Magic DaVE

Systems

Magic DaVE

• Mark 1 Mainframe, Option card slot non-functional (fault on PCB, doesn't affect performance for us)
• Compact Control panel (no direct access to keyers & Key bus) Software Version 3.0.

"F" Magic Dave

• Mark 2 mainframe, Fully functional
• Compact panel with last software provided by Snell & Wilcox.

Connection

• 4 inputs, all analogue, each with the following options per input:
  • Composite on BNC
  • YPbPr on 3xBNC
  • Y/C on Svid

• Key video input
  • Composite on BNC
  • For inputting a Matte / cut area

• Preview output
  • YPbPr / RGB on shared BNC's (3xBNC total)
  • Settable via service menu

• Program outputs
  • YPbPr on BNC (1 of) (3xBNC per set)
  • Composite on BNC (2 of)
  • Y/C on Svid (2 of)

• Snell & Wilcox Rollcall

• Ref in & loop
  • For locking DaVE's output onto an unsyncronised source, or another mixer

• Black Burst (4 of)
  • For sending a signal for other devices to lock onto

• GPI port
  • input & output configurable
  • default setting:
    • Active Low tally - a null output signals the source is in use in either the DVE (for effects/mixing) or on the program buss.

• RS232
  • DaVE can be controlled by a PC

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.
