![]() ![]() Program and Preview are selected by the operator in the crosspoint area and then taken to air by the transition area. The transition area is the next aspect of the Mix Effect. This allows for Technical Directors to comfortably push buttons on the bottom row of an M/E any time, knowing that they are only affecting the Preview bus. On switchers with a M/E, the Preview row is always on the bottom, and the Program row is always above it. By using the Shift button you are allowed to see twice as many sources on a second bank of shifted inputs. Due to space constraints, some manufacturers have created ‘Shift’ buttons to allow for more physical inputs to be on the switcher chassis than there are physical buttons. So if you have two rows of buttons with eight buttons each, then you probably have an eight input switcher. The number of buttons on the crosspoint traditionally is the number of inputs you have on the switcher. The Crosspoint is usually laid out with one row on top of the other – one row being Program (live on the air) and the other being Preview (what you are previewing to go to air next). CrosspointĪ crosspoint on a M/E refers to the two rows of buttons that have your video inputs on them. If you have a punch switch that mechanically selects between sources, and your image on the screen loses sync for a second, that is not a Mix Effect! That would be referred to as a punch switch, bang box, contact closure, pushbutton, bud box, SPST, dead man switch, panic button, etc.Ī Mix Effect is used on professional switchers and consists of the following: a crosspoint, a transition area with cuts and a true mix or wipe, a T-Bar, keyer, and special outputs. So before we get to the M/E, we should talk about what a M/E isn’t. All the functions that the switcher performs define what that Mix Effect does. One big question that commonly arises is: What does M/E mean? What does it do for me? Why do I care? What does M/E mean?Ī M/E (sometimes referred to as a ME or MLE depending on manufacturer) is a Mix Effect. Maybe you’re looking through all the features and you don’t really know what all the letters and numbers mean. ![]()
