VIRTUBE VT30FX/VT15FX/VT15CD User Manual
(11) 
The TREBLE control adjusts the treble frequencies. 
◊ 
On the VT30FX, the controls  ( 9 ),  (10)   and  (11)  are effective on the 
OVERDRIVE channel only, since this amplifi er has a dedicated equalizer 
for the CLEAN channel (see also  ( 4 )   and   ( 5 )). 
(12) 
The VOLUME control adjusts the volume level of the OVERDRIVE channel.
2.1.3  FX section (VT30FX and VT15FX only)

2.1.4  Connectors and POWER switch
(16) 
The VTC push button activates and deactivates the VTC Virtual Tube Circuitry.
(17) 
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 built-in loudspeaker of the VIRTUBE.
(18) 
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 built-in loudspeaker of the VIRTUBE 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 ¼" TS connectors. If hum problems occur, you could insert a 
DI box, e.g. BEHRINGER ULTRA-DI DI100 or DI120.
◊ 
With too high a volume level some headphones tend to produce 
distortion. Please turn down the volume a bit, until distortion stops.
(19) 
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 FX on and off (VT30FX only).
(20) 
The POWER switch turns your VIRTUBE on and off. It should always be 
in the OFF position when connecting the unit to the mains. 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.

The VIRTUBE is connected to the mains using a standard IEC receptacle. 
A suitable power cord is included with the unit.
(22) 
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 and120 V. Please note: when operating the unit outside Europe at 
120 V, a higher fuse rating is required (see Chapter 4, “Installation”).
