Video DC Block Instruction Card  
The Video DC Block isolates the DC offset from a video source to an Extron product, prevent-  
ing video distortion. Twist Video DC Blocks onto the RGB inputs of Extron products, then  
twist cable onto the Video DC Blocks. Horizontal (H) and Vertical (V) channels do not require  
them. The small shape of the adapter ensures the back panel of an Extron Matrix looks neat  
even when many Video DC Blocks are attached.
