The ART PDB4 Four-Channel Passive Direct Box is a deceptively simple, yet surprisingly useful addition to any serious collection of audio equipment. The PDB4 is a four channel 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.

It is a rock solid, roadworthy interface for connecting outputs of electronic musical instruments (or other audio sources) to the balanced inputs of mixer consoles and other balanced audio products. The PDB4 also allows connection of a music source to an instrument amplifier while simultaneously patching it to a mixer.

Electric guitar and bass pick-up output signals, keyboards and line level signals, DJ console output signals, speaker level signals. However you decide to use it, we're sure you'll find the ART PDB4 Four Channel Passive Direct Box to be an indispensable addition to your audio equipment arsenal.
