Setup
1.
Turn the POWER LEVEL knob on the amp to the minimum position.
2.
Connect the included AC adapter to the DC12V jack (DC19V jack on the
VX50 GTV), and then plug the AC adapter into an AC outlet.
Only use the specified AC adapter. Using any other AC adapter may
cause malfunctions.
3.
Plug the cable that’s connected to your guitar into the INPUT jack. If an
audio player will be used, connect it to the AUX IN jack.
4.
Hold down the power button until the LED on the top panel lights up and
the amp is turned on.
Tip
To turn off the amp, hold down the power button until the LED turns off.
5.
Slowly raise the POWER LEVEL knob to adjust the volume.
Auto power-off function
The amp has an auto power-off function. With this function, the amp is auto
-
matically turned off if there is no operation or input for approximately 1 hour.
When the amp is turned off, it is not turned back on, even if a knob or selector is
operated. After the amp is turned off, turn it on again.
The auto power-off function is activated if the input is only to the AUX IN
jack or when the input level to the INPUT jack is extremely low.
With the VX50 GTV, the auto power-off function will not operate while the
amp is connected to a computer with a USB cable.
Tip
As the factory default setting, the auto power-off function is enabled.
Enabling/disabling the auto power-off function
1.
While holding down the TAP button, turn on the amp. The PROGRAM/
TUNER LED shows the current setting.
Enabled
Disabled
2.
Press the TAP button to switch between enabling and disabling the function.
3.
Wait without performing any operation for a few seconds. The setting is
applied, and the amp automatically returns to normal operation.
Preset programs and user programs
To recall a preset program, turn the AMP selector when the PRESET LED below
PROGRAM lights up. Regardless of the position of each knob, a preset program
for a sound typical of each amp model will be recalled.
You can also adjust the amp and effect settings to create a sound that can be
saved as user program A or B. The saved program can be recalled by pressing
the PROGRAM button.
Regardless of the program, the sound level will reflect the current position
of the POWER LEVEL knob.
Manual mode
When the PROGRAM button is pressed until the PROGRAM LED goes off, the
amp enters manual mode, where the setting positions of all knobs are applied
directly to the sound.
Saving a program
After adjusting the various knobs and buttons on the top panel to create your
desired sound, it can be saved (written) as a user program.
Tip
The saved sound can be recalled with the PROGRAM button.
1.
Hold down the PROGRAM button for at least 0.5 second. The LED for either
USER A or B blinks to indicate the location where the program will be saved.
2.
Press the PROGRAM button to select the save location.
Tip
To cancel the write operation, press the TAP button.
3.
Hold down the PROGRAM button for at least 2 seconds (until the LED
changes from blinking to lit). The program is saved at the selected location,
and the saved program is selected.
Any program previously saved at that location is overwritten.
If you switch to another program or turn off the amp before saving the
sound that you are creating, the changes that you made will be lost.
Restoring the factory settings
Here’s how to restore all settings of the VX50 GTV/VX15 GT to their factoryset
state.
Performing this operation resets all user programs that had been saved as
well as all settings, such as the delay time in manual mode and whether the
auto power-off function is enabled or disabled, to the factory defaults.
1.
Turn off the power.
2.
While holding down the PROGRAM button, turn on the amp. After the
USER A and B LEDs blink, release the pressed button.
Tip
If you decide to cancel initialization at this point, press the TAP button.
3.
Hold down the PROGRAM button for at least 2 seconds (until the LED
changes from blinking to lit).
Initialization is completed, and the amp returns to normal operation.
Never turn off the power while initialization is in progress.
Using the tuner
The tuner function lets you tune a guitar that’s connected to the INPUT jack. With
this tuner function, the pitch of the input is measured, and the difference with the
reference pitch (E) is indicated by the PROGRAM/TUNER LEDs.
1.
Hold down the TAP button for at least 1 second. All effects are bypassed,
and the tuner function is turned on.
2.
Play the open 6th string on the guitar.
Be careful not to play any of the other strings.
3.
Tune the string until only the center green LED of the three LEDs lights up.
Tip
This tuner will also detect E in a different octave. It can also be used for tuning
using harmonics or for tuning other instruments, such as a bass guitar.
Flat
Slightly flat
In tune
Slightly sharp
Sharp
4.
Press the TAP button to stop tuning and cancel bypass.
Tip
After using the tuner to tune the 6th string to the reference pitch, tune the other strings
based on the 6th string.
Using a foot switch
If an optional foot switch (sold separately) is connected to the FOOT SW jack on
the rear panel, you will be able to switch programs using your foot.
You must connect or disconnect the foot switch while the power is off. Mal
-
functions or damage may occur if you connect or disconnect the foot switch
while the power is on.
Do not connect any foot switch other than the VOX VFS2 or VFS5. Other-
wise, a malfunction or damage may occur.
Do not press two or more foot switches simultaneously. Doing so may cause
malfunctions.
VFS2
When the VFS2 is connected, you can switch between
user programs A and B (USER A and B).

onds, the program is saved at the
same time that the save location
is selected.
Setting time by tapping (CH1 to CH4 switches)
Press the switch with the same number as the selected program to set the time
for delay/reverb effects. The interval between two presses of the switch will be
set as the time.
Connecting to a computer via USB (VX50 GTV only)
The VX50 can be connected to a computer, tablet, smartphone, etc. by using a
commercially available USB cable. Once connected, the amp can be used as a USB
audio interface, or users can access our Tone Room editor/librarian software to
manage and customize amps and effects.
In order to connect to an iOS device (iPad or iPhone), a commercially avail-
able adapter, such as the Apple Lightning to USB camera adapter, will be
required.
In order to connect to an Android device, a commercially available USB On-
The-Go (OTG) connector will be required. In addition, the Android device
must be running Android 6.0 or later in order to use Tone Room.
The input to the AUX IN jack is not output to the USB port.
