The A-H484 is an A-BUS 4-zone 8-room 4-source Audio Distribution Hub. Using the IR-repeating in the A-KP2 Amplified Keypad Module and the A-LRC-1 hand held A-BUS remote the A-H484 allows each of 4 zones to independently select any of 4 audio sources connected. Each of the 4 zones can support 2 Amplified Keypad Modules making it possible to create an 4- zone 8-room system.
