The Behringer ADI21 Acoustic Amp Modeler Direct Recording Preamp DI Box combines the features of an active DI (direct injection) box with Behringer’s proprietary microphone/tube emulation.
But you don’t have to use the emulation feature. The ADI21 also functions as a superb active DI box. The Blend control allows you to mix the amount of modeled tone with your instrument’s normal output. The resulting sound is more natural with smooth saturation, just as if your guitar were being miked. Armed with an onboard 3-band EQ, with sweepable mids to keep feedback under control, the ADI21 effectively eliminates the harsh harmonics of piezo pickups. The output is laid out on ¼ inch TS or balanced gold-plated XLR connectors, which can be used to send a low-impedance signal to the mixing console or straight to tape. Included is a ground lift switch to eliminate annoying ground loop hum problems. You can power this little lifesaver with a 9 V battery or a PSU-SB DC power supply (not included).
