V-AMPIRE LX110
8. INSTALLATION
7. TUNER
The built-in tuner can be switched on and off by pressing the UP
and DOWN buttons simultaneously. This switches the V-AMPIRE
to bypass mode.
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
V-AMPIRE 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 semitones which are indicated with the flat
symbol “b” in the display.
However, it may happen, for example, 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 bottom of the display lighting up. In
certain cases even two of the LEDs may light up indicating 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, then the note played is in tune.
7.2 Setting reference pitch “A”
To give you maximum freedom when 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 resonated at 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 V-AMPIRE has been factory-
programmed at 440 Hz. If you are going to play with a big orchestra
that tune their instruments to a reference pitch of 444 Hz, you
will need a function that allows you to change your reference
pitch:
V Switch on the tuner by pressing the UP and DOWN buttons
simultaneously, then press and hold the ADJUST control to
enter the calibration mode: The display shows “40”, i.e. 440
Hz.
V Press and turn the ADJUST control to increment/decrement
the reference tone “A” by 15 Hz each. The display always
shows the last two digits of the basic tone, given that the
first digit is always “4” (“44” = 444 Hz, etc.).
V Release the ADJUST control to quit the calibration mode.
Any changes made are stored automatically. The remaining
strings of your guitar are now tuned on the basis of the
adjusted reference tone.
7.3 Tuner Bypass volume
In tuner mode, the ADJUST control adjusts the volume of the
guitar signal while tuning up. Turning the control fully left mutes
the signal.
8. INSTALLATION
The inputs of the BEHRINGER V-AMPIRE are on 1/4" TS
