OVERVIEW
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.
