A psi broadcaster is a piece of protoss technology used aboard the Daelaam Ark. It used a khaydarin crystal to power the shields that prevented access to specific areas of the ship, including the warp drive. When Niadra infiltrated the ship, she destroyed these broadcasters in order to disable the ship's shields and proceed unimpeded.
