One box, one power supply, and up to 16 devices extended easily from a rack without the mess or headache of multiple extenders. That is the purpose of SmartAVI''s new Rack Series of A/V component management solutions. Rather than buy multiple extenders for your rack components, and having to find power strips or numerous power outlets for the adapters, our Rack Series of extenders allows for up to 16 inputs and 16 outputs (30 feet each way) and one power supply. Say goodbye to a tangled mess of wires and extension cords and hello to a dynamic, smart component management solution.Rack-XTPro is a high-resolution UXGA and audio extender system (transmitter and receiver) designed to broadcast desktop video, stereo audio, RS-232 and infrared signals over unshielded, twisted pair cabling.
