About DBX dB12

The dbx BD12 is a high performance, active direct box housed in an industrial strength enclosure and includes custom dbx mu-metal-shielded audio transformers, high-quality Neutrik connectors and low-noise circuitry. The box includes a pad switch to accommodate instrument, line and even speaker level signals. A polarity invert switch can alter the phase relationship between the direct and mic'd sound, while a ground lift switch helps to tame any ground hum or buzz.

While providing a clean signal free from interference, the solid, stable footprint of the enclosure prevents the box from being dragged around the stage and the unique contoured underside allows secure stacking of multiple units.
