Behringer V-TONE GUITAR GDI21 Manual

WELCOME TO BEHRINGER
Thank you for showing your confidence in us by purchasing
the V-TONE GUITAR GDI21. This high-quality guitar modeling
driver is designed for hands-on musicians and no-frills types.
We have rebuilt different circuitries and components from famous
amps, and packed them into one housing. You can alternate
between several different amp re-creations, gain settings and
mic placements with a flick of a switch—intuitively and with
minimal effort. In addition, the GDI21 functions as 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 GUITAR GDI21 is a natural choice for all
players who want an arsenal of different tones.
WEQM LEVEL control adjusts the output level of the GDI21.
Use the AMP switch to select one of three great classic
tube amps. You will recognize these classic amp tones as
soon as you hear them. For crystal-clear, transparent
sounds with dynamic bass select TWE(E)D. For aggressive
mids and incredible sustain select BRIT(ISH). Rounder and
more evened-out (yet still sophisticated) sounds can be
dialed up if you select CALIF(ORNIAN); it’s perfect for
leads.
Use the MODE switch to dial up one of three gain settings
(HOT, HI G(AIN), CL(EA)N) that you want to combine with
the amp setting.

The MIC switch simulates the microphone placement
(orientation and distance) in relation to the cabinet. Select
CL(AS)SIC (distant mic placement without ambience) to
achieve high mid-range content and a greater definition of
notes like with classic early tube amps. In C(E)NT(E)R (close
miking at the center of a cone) you get greater high mid-
range content and increased low-end for mega crunchy
results. OFF (A)X(IS) (close miking at the edge of a cone)
is very similar to CENTER, but produces a smoother, softer
sound with less upper mid-range content; perfect in
combination with MODE position HOT.
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.
Use the footswitch to activate/deactivate all the tone
functions (EQ, DRIVE, modeling). When deactivated, the
GDI21 functions solely as a standard transparent DI box.

Use this 1/4" TS INPUT connector to plug in the instrument
cable of your guitar or other instruments.
BAL OUT is the GDI21’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.
