Behringer - a brief history


Microphone/tube emulation delivers excellent, natural sound





Sometimes piezo pickups sound artificial and overly bright. By combining the features of an active DI with proprietary microphone/tube emulation circuitry, the Behringer V-Tone ADI21 acoustic amp modeler restores warmth and low-end response to your tone, resulting in a rich, natural sound. You can also use the ADI21's blend control to mix the amount of modeled tone with your instrument's normal output, granting you enormous tonal versatility.





Onboard EQ shapes your tone and conquers feedback





By using the V-Tone ADI21's onboard 3-band EQ, you can effectively eliminate the harsh harmonics of piezo pickups. The EQ's sweepable mids grant you even more tone-sculpting power. You can also adjust the ADI21's EQ in order to reduce the inevitable feedback that occurs when you amplify an acoustic guitar onstage. Complete with a ground lift switch, the ADI21 is an onstage lifesaver!





Behringer - a brief history





Uli Behringer showed an interest in music technology design at a young age, building his own synthesizer by the age of 16. In 1982, Uli began studying sound engineering and classical piano at the Robert Schumann conservatory in Dusseldorf, Germany. Uli's defining moment came when he was repairing a signal processor made by a high-end manufacturer. Despite the processor's expensive price tag, Uli realized that its internal components could be bought for a fraction of the cost. Being a strapped-for-cash student, Uli began building his own signal processors. Before he knew it, other students began requesting equipment from him. In 1989, after being bombarded with more orders than he could handle by himself, Uli created Behringer, Inc.
