RACKTUNER BTR2000
Bass (
BAS
)
This mode is especially well suited for a 6-string bass. (B - E - A - D - G - C)
Baritone (
brt
)
This setup helps you tune a guitar to a baritone tuning, in which each string is tuned 5 half-tones (a
fourth) lower than a normal guitar. (B - E - A - D - F sharp - B)
Banjo (
bjo
)
The very widely used banjo tuning is made possible with this mode. (G - D - G - B - D)
Ukulele (
ule
)
The BTR2000 recognizes the notes of the open strings of a ukulele. (G - C - E - A)
Open D (
o-d
)
The open strings are tuned so that they create a D major chord. (D - A - D - F sharp - A - D)
Open E (
o-E
)
The open strings are tuned so that they create an E major chord. (E - G sharp - E - G sharp - B - E)
Open G (
o-G
)
All open strings create a G major chord. One good variant of this is the following tuning:
G - B - D - G - B - D. Since the low strings are under very high tension in this tuning, the strings can also
be tuned as follows: D - B - D - G - B - D
Open A (
o-A
)
The tuner recognizes only the notes of an A major chord. (E - A - C sharp - A - C sharp - E)
DADGAD (
dad
)
In this mode, the tuner recognizes the following notes: D - A - D - G - A - D.

When it is switched off, the BTR2000 stores the selected tuner mode.
The names of the notes are shown on the display as follows:

4.3 Calibrating the tuner
To give you every available option for tuning your instrument, you can change the setting of the
standard A pitch. In order to clarify what this involves we will take a slight digression.
The so-called standard A pitch has risen over time since its initial measurement: The tuning forks
used by Bach, Händel or Mozart were at 415, 420 or 421 Hz (cycles per second). Todays orchestras
tune to an A of 444 Hz. The Berlin Philharmonic is right at the forefront: their standard A is 447 Hz.
The pitch of the standard A on the BTR2000 is set at the factory to 440 Hz. In the event you want to
play with a major orchestra that tunes to a standard A of 444 Hz, you need a function that will let you
change the frequency of the A.

The calibration settings are stored even if you switch the BTR2000 off.
