Product Description

The Behringer ADI21 V-Tone Acoustic Driver is a professional acoustic amp modeler and active direct injection (DI) box designed to enhance the sound of acoustic-electric guitars. Utilizing Behringer's proprietary V-Tone modeling technology, the ADI21 recreates the warmth and depth of high-quality microphone and tube amplifier setups without requiring expensive studio equipment.

Its intuitive control layout includes dedicated Treble, Bass, Mid, Mid Frequency, Level, and Blend controls, enabling musicians to fine-tune their acoustic tone for any venue or recording environment. The blend control allows seamless mixing between the direct pickup signal and the modeled acoustic tone, providing maximum tonal flexibility.

In addition to tone shaping, the ADI21 functions as a high-quality active DI box, allowing direct connection to mixers, audio interfaces, PA systems, and recording consoles while maintaining signal integrity and minimizing unwanted noise.

Built with rugged construction and portable design, the ADI21 is an ideal solution for live performance, church worship setups, acoustic gigs, studio recording sessions, and professional audio applications.
