Special Effects; Reverb; Tuner; Tuning Your Guitar - Behringer X V-AMP User Manual

The American funk in the ’70s proved that auto
wah had many possible applications. Instead of regulating the
filter frequency with your foot, our effect does this automatically,
depending on the signal level. In doing so, our effect is similar to
the EHX MuTron III in the up position.
The second parameter determines how quickly the filter is
shifted; the third parameter selects the effects block (1 - 4).
This is our attempt at replicating the legendary
MuTron III, and we succeeded! The most famous user of this
effect is probably Bootsy Collins. The MuTron III had an up/down
switch. Here, the effect resembles the MuTron in the down
position.
The second parameter determines how quickly the filter is
shifted, while the third parameter determines the effects block
(1 - 4).

6.1.3 Special effects

The legendary Wah Wah effect owes its fame
mainly to Jimi Hendrix. Describing it is certainly more difficult than
simply listening to Hendrix using it on Voodoo Chile.

Our simulation is based on the well-known
MXR Dyna Comp. A compressor limits the dynamic range of a
signal, in that the signal level is reduced as soon as a pre-
determined threshold is exceeded. A compressor lets you
achieve noticeable and creative sound effects. How strongly
the compressor kicks in is controlled using ADJUST, allowing
you to achieve apparent sustain). When ADJUST is turned all the
way to the left, the compressor function is deactivated.
The second parameter (attack) controls the amount of time
that the compressor needs to react, once the threshold has
been exceeded. If you set up a short attack time, the compressor
will react very fast.
Noise gates are used to remove or reduce
noise or other interference. Guitar signals in particular are very
sensitive to interference. Not only do guitarists often use high-
gain settings but guitar pick-ups can amplify unwanted inter-
ference. This can be painfully apparent during breaks in the
music. And how does a noise gate work? It simply mutes the
signal during breaks, eliminating any interference at the same
time.
The ADJUST control determines, when the noise gate starts
processing. This control lets you decide if you want to suppress
background noise more or less pronouncedly. When ADJUST is
turned all the way to the left, the noise gate function is deactivated.
The second parameter (release) determines the time that the
noise gate remains open after it had fallen below the threshold.
If you set up a short release time, this means that the noise gate
will suppress the signal very soon after it detects noise.

6.2 Reverb

The reverb is still one of the most important effects in a mix or
at a live event. BEHRINGER offers you four different reverb
programs, so that you can always find the kind of reverb that fits
your excact situation:
Ambience: short room simulation without reverb tail.
Cathedral: a long, rich reverb, like in a cathedral.
Spring: typical sound of a classic spring reverb.
Reverb: universal, warm reverb simulating a concert hall.
ADJUST controls the reverb intensity, while the second
parameter determines decay.
A/DAä, Bossä, DyTronicsä, Electro Harmonixä (EHX), MXRä, Digitechä, Voxä as well the
names of musicians and bands are registered trademarks of their respective owners and are in
no way associated with BEHRINGER. The brand names appearing here are mentioned solely to
describe the character of sounds and effects created in the X V-AMP.
The integrated tuner is activated/deactivated by simultaneously
pressing both footswitches. In doing so, the X V-AMP is switched
into bypass mode. Use ADJUST to modify bypass volume.

7.1 Tuning your guitar

The chromatic tuner automatically recognizes the frequencies
of all the standard guitar notes. For the a string this means a
frequency of 110 Hz. When you plug your guitar into the
X V-AMP and play an open string, the tuner will recognize and
display the note. Since the tuner uses an auto-chromatic scale,
it can also recognize semi-tones, which are shown with a “b” in
the display.
It may happen, however, that a note is displayed as “A” but is
actually slightly out of tune. This is shown by at least one of the
four LEDs at the foot of the display lighting up. In certain cases
even two of the LEDs may light up, which indicates that the pitch
of the note played lies between the pitches represented by the
two LEDs. When the circular tuner LED in the middle lights up,
this means the note played is in tune.

7.2 Setting reference pitch “A”

To give you maximum freedom for tuning your guitar, you can
change the preset reference pitch “A”. For clarity’s sake, let’s
look at this in more detail.
The so-called concert pitch “A” has been raised steadily over
time. For example, the tuning forks used by Bach, Händel or
Mozart were 415, 420 or 421 Hz (oscillations per second). Today’s
orchestras tune to “A” at 444 Hz, and the Berlin Philharmonic
Orchestra lead the field with their own concert pitch “A” at
447 Hz.
The reference “A” on your X V-AMP has been factory-
programmed at 440 Hz. If you are going to play with a big orchestra
tuning their instruments to a reference pitch of 444 Hz, you will
need a function that allows you to change your reference pitch.
To activate this function, switch on the tuner by pressing both
footswitches simultaneously. Then, keep TAP pressed down to
start calibrating the tuner. The display will show “40”, which
means 440 Hz. Use ADJUST to raise or lower the reference
pitch by up to 15 Hz. The display always shows the last two
digits as the first digit is always 4. To quit, simply release TAP.
Any changes will be stored automatically. The tones for the
other strings on your guitar will automatically be adjusted to the
new reference pitch.
