Many thanks to Tom Underhill for these shapes. The stencil is comprised of various terminal connectors, such as RCA Audio and RCA Video terminals, as well as various shapes for the back-plate and functional groups.
Through the VGOBN (Visio Good Ol’ Boys Network) I recently received a finely-crafted Audio-Visual Shapes Visio stencil, full of shapes that you can use to layout your home theater wiring projects.
