Use this 6ft Plenum Rated DC power cord to supply power to the Trulink AV Controller. Add flexibility to the installation by powering the Controller from the Trulink Audio Amplifier or an alternate power source to save an Additional AC outlet from use. Specifically designed to easily connect to the AV Controllers Multiport Controller Interface Adapter, the power cord is a 5.5mm x 2.1mm DC Barrel plug to stripped and tinned wire. This provides a secure power connection that will remain firmly in place to ensure consistent and reliable performance of the AV Controller.
