BEHRINGER V-TONE ACOUSTIC ADI21
WELCOME TO BEHRINGER
Thank you for showing your confidence in us by purchasing
the V-TONE ACOUSTIC ADI21. This high-quality acoustic guitar
driver is designed for all acoustic guitar players who are looking
for more sounds to reach maximum flexibility and creativity.
Thanks to its high-performance EQ section (including parametric
mids) and the integrated Tube/Microphone Emulation, the ADI21
gives your guitar natural sound with smooth saturation, just as if
it were being miked. In addition, the ADI21 functions as a standard
ultra-transparent direct injection box when used in bypass mode.
A DI (Direct Injection) box allows you to send a signal directly
from an unbalanced, high-impedance output (like an electric guitar)
and connect it directly to the balanced mic input of a mixing
console.
Whether for stage, recording, rehearsal or warm-up,
BEHRINGER’s V-TONE ACOUSTIC ADI21 is a natural choice for
those who are seeking great tone with a simple set-up.
CONTROL ELEMENTS
Control elements
The TREBLE control governs the high-frequency range of
the signal (+/-12 dB).
The BASS control allows you to boost/cut the low-
frequency range (+/-12 dB).
Use the MID control to boost or cut the mid-range
frequencies (+/-12 dB). The MID FREQ control lets you
select the middle frequency (170 Hz to 3.5 kHz) that will be
boost/cut.
The LEVEL control adjusts the output level of the ADI21.
The BLEND control activates the integrated tube/
microphone emulation circuitry. In most cases, you will
probably set it to maximum (100%). If you want to hear
some of the distinct timbre of a piezo pickup or reduce the
amount of compression, simply turn the control
counterclockwise.
When activated, the GND LIFT disconnects the ground
connection between input and output. Depending on the
grounding of the connected equipment, this can eliminate
hum or ground loops.
The -20 dB PAD switch attenuates the output level of the
BAL OUT (see ) by -20 dB. It should be activated
when the output level is too high for the microphone input
of the mixer channel.
+
Before using the PAD switch, be sure that it is the
mic preamp on the mixing console that is clipping
and not the ADI21. You should only attenuate the
output signal via the PAD switch if the CLIP LED of
the mic channel lights up frequently or remains
lit.
Use the footswitch to activate/deactivate all the tone
functions (EQ, microphone/tube emulation). When
deactivated, the ADI21 functions solely as a standard
transparent DI box.

Connectors
Use this 1/4" TS INPUT connector to plug in the instrument
cable of your acoustic guitar or other instruments.
BAL OUT is the ADI21’s balanced mic level output. Use a
high-quality, balanced XLR (microphone) cable to connect
the driver to a mixing console.
The unbalanced 1/4" TS OUT connector sends the signal
to your guitar amp.

BATTERY COMPARTMENT. Open the lid to install or

REQUIREMENTS”).
+
The ADI21 is powered as soon you insert a plug
into the INPUT. The battery is “disconnected” when
the plug is removed. For this reason, the ADI21 has
no on/off switch. To prolong battery life, always
disconnect the input when the driver is not in use.
