V-AMPIRE LX1200H/LX210
6.2.3 Combinations of effect algorithms
(multi-effects programs)
PHASER & DELAY: Phaser and delay combined.
FLANGER & DELAY: Here the input signal is delayed and
processed with a pronounced wave-like effect. It is particularly
effective for highlighting single notes, but can also be used to
make solos more interesting.
CHORUS & DELAY: This algorithm combines signal delay with
the popular chorus effect.
CHORUS & COMP: Incredible sustain effects can be produced
with the compressor. This is especially useful for sustaining
individual guitar notes. Combined with chorus, it can make the
audio signal extremely dense.
6.2.4 Special effects
COMPRESSOR: A compressor limits the dynamic range of the
audio material, thus producing audible and creative sound effects.
Pronounced use of the compressor (using the EFFECTS control)
allows you to compress the overall dynamic range of the material.
AUTO WAH: 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. In American
funk music of the 70s you can hear auto-wah effects used in a
variety of applications. The auto-wah alters its filter frequency
automatically depending on the signals magnitude, rather than
being controlled by the position of a pedal.
TREMOLO: Simulates the classic Fender Tremolo. It has
returned to popularity with trip-hop.
ROTARY: This is the quintessential simulation of the classic
organ effect normally produced by speakers rotating at slow or
fast speed in an extremely heavy speaker cabinet. This effect
uses the physical principle of the Doppler effect to modulate the
sound.
NOISE GATE: 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.
6.3 The separate reverb effect
The reverb effect is independent of the multi-effects processor
and can be added to the mix signal at any time. To edit the
REVERB function, press button D in EDIT mode (pressing the
two arrow buttons simultaneously) and use the two arrow
buttons to select one of the nine different reverb types available:
1 Tiny Room
2 Small Room
3 Medium Room
4 Large Room
6Small Spring
7 Medium Spring
8 Short Ambience
9 Long Ambience
Simulates the early reflections of a
reverbless room
5Ultra Room
Special effect transforming guitar signals
into heavenly pad sounds
Simulations of typical spring reverbs
Classic room simulation featuring various
room sizes from bathroom to cathedral

7. TUNER
Press the TUNER button to activate the built-in tuner.
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 220 Hz. When you plug your guitar into the
device 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 claritys sake, lets
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). Todays
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 V-AMPIRE 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 the
TUNER button and switch to EDIT mode by pressing the two
arrow buttons simultaneously. The display will show 40, which
means 440 Hz. Use the arrow buttons 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. For example, if you
start with a reference pitch of 440 Hz and press the right-hand
arrow three times, the display will read 43, i.e. 443 Hz. To quit
EDIT mode, press either the TUNER or the TAP button. Any
changes will be stored automatically. The tones for the other
strings on your guitar will automatically be adjusted to the new
reference pitch.
