The PDB4 is a 4-channel passive direct box featuring four high-quality direct boxes with fully isolated transformers, housed in a 1U 19-inch rack unit.
The inputs and outputs of each of the four channels are isolated to maximize channel separation. Transformer isolation on each output helps eliminate electrical interference and ground loops.
It is a stable and reliable interface for connecting the outputs of electronic musical instruments (or other audio sources) to the balanced inputs of audio consoles and other balanced-signal equipment. The PDB4 also allows a music source to be connected to an instrument preamplifier while simultaneously feeding a mixer.
