D
Software package: The standard software includes many device drivers ac-
cording to the current state of development.
D
1–4 Mix / Effect Stages
D
Keyers and wipe generators see below (Key Functions, Wipe Generators).
D
32 DSC/SDI inputs each with modifier (Input Correction) for lum., contrast, hue,
color balance.
D
1 x sync input (analog blackburst)
D

port for extern Tally/GPI needed !)
D
5 x RS232C serial interface
D

Limitation using small mainframe
D
In conjunction with the small mainframe, the switcher–internal sources COL
BGD 2 and COL BGD 3 are not available.
D
There is only one wipe generator board which, as in the DD35–4, is used by
both M/Es (WiperFlex). It can be determined by the configuration how to assign
the two generators on the board to the M/Es.
D
A further restriction concerns the connections to the future FX processor (mon-
tage processor slot). Two of the input and output connections each lead to the
second input processor. It follows from this that with a minimum configuration
(only one input processor with 16 inputs) only two inputs and two outputs of the
FX processor can be used.
