7.2 Linear key - Quick DSK 2 Setup
Note: The DSK 1 and DSK 2 keyers can only be used for Linear or Luma keying . Chroma keying is not
supported on DSK 1 and DSK 2.
In this downstream keying example, we are supplying the SE-1200 MU with a live video signal on input 2,
this is selected on the Program and Preview rows. We have also connected a CG-350 Character Generator
(separate purchase) which is supplying separate KEY and FILL signals to inputs 3 and 4. These two CG-350
inputs will be used for Linear keying the CG- text and graphics over the live video from input 2.
Step 1: Choose the DSK Keyer channel that you wish to use. In our example, we clicked the DSK 2 button on
the AUX BUSES panel .

Step 2: We then choose the Lin or Linear and Split buttons from the KEYER CONTROLS panel to select a
linear key.
Note: If the DSK input only has one source ( FILL ) for keying, press Self key button. In our example the DSK
input has two sources for Fill and Key , so we select the Split button instead.
