priority of the two M/E banks using the {M/E Order} function. In Chapter 5, refer to the “Other Setup Menu” section on page 253 for details.
