V-TONE ACOUSTIC DRIVER DI ADI21

Acoustic Amp Modeler/Direct Recording Preamp/DI Box

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

(1)

The

TREBLE

control governs the high-frequency range of the signal (

±

12 dB).

(2)

The

BASS

control allows you to boost/cut the low-frequency range (

±

12 dB).

(3)

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.

(4)

The

LEVEL

control adjusts the output level of the ADI21.

(5)

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.

(6)

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.

(7)

The

-20 dB PAD

switch attenuates the output level of the BAL OUT (see

(10)

)

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.

This LED illuminates when the effect is activated (see

(8)

).

Connectors

(10)

Use this ¼" TS

INPUT

connector to plug in the instrument cable of your

acoustic guitar or other instruments.

(11)

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.

(12)

The unbalanced ¼" TS

OUT

connector sends the signal to your guitar amp.

SERIAL NUMBER

. The serial number of the ADI21 is located at the bottom.

(14)

BATTERY COMPARTMENT

. Open the lid to install or replace the 9 V battery.

◊

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.

(15)

Power supply connector

(15)

Use the

DC IN

connection to plug in a 9 V power supply (not included).
