Using DaVE

DaVE is a Program/Preset mixer: this means, whatever is on the Program bus is ALWAYS what's going out. The Preset bus is what will go out if you fade across to it using the T-Bar. If you put one thing (call it 'A') on the program bus, and 'B' on the preset bus, and fade between them, at the end of the fade, DaVE will swap them over to make them the right way round again ('B' on the program, and 'A' on the preset). So, watch out! the T-Bar does not indicate which bus is live!

You can switch between items instantly, by just pressing a different source on the Program bus. DaVE can also do the transitions for you, use the 'take' button.

DaVE's panel allows you to change the transition type, (wipes, dissolves, pixelation, PiP...), the colour of the transition, it's size, position, angle, axis... DaVE also has a Huge pile of effects it can apply to the output - the list is almost endless, and again, you can change almost every aspect of them. Warning Attempting to master all of DaVE's quirks and abilities is impossible, don't try it! Also, most of the effects are incredibly cheesey.



Control cable

Preliminary tests have revealed that DaVE's GPI port does indeed power different pins of the DB-9 connector when different sources are on the program Bus, (or preview bus aswell during an M/E operation).

Do not draw more than around 10ma from this (5v N.L.V) , or dave might get angry.
