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.
