I also have projector hooked to it. The PC has a blu-ray drive. The projector projects to the screen behind me. So I face front when using my pc and face back when watching a movie on the projector. Therefore, I need to switch speakers front to back and left to right, i.e. diagonally. To that end I am building a box with 4 SPDT switches in it.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/smegnl.medina.oh.us\/wp-content\/uploads\/2026\/03\/4switch.jpg.webp\" alt=\"\" class=\"wp-image-3156\" srcset=\"https:\/\/smegnl.medina.oh.us\/wp-content\/uploads\/2026\/03\/4switch.jpg.webp 800w, https:\/\/smegnl.medina.oh.us\/wp-content\/uploads\/2026\/03\/4switch.jpg-100x75.webp 100w, https:\/\/smegnl.medina.oh.us\/wp-content\/uploads\/2026\/03\/4switch.jpg-768x576.webp 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Click her to see a schematic I threw together in paint.
