* For customers of the EU, different designations can be applied.
Customers from the EU get further informations from BEHRINGER
Support Germany.
1.1 Before you get started
Your product was carefully packed at the factory to ensure safe
transport. Nevertheless, if the box is damaged inspect the unit
immediately for signs of damage.
+
+
The tone quality may diminish within the range of pow-
erful radio broadcasting stations and high-frequency
sources. Increase the distance between the transmitter
and the unit, and use shielded cables for all connec-
tions.
+
If the unit is damaged please do NOT return it to us,
but notify your dealer and the shipping company im-
mediately; otherwise, claims for damage or replacement
may not be granted.
We would like to draw your attention to the fact that
extremely loud sound levels may damage your hearing
as well as your headphones. Turn the MASTER LEVEL
control fully to the left before you switch on the unit.
Make sure you select a suitable volume at all times.
+
+
+
Otherwise, always use the original box to prevent dam-
age during storage or transport.
Make sure that children cannot play unsupervised with
the unit or its packaging.
Please ensure proper disposal of all packing materials.
Recylce whenever possible.
Ensure adequate air supply and to avoid overheating do not place
the unit near radiators etc.
+
Please make sure that all devices are properly grounded/
earthed. For your own safety, never remove or disable
the ground/earth conductors from the devices or on the
power cords. The unit must always be connected to the
mains outlet with a protective grounding connection.

nel is active.
[24] The CD IN connector allows you to connect the output signal
of a CD player, tape deck, or CD/MD walkman. For example,
you can play back music CDs or CDs accompanying a guitar
tutor while practising. This connector can also be used as
a LINE OUT output. In this case, the guitar signal is output
with no speaker simulation applied and can be routed to
an external amp or mixing console. This will not mute the
VIRTUBE’s built-in loudspeaker.
[10] The GAIN control determines the amount of gain applied
and hence the degree of distortion in the OVERDRIVE
channel.
[11] The OD1/OD2 button (VT100FXH and VT100FX only)
switches between two different overdrive sounds.

The headphones output signal can also be routed to a
mixing console or other sound reinforcement system. To
do so, connect the headphones output with the line input

Some headphones tend to produce distortion with too
high a volume level . Please turn down the volume a bit,
until distortion stops.

Please note: Merely switching the unit off does not
mean that it is fully disconnected from the mains. To
disconnect the unit from the mains, pull out the mains
connector. Before installation, please make sure that
the mains connector has not been damaged. If you do
not use the unit for an extended period of time, please
disconnect it at the mains.
3. APPLICATION EXAMPLES
The VIRTUBE features plenty of connectors for a wealth of ap-
plications. Here’s a few examples of how flexible your VIRTUBE
can be:
3.1 Set-up for practicing with playbacks
2.2 Rear panel
[27] The VIRTUBE is connected to the mains using a standard
IEC receptacle. A suitable power cord is included with the
unit.
[28] FUSE HOLDER/VOLTAGE SELECTOR. Before connecting
the unit to the mains, ensure that the voltage setting matches
your local voltage. Blown fuses must be replaced with a fuse
of the same type and rating. On some units, the fuse holder
can be switched to one of two positions, i.e. 230 V and
120 V. Please note: when operating the unit outside Europe
at 120 V, a higher fuse rating is required (see Chapter 4,
“Installation”).
[29] This is where the fan of the unit is located.
[30] The SPEAKER OUT connectors (only one on the VT100FX
and VT50FX) can be used to connect external speakers with
a miminum impedance of 4 Ω. The outputs of the VT250FX
deliver 50 Watts of power per channel (L/R). Always use
speakers with a minimum impedance of 8 Ω to ensure maxi-
mum power output. Using the SPEAKER OUT connectors
will mute the built-in loudspeakers.
2.2.1 FX LOOP
[31] The FX LEVEL button allows you to adapt the FX LOOP to
the operating level of an external effects device (+4 dBu/-
10 dBV).
[32] The VIRTUBE provides a serial insert path for inserting
external effects (e.g. reverb processor). To do so, connect
the FX SEND jack to the input of the effects device.
+
The FX SEND can also be used as a parallel output with
no effects, for example, to record a “dry” guitar signal.
As long as the RETURN jack is not in use, there will be
no break in the internal signal path.
[33] Connect the FX RETURN jack to the output of the external
effects device. The VT250FX has two jacks (L/R) because
it is a stereo amplifier.
Fig. 3.1: VT50FX standard set-up
[34] Use the FOOTSWITCH jack to connect the 1/4" TRS plug of
the footswitch supplied with the unit. The footswitch performs
a dual function: it switches between the two channels and
turns the DIGITAL FX on and off.
For practising in the rehearsal room or at home, please wire your
VIRTUBE as shown in fig. 3.1. Connect a CD player or drum com-
puter to the CD IN input. If you want to practice with headphones,
connect your headphones to the PHONES jack. The built-in loud-
speaker will be muted automatically. Connect the dual footswitch
supplied with the unit to the FOOTSWITCH jack on the VIRTUBE.
The CHANNEL footswitch switches between the channels. The
EFFECT button switches the effect on and off.

GI100
Fig. 3.2: Recording set-up with the VT100FX
If you want to use your VIRTUBE in a home-recording or studio
environment, please wire it as shown in fig. 3.2. Of course, you
can still use a CD player or drum computer in this set-up. This
is not shown here to provide for a better overview. Connect the
input of the effects device to the FX SEND and the effects output
to the FX RETURN.
If you want to record your guitar signal with effects, connect the
PHONES output to your mixing console, audio sequencer or
multi-track recorder.
To record a “dry” guitar signal with no effect, it is best to use the
FX SEND connector. You can use both outputs at the same time,
for example, to record signals via the FX SEND output (no effect),
while monitoring them via the PHONES output (with effect).
Fig. 3.3: Set-up comprising VT250FX and one speaker box
Fig. 3.3 shows how the LINE OUT signal is routed to a mixing
console. You can connect external guitar speaker boxes to the
SPEAKER OUT outputs of the VIRTUBE (VT100FX and VT50FX
have only one output) to achieve more power and higher volume
levels on stage. When the VT250FX is used, we recommend con-
necting two separate speaker cabinets for stereo applications or
one stereo cabinet (e.g. BEHRINGER ULTRASTACK BG412H).
Instead of an external 19” effects processor, you can also use a
wah-wah pedal or other stomp box. However, please note that the
FX LOOP is post-preamp, i.e. after the distortion stages.

VIRTUBE VT100FXH/VT100FX/VT250FX/VT50FX
3.4 Wiring the VT100FXH
The VT100FXH has two SPEAKER OUT outputs for connection
of one or two external speaker cabinets. To achieve maximum
power output on the VT100FXH, both speaker outputs should
be connected to speaker cabinets with a minimum impedance of
4 Ω. Connecting headphones to the PHONES jack will automati-
cally mute the speaker outputs.

Fig. 4.3: Stereo adapter cable
4. Installation
Except for the headphones output and the CD IN input (1/4" TRS
connectors), all audio inputs and outputs on the BEHRINGER
VIRTUBE are on 1/4" TS connectors. Please see Chapter 5,
“Specifications” for more information.
+
Please ensure that the unit is installed and operated
only by people qualified to do so. During installation
and operation the user must have sufficient electrical
contact to earth. Electrostatic discharge may affect the
operation of the unit.
