4-Channel Passive Direct Box

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.

Product Description

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.
