The Art PDB4, is a 4-Channel Passive Direct Box passive direct box that features four quality fully transformer isolated direct boxes in a 1U 19-inch rack mount chassis. Inputs and outputs of each of the four channels are isolated to maximize channel separation. Transformer isolation on each output helps to eliminate system ground loops.
