This rack setup was done for a customer refinishing their basement. The idea was to have wall and ceiling mount speakers for full surround sound with everything coming back to the workroom leaving the theater area looking clean. Added in was a switch to provide wired networking to most of the basement rooms and HDMI extenders out to the cabinet mounted TV. All the products in the rack were chosen and purchased by the homeowner and installed by us. we added in the 2 switch panels to be able to easily reboot any of the equipment individually in case of future issue.
