Here's what Behringer say about the BDI21 Bass Preamp:

The BDI21 combines the features of an active DI (direct injection) box with our proprietary tube emulation circuitry. It’s like having a truckload of vintage tube amps right at your toes! The Blend control allows you to mix the amount of tube emulation you want with your direct bass signal. And if you just want your instruments straight, pure tone – just step on the switch and the ADI21 functions as a superb active DI box.

You’ve Got Control

With its dedicated Drive, Treble, Bass, Level, and Presence dials, the BDI21 goes above and beyond the call of duty, giving you vintage tube tones for funked-up slap, gonzo overdrive and everything in-between. You can use the BDI21 as a recording output DI with tube emulation, or as a standard active DI box, when running in bypass mode. The output is presented in ¼ " TS or balanced, gold-plated XLR connectors. There's also a ground lift switch that eliminates typical ground loop hum problems. You can power this bad boy with a 9V battery or our PSU-SB DC power supply (not included).
