The PDB4 is a 4-channel passive direct box that features four quality direct boxes with fully isolated transformers. In a 1U 19-inch rack, the inputs and outputs of each of the four channels are isolated to maximize channel separation. Transformer isolation on each output helps eliminate electronic interference. It is a solid and reliable interface for connecting outputs of electronic musical instruments to the balanced inputs of an audio console and other products with a balanced signal.
The PDB4 also allows connecting a music source to a musical instrument preamp while simultaneously connecting it to a mixer.
