PDB
Passive Direct Box
The PDB is a passive direct box for connecting unbalanced instrument, line, or speaker signals to balanced inputs.
The input signal is sent to a transformer-isolated XLR output and a parallel Thru jack, so it can simultaneously be connected to an amplifier on stage.
A switchable ground lift helps to eliminate hum, and switchable attenuation offers up to 40 dB of gain reduction.
As a fully passive design, the PDB 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.
Packed into a stage-proof steel enclosure, the PDB provides a high-fidelity connection to a mixer, PA system, or audio interface.

Features
- 1/4" TRS Input and Thru Connectors
- Balanced XLR Output
- Switchable Attenuation (-20 dB, -40 dB) and Ground Lift
- Passive Design - No Power Required
- Rugged Steel Case
