2. Control Elements
Fig. 2.1: VIRTUBE control elements (front panel)
2.1 Front panel
(1) The INPUT socket is the ¼" connector for your guitar. Please use a standard
¼" TS connector.
2.1.1 CLEAN CHANNEL
(2) The CLEAN CHANNEL LED lights up when the CLEAN channel is active.
(3) The GAIN control determines the volume of the CLEAN channel.
(4) The CRUNCH button (VT100FXH and VT100FX only) allows you to add some
slight distortion to your clean sound, giving it a bit of “dirt” or “crunch”.
(5) The BASS control in the EQ section allows you to raise or lower the bass
frequencies on the CLEAN channel.
(6) With the MIDDLE control you can raise or lower the midrange frequencies
onthe CLEAN channel.
(7) The TREBLE control adjusts the treble frequencies on the CLEAN channel.
(8) Press the CHANNEL button to switch between the CLEAN and OVERDRIVE
channels. The channel LED lights up when the channel is activated. With all
models you can also switch between channels using the footswitch provided.
2.1.2 OVERDRIVE CHANNEL
(9) The OVERDRIVE CHANNEL LED lights up when the channel is active.
(10) The GAIN control determines the amount of gain applied and hence the
degree ofdistortion in the OVERDRIVE channel.
(11) The OD1/OD2 button (VT100FXH and VT100FX only) switches between
twodierent overdrive sounds.
(12) The BASS control in the EQ sec tion allows you to raise or lower the bass
frequencies on the OVERDRIVE channel.
5VIRTUBE VT250FX/VT100FX/VT50FX/V T100FXH User Manual
(13) With the MIDDLE control (VT100FXH and VT100FX only) you can raise or
lower the midrange frequencies on the OVERDRIVE channel.
(14) The TREBLE cont rol adjusts the treble frequen cies on the OVERDRIVE channel.
(15) Use the CONTOUR control for additional, highly characteristic adjustment
of the midrange, allowing you to easily create traditional as well
as ultra-modern guitar sounds.
(16) The VOLUME control adjusts the volume level of the OVERDRIVE channel.
2.1.3 DIGITAL FX
(17) The DIGITAL FX LED lights up when the eec ts processor is active.
(18) Use the FX PRESET control to select one of 16 eects.
PresetFX
1 - 4Chorus/Delay
5 - 8Delay

13 - 16Flanger
Tab. 2.1: Eect s
(19) The FX LEVEL control adjusts the mix ratio between the original and
the eect signal.
(20) The REVERB LEVEL control determines the eect intensity of the
additional reverb eect.
2.1.4 MASTER section
(22) The MASTER VOLUME control adjusts both the overall volume and
the line out/headphones volume.
(23) The V TC push button activates and deactivates the VTC Virtual Tube Circuitry.
(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.
(25) The LINE OUT/PHONES jack is for headphones connection. Internal speaker
simulation is applied to the headphones signal in order to produce an
authentic signal. The VIRTUBE’s built-in loudspeaker is muted when this
connector is used.
◊ 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 on the mixing console. Use a standard cable
with 1/4" TS connectors. If hum problems occur, you could insert a
DI box, e.g. BEHRINGER ULTRA-DI DI100 or DI120.
◊ Some headphones tend to produce distortion with too high
volume level. Please turn down the volume a bit, until distortion stops.
(26) The POWER switch turns your VIRTUBE on and o. It should always be in the
OFF position when connecting the unit to the mains.
(21) The FX LOOP MIX control (VT100FXH and VT100FX only) determines
the eect intensity of the external eect (see Chapter 2.2.1 FX LOOP).
(28)
(27)(29)
Fig. 2.2: VIRTUBE control elements (rear panel)
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
◊ 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 connec tor has not been damaged. If you do not use the
unit for an extended period of time, please disconnect it at the mains.
(30)(35)
(33) (31) (32)(34)
(L/R). Always use speakers with a minimum impedance of 8 Ω to ensure
maximum 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 eects device (+4 dBu/-10 dBV).
(32) The VIRTUBE provides a serial insert path for inserting external eects
(e.g. reverb processor). To do so, connect the FX SEND jack to the input of the
eects 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.
6VIRTUBE VT250FX/VT100FX/VT50FX/V T100FXH User Manual
(33) Connect the FX RETURN jack to the output of the external eects device.
The VT250FX has two jacks (L/R) because it is a stereo amplier.
(34) Use the FOOTSWITCH jack to connect the ¼" 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 o.

If you want to practice with headphones, connect your headphones to the
PHONES jack. The built-in loudspeaker will be muted automatically. Connect the
dual footswitch supplied with the unit to the FOOTSWITCH jack on the VIRTUBE.

Fig. 3.2: Reco rding set-up with t he 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 drumcomputer in this set-up. This is not shown here to provide for a
better overview. Connect the input of the eects device to the FX SEND and
theeectsoutput tothe FX RETURN.
If you want to record your guitar signal with eects, connect the PHONES output
to your mixing console, audio sequencer or multi-track recorder.
To record a “dry” guitar signal with no eect, 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 eec t), while monitoring them via the PHONES
output (with eect).
Instead of an external 19" eects processor, you can also use a wah-wah pedal
orother stomp box. However, please note that the FX LOOP is post-preamp,
i.e. after the distortion stages.

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 automatically
mute the speaker outputs.

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
connecting two separate speaker cabinets for stereo applications or one stereo
cabinet (e.g. BEHRINGER ULTRASTACK BG412S).
