The Behringer BDI21 is an amazing device that combines an active DI box with our unique tube emulation circuitry. It's like having a whole collection of vintage tube amps right at your feet! Use the Blend control to mix the tube emulation with your direct bass signal. If you prefer the pure, straight tone of your instrument, just step on the switch and it works as a top - notch active DI box. Key features include an analog modeling bass preamp with DI recording output. It competes with leading market products. The authentic V - TONE modeling technology can create various tones from big vintage tube sounds to funky slap and crunchy distortions. It packs a ton of great amp tones in one stomp box. You can mix the tube emulation with the direct bass signal. There's a Presence control for better definition and upper harmonics, along with a 2 - band EQ tuned for bass guitars. It has a dual DI mode, and the output is available on ¼'' TS or balanced, gold - plated XLR connectors. The ground lift switch solves ground loop problems. It runs on a 9V battery or an optional Behringer PSU - SB DC power supply (not included). It's designed and engineered in Germany.


Using the Behringer BDI21 is easy. First, connect your bass guitar to the pedal. You can choose to use a 9V battery or connect it to the Behringer PSU - SB DC power supply (you'll need to get the power supply separately). Once it's powered on, use the Blend control to adjust how much of the tube emulation you want in your sound. If you just want the pure sound of your bass, step on the switch to use it as a regular active DI box. The Presence control helps you add more definition and upper harmonics to your tone, and the 2 - band EQ is tuned for bass guitars, so you can get the perfect sound. When recording, you can use the dual DI mode. You can choose the output on either the ¼'' TS or the balanced, gold - plated XLR connectors. Be careful when handling the pedal to avoid dropping it. If you're using a battery, remember to replace it when it runs out. To keep it in good condition, store it in a dry place and clean it gently with a soft cloth from time to time.
