Vox AV15 Manuel D'utilisation page 4

Introduction
Thank you for purchasing the VOX AV15 analog valve amplifier. To help you get the
most out of your new instrument, please read this manual carefully.
Main Features
- Our constant R&D of analog designs has enabled us to create a whole new cat-
egory of analog modeling guitar amplifiers. This research allows us to create the
sound of legendary tube guitar amplifiers.
- The Pre-amp is powered by a 12AX7(ECC83) tube. This delivers a more dynamic
and harmonically rich sound. For greater flexibility, you can change some tube
parameters to really customize your tone.
- The Power-amp also includes a 12AX7(ECC83) tube, allowing for real tube power
amp distortion, even at lower wattage levels. Like the pre-amp, you can also
change tube parameters in the power-amp, for greater flexibility.
- There are 3 types of analog voiced digital effects included. Each one can be used
independently.
- The AUX IN allows you to plug in your own portable music player, so you to jam
along with your favourite tracks. Plug your headphones into the PHONES jack,
for silent practice. This output is powered by an analog cabinet simulator, giving
the real feel of a guitar amplifier.
Making connections
1.
Turn the POWER LEVEL knob on the amp to the minimum position.
2.
Connect the included AC adapter to the DC12V jack, 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.
The tubes may produce a noise until they have warmed up, or a popping noise
may be produced when the PREAMP CIRCUIT selector is turned. These are
not malfunctions.
Auto power-off function
The amp has an auto power-off function. With this function, the amp is automatically
turned off if there is no 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.
When the input level is extremely low or there is very little change in the sound,
the auto power-off function may be activated. In addition, depending on the set-
tings and environment, the amp may interpret noise as input, even if the guitar is
not being played.
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 DELAY button, turn on the amp. The EFFECTS button
shows the current setting.
