PDB4
4-Channel Passive Rackmount DI
The PDB4 is a four-channel passive DI in a 1U rackmount format. It is ideal for connecting multiple unbalanced instrument, line, or speaker signals to balanced inputs.
Each input signal is sent to a balanced, transformer-isolated XLR output and a parallel Thru jack, so it can simultaneously be connected to an amplifier on stage.
All channels feature a switchable ground lift to help eliminate hum, and switchable attenuation with up to 40 dB of gain reduction to handle high signal levels.
As a fully passive design, the PDB4 doesn’t require an external power source. Passive DIs are often a great match for powered sources such as synthesizers or guitars and basses with active preamps.
