Behringer ADI21 overview

  • 1Description

The Behringer V-Tone Acoustic ADI21 is a versatile stomp box designed to enhance performance with acoustic guitar in both live and studio settings. With an effective Three Band EQ, Tube/Microphone Emulation, and a Ground Lift Switch to combat unwanted hum, the ADI21 offers greater control over the range of acoustic possibilities, without compromising the integrity of the sound.

Tube/Microphone Emulation
Authentic tube/microphone modeling circuitry provides the equivalent natural warmth and presence as an acoustic guitar miked through a tube pre-amp.
Three Band EQ With Mid Frequency Sweep
The ADI21's EQ controls allow for greater flexibility of tone, as well as providing a defense against feedback and a means of eliminating the harsh harmonics of certain pickups.
Direct Injection Output
A dual Direct Injection (DI) mode is controlled by a durable footswitch, enabling the player to alternate between tube/microphone emulation and standard DI in bypass mode.
Super-High Impedance
The input and outputs are wired to retain maximum signal integrity and dynamics.
Ground Lift Switch
This switch helps to combat typical ground loop problems, such as 50/60 kHz hum.
Other Uses
The ADI21, while designed with acoustic guitar in mind, is a versatile component that can be used with other instruments to create new sounds. It can also be connected directly to the microphone input or auxiliary send/return of a mixing console for live or studio applications respectively.

    Behringer ADI21 reviews

    V-TONE ACOUSTIC ADI21 is rated 4.4 out of 5 by 15.
    Rated 5 out of 5 by from Great Bang for Your Buck I own a Yamaha CPX900 with 4 piezo pickups, and wanted to improve my lead sounds. After reading about the ADI21, I decided to give it a try. When I received the unit, I plugged it in and carefully listened to the sound. The controls are laid out in a sensible way, EQ adjustments are easy to hear, sweepable mids are a nice touch. The mic modeling blend control is where the pedal comes alive. As you reach 50 per cent blend between the pickups and the modeled sound, my guitar took on a new tone and presence....hard to describe, just a better sound, more pleasing to the ear, with more clarity and warmth. For the money, a big sonic improvement to my sound.

    Rated 4 out of 5 by from Great Sound On A Budget I couldn't believe the difference the ADI21 made in the sound of my guitar. I play an Epiphone DR 500MCE with the Shadow eSonic pickup system, which sounds great to begin with, but can be a little harsh on the high end. The ADI21 allows me to custom tailor the sound without losing the ringing chime this guitar produces. With the extensive tone shaping capabilities and the blend knob, you can dial in a multitude of tones. I use it plugged directly into a recording console, and it's absolutely quiet. If you're looking for an inexpensive device to breath new life into you sound,the ADI21 might fit the bill.

    Rated 4 out of 5 by from What a great product I use this ADI21 to plug my acoustic directly in to my church mixer. Before this box I had very little umph!..Now with this stompbox with DI out I have warmth and more control over my sound. The Blend TUBE SIMULATION is a definite must have. The cost is too good to be true. Now you can have the sound your acoustic guitar was meant to have. This is NOT a 'You get what you pay for' product. I'd have to say you get WAY more than what you pay for. I rated it as a 4 star only because the knobs are a little hard to see what actual setting you have while standing up.

    Rated 3 out of 5 by from Ok, I guess - might give it another go It's a little difficult rating this. I suppose that it might do what it's supposed to, but it's hard to say. Product seemed sturdy enough, considering an all-plastic construction. I was able to tweak sound a fair amount using the 3 knob equalizer. I just couldn't get rid of hum, and consequently, it didn't serve very well as a DI box. I suppose it could have been a bad pickup. Either way, I ultimately had to return the product. I wouldn't rule it out in the future, but I also couldn't rave about it. Willing to accept that some of my experience could be colored by user error/inexperience.

    Rated 4 out of 5 by from V-TONE ACOUSTIC ADI21 Behringer Entry level direct box with the Acoustic /Electric Guitarist in mind with a surprising amount of features for the price. It's an analog modeling acoustic guitar preamp/stompbox with tube/microphone modeling circuitry - as if your acoustic guitar was miked through a tube pre-amp. 3 band EQ and 1/4 inch/XLR inputs. Going to be used in a church going directly through the PA. I have no idea how they sell quality that cheap.

    Rated 5 out of 5 by from Great Value!!! Use this in Worship team. It is a DI box and it takes some of the pizeo brightiness away. Everyone thought it was an improvement. It is just a lot bigger than my little stick It has a button so you can bypass if you have some lead to play and the go back to the mellow strumming. DI that I used from Radio Shack. But its not any larger than most DI boxs. I would highly recommend.

    Rated 4 out of 5 by from Good DI I purchased This product for use in home studio work. NO it does'nt compare to a 180 dollar L.R.Baggs but if you have the ability to tweak. It gets the job done. With the Money I saved I can Buy More equipment.Keep Your adjustments around 3-4 then tweak from there.

    Rated 4 out of 5 by from Performed As Expected I use it as a direct in box. I was hoping for something similar to the Fishman Aura without the tweaking. Since I didn't really expect this, I can't say I'm truly disappointed that the acoustic simulation isn't great. It's a nice, solid direct in box, though.
