VIRTUBE VT100FXH/VT100FX/VT250FX/VT50FX
APPLICATION EXAMPLES6
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.
Rear panel2.2
The VIRTUBE is connected to the mains using a standard [27]
IEC receptacle. A suitable power cord is included with the
unit.
FUSE HOLDER/VOLTAGE SELECTOR[28] . 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”).
This is where the fan of the unit is located.[29]
The [30] 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.
FX LOOP2.2.1
The [31] FX LEVEL button allows you to adapt the FX LOOP to
the operating level of an external effects device (+4 dBu/-
10 dBV).
The VIRTUBE provides a serial insert path for inserting [32]
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.
Connect the [33] FX RETURN jack to the output of the external
effects device. The VT250FX has two jacks (L/R) because
it is a stereo amplier.
Use the [34] 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 g. 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.
