RACKTUNER BTR2000 User Manual
1. Introduction
1.1.2 Initial operation
Thank you for the confidence you have placed in us with your
purchase of the BTR2000. You have acquired an extraordinary
combination of a tuner and a metronome with integrated rack
lighting that also makes it perfect for on-stage use.
This advanced equipment sets new standards with its extensive list of
features. It is an auto-chromatic tuner, which means it can automatically
recognize any pitch when tuning your instrument. It also offers
3 individually configurable functions in tuner mode:
• With 11 different modes, the tuner lets you respond fully to the
specific needs of your instrument. For example, in guitar mode
the BTR2000 recognizes the pitches of the open guitar strings,
while in chromatic mode it recognizes all 12 half-tones.
• The standard “A” pitch can be calibrated individually. This makes
the tuning of your instrument even more flexible.
• To achieve a particular sound or to allow you to play better
with other instruments (such as brass), the RACKTUNER lets
you transpose your instrument by half steps, tuning it higher
or lower. This way you can be fully responsive to the unique
features of both the music and your instrument.
In addition to its function as a tuner, the BTR2000 can also be used
as a metronome. You can set the BPM rate manually or use the
TAP function.
With its well-engineered circuitry, the RACKTUNER can be used with
one or two amplifiers, so that you can adapt the BTR2000 for use
in many different settings, where it will provide optimal support in
any situation.
Be sure that there is enough space around the unit for cooling.
To avoid overheating, please do not place the VINTAGER near radiators
and other equipment emitting heat.
The BTR2000 features a shockproof housing to ensure safe operation
without requiring separate grounding.

2. Control Elements and Connections
This chapter describes the different control ele­ments of your BTR2000.
All of the buttons and connectors are explained in detail with useful
information on how to make the most of them.
Most of the buttons on the RACKTUNER have a dual function.
The different functions on each button are distinguished by how long
the button is held down when pressed.
The RACKTUNER’s operating mode—tuner or metronome mode—also
determines button function.
There are one or two LEDs above each button. They correspond to the
functions of the buttons. For example, either the “1” or “2/MIC” light is
always on above the INPUT SELECT (9) button. The “MUTE” LED on
the other hand only lights up when the MUTE button (8) is pressed to
turn off the sound of the unit.
◊ When you switch to metronome mode, the LEDs for the
tuner mode are turned off.

4. Tuner
The BTR2000 tuner lets you control several parameters:
• There are 11 different tuner modes.
• The standard “A” pitch can be calibrated individually.
• You can transpose the pitch if desired.
This lets you set the optimal configuration for any purpose.
◊ When the BTR2000 is first switched on or when no functions
are selected, the display shows the following: ---. Once a
button has been pressed to select a function, the display
shows the values that have been set.
4.1 Instrument tuning
There are several ways to use the BTR2000 to tune your instrument:
• You can tune an instrument plugged into the input connector by
using the tuning display.
• If the instrument is not connected to the BTR2000, you can tune
it using the built-in microphone.
• You can also tune an instrument using a reference tone emitted
by the BTR2000.
4.1.1 Tuning with an instrument plugged in
1.
Plug your instrument into one of the INPUT connectors on the
front or rear panel of the unit (see chapter 3).
2. Press the INPUT SELECT button to select the input your
instrument is plugged into. The 1 or 2/MIC LED will light up
depending on which input is selected.
3. Select the tuner mode you wish to use (see chapter 4.2).
◊ The BTR2000 only recognizes and displays certain pitches
depending on the selected tuner mode.
4. Calibrate the reference tone and set the transposition if desired
(see chapter 4.3 / 4.4).
5. Play a note on your instrument (generally an open string).
The tuner is set to recognize the frequency of the pitch.
6. The display will show the name of the note closest to the
frequency you have generated.
◊ The unit displays the note that is available in this mode and
comes closest to the frequency played.
◊ In chromatic mode the BTR2000 can recognize half-tones.
These are indicated by a “b” in the display.
For example, a note that is played and identified on the display as
“A” may deviate somewhat from the ideal pitch. The LED bar clearly
indicates this deviation.
7. Using the LED bar, you can monitor how far and in what
direction your note deviates from the ideal. If the display tends
to the left, the note played is somewhat flat and if the LEDs tend
to the right your note is too sharp.
◊ The LED bar on the BTR2000 can indicate deviations up
8.
9.
to 50 cents (a quarter tone) sharp or flat. If the incoming
frequency deviates more than this from the displayed note,
the LED display either remains on the far left or right or
jumps to the next note.
Tune the string of your instrument until the green light in the
center of the LED bar lights up.
Repeat steps 5 through 8 for all of the strings of
your instrument.
4.1.2 Tuning with the built-in microphone
◊ To be able to work with the built-in microphone, there must
1.
2.
3.
4.
be no cable plugged into the INPUT 2 connector in the back
of the BTR2000 and the MUTE button must be depressed.
Select INPUT 2 with the INPUT switch on the front of the
BTR2000. The 2/MIC LED lights up.
Mute this channel by pressing MUTE/LIGHT; the MUTE LED above
the MUTE/LIGHT button lights up. The built-in microphone is
now activated and ready for use.
Position your instrument as close as possible to the BTR2000.
Make certain that there is as little noise as possible to disrupt
the tuning process.
Tune your instrument as described in steps 3 through 9 in
chapter 4.1.1.
4.1.3 Tuning with a reference tone
The BTR2000 can generate and output notes. You can then tune your
instrument by ear without an optical display.
◊ If your instrument is plugged into INPUT 1, the reference
tone is output only through the SOUND output connector;
if it is plugged into the INPUT 2 connector and there is
nothing plugged into the SOUND output, the reference
pitch is played through the MAIN output together with the
instrument signal.
1. Select the tuner mode you wish to use (see chapter 4.2).
◊ The BTR2000 can only recognize certain pitches depending
on the tuner mode selected.
2. Calibrate the reference tone and set the transposition if desired
(see chapter 4.3 / 4.4).
3. Briefly press the SOUND/METRONOME button.
The sound mode is activated and the SOUND LED above the
SOUND/METRONOME flashes. The display shows the volume level
currently set (1 , 2, ... 12).
4. The unit emits the lowest pitch available in this mode or the
last pitch set in the tuner (even if it is not available in the
currently selected tuner mode) through the SOUND and/or MAIN
connector on the back panel of the BTR2000.
5. The volume of the reference tone can be set with the wheel.
6. After briefly pressing the TRANSPOSE/REF button you can turn
the wheel to change the reference tone emitted depending on
the selected tuner mode. During this adjustment the TRANSP
and SOUND LEDs are illuminated.
7. After a short time or after the TRANSPOSE/REF button is pressed
again, the unit returns to sound mode and the wheel can again
be used to control the volume.
8. Tune each string of your instrument to an appropriate
reference tone.

RACKTUNER BTR2000 User Manual
When you press the MUTE button, the MAIN output
(instrument sound and possibly the reference tone as well) is muted;
the SOUND output is not affected.
To exit sound mode, briefly press the SOUND/METRONOME button again.
The SOUND LED will go out and the tone will no longer be emitted.
◊ When it is switched off, the BTR2000 stores the selected
tuner mode.
The names of the notes are shown on the display as follows:

4.2 Selecting tun er mode
The open strings on each instrument (e.g. guitar, bass, ukulele)
are tuned differently. It is also possible to deliberately tune an
instrument such as a guitar to a so-called “open tuning” to make it
easier to play in a particular key. The BTR2000 provides a tuner mode to
suit many different purposes so you can optimally tune your instrument.
Depending on which of the 11 tuner modes you select, the tuner only
recognizes specific pitches:
Chromatic (chr)
The tuner can recognize all 12 half-tones of a scale. (C - C sharp - D - D
sharp - E - F - F sharp - G - G sharp - A - B flat - B)
Guitar (GUI)
The tuner recognizes the pitches of a 7-string guitar.
(B - E - A - D - G - B - E)
Tab. 4.1: Note display
Bass (BAS)
This mode is especially well suited for a 6-string bass.
(B - E - A - D - G - C)
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). Today’s 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.
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.
4.3 Calibrating the tuner
4.3.1 Manual calibration
The pitch of the standard “A” is set to a particular frequency using the
BTR2000 control panel.
1. Depress the TRANSPOSE/REF button for at least two seconds.
The ≠ 440 LED flashes. The display shows the frequency
currently set for the standard “A,” e.g. 440.
2. You can adjust the pitch of the standard “A” by up to 12 Hz
higher or lower by turning the wheel.
3. When you press the TRANSPOSE/REF button again for at least
two seconds, the unit saves the frequency you set for standard
“A,” the frequency is no longer displayed and the ≠ 440 light
stops flashing.
4. If the pitch of the standard “A” is other than 440 Hz,
the ≠ 440 LED above the TRANSPOSE/REF button lights up.
4.3.2 Automatic calibration
The BTR2000 recognizes a pitch played on an instrument plugged into
the unit or into the integrated microphone. The corresponding “A” is
determined and stored.
9
RACKTUNER BTR2000 User Manual
◊ Any note can be played for the automatic calibration.
Connect your instrument to an input of the BTR2000. You can
also use the built-in microphone (select INPUT 2 and press the
MUTE button).
2. Depress the TRANSPOSE/REF button for at least two seconds.
The display shows the frequency currently set for the standard
“A” and the ≠ 440 light flashes above the TRANSPOSE/REF
button during the entire process.
3. Turn the frequency all the way down (to the left) with the
wheel. After the lowest possible frequency for the standard “A”
(428 Hz), auT appears on the display, automatic calibration is
activated and the unit waits for an input frequency.
4. Play a note. The display shows the name of the note closest to
the one you played. The LED bar indicates the deviation from the
displayed note. If this is unsatisfactory, you can play the note
again. You can cancel the calibration by pressing and holding
the TRANSPOSE/REF button.
◊ If the input note is too unstable or too soft, the automatic
calibration cannot proceed.
5. If the note is satisfactory and the display in the LED bar is stable,
you must briefly press the TRANSPOSE/REF button. The BTR2000
stores a standard “A” pitch that is attuned to the note you
played. The frequency of this “A” is displayed.
6. The calibration is completed by pressing and holding the
TRANSPOSE/REF button. If you do not hold the button long
enough, the calibration process restarts.
7. If the pitch of the standard “A” is other than 440 Hz,
the ≠ 440 LED above the TRANSPOSE/REF button lights up.
In order to change the frequency of a stored standard “A,” press the
TRANSPOSE/REF button for at least one second and adjust the
frequency using the wheel.

For certain applications, it may be useful to shift the tuning of the
instrument by a few half-tones.
Easier interplay with other instruments
Say a song needs to have brass accompaniment. While pieces in a flat
key (such as F major (1 flat), B flat major (2 flats) and C minor (3 flats))
are especially well suited to brass, many guitarists and bassists are
not very comfortable playing in these keys. There are several options
for playing such pieces:
• The guitarist and bassist play the complicated fingerings of the
flat keys.
• These two players’ instruments are tuned (transposed) so that the
easier fingerings of a different key (e.g. C major or G major) can be
used to produce the correct chords in the actual key of the piece.
Achieve a specific sound
With a different tuning, the tension on the strings is different.
This change creates different overtones when the strings are played,
giving the instrument a different sound.
The BTR2000 lets you complete such a transposition easily
and accurately.
1. Briefly press the TRANSPOSE/REF button. The TRANSP light
flashes and the display shows the trans­position currently set
(0, if no transposition is set).
3.
4.
Turn the wheel to transpose up to 7 half-tones higher or lower.
The display indicates the number of half-tones by which a nontransposed instrument is too high (1 , 2, ..., 7) or too low
(-1, -2, ..., -7), when compared with the BTR2000 transposition.
You can exit this menu by pressing the TRANSPOSE/REF
button again.
When a transposition is set, the TRANSP LED above the
TRANSPOSE/REF button lights up.
Example
A piece should be played in F major. This key has 1 flat, and thus it has
several complex fingerings. You want to retune the guitar so that you
can use G major fingerings to play F major chords. To do this, you must
transpose the instrument down 2 half-tones.
• To set the transposition, briefly press the TRANSPOSE/REF button.
The display still shows the number 0 (no transposition set).
• Turn the wheel so that the display shows the number 2
(2 half-tones higher). Now your instrument is tuned 2 half-tones
above the tuner and must be tuned down.
◊ When a transposition has been set, the TRANSP LED above
the TRANSPOSE/REF button lights up.
• Select a tuner mode (chapter 4.2) and tune all strings of your
instrument as described in chapter 4.1.
• When the tuning process is finished, the fingering for a G major
chord plays an F major chord.
◊ The calibration settings are stored even if you switch the
BTR2000 off.
To turn off the transposition, press the TRANSPOSE/REF button and
turn the wheel until the display indicates a transposition up/down or
0. The TRANSP light goes out.
4.5 Setting your own tempering
The topic of “tempering” is a very interesting and extensive one. It has
been much studied scientifically and this knowledge gives you many
ways to work with the specific characteristics of your instrument and
individual pieces.
This topic can only be touched upon here. You can find
more exciting information about this at our website at
behringer.de (behringer.com).
Equal tempering
The pre-set tuner modes of the BTR2000 are all based on an equal
tempering. This means that only the octave interval is exactly
right (frequency doubling); to generate other intervals, the octave
is divided into 12 equal half steps, which make up the individual
intervals (e.g. a fourth = 5 half steps). However, the resulting
intervals do not correspond entirely to the ideal intervals
(intervals of a natural scale); each interval is slightly out of tune.
At any rate, these deviations are barely audible and are thus not
perceived as dissonant.
This type of tuning is nevertheless a compromise, but it enables all
keys to be played with just one tuning.

RACKTUNER BTR2000 User Manual
Custom tempering
The BTR2000 tuner makes it possible to tune using different
temperings, whether existing or customized. This means that some
strings are tuned a few cents higher or lower according to a certain
system. The scale of the LED bar can be changed from ±50 cents to
±10 cents. This enables extremely precise tunings since each light in
the bar corresponds to exactly 1 cent.
◊ Before starting fine tuning, you should first tune your
instrument as described in chapter 4.1.
1. To change the scale of the LED bar, press and hold the
MODE/FINE button. If the “±10 Cent” display is selected,
the FINE light above the MODE/FINE button lights up.
2. Tune your instrument as described in chapter 4.1. Now you can
see the smallest deviations from the pre-set pitch on the LED
bar and adjust them with complete confidence.
5.3 Acoustic and visual BPM indicator
5. Metronome
Acoustic indicator
The selected tempo is also output at the SOUND or MAIN connector.
◊ If your instrument is plugged into INPUT 1, the metronome
click is output only through the SOUND connector. If it is
plugged into INPUT 2, and the SOUND output is not in use,
the metronome click is output together with the instrument
­signal from the MAIN connector.
You can change the volume of the click at any time and thus control
the volume ratio between instrument and click if you are listening to
both using one amp.
1. Briefly press the SOUND/METRONOME button. The SOUND LED
above the button lights up.
2. With the wheel you can adjust the volume of the click with
12 volume levels.
◊ Even at the lowest volume level 1
( ), the metronome click is
still audible. The click can be shut off with the MUTE button.
3. If the volume is not changed for some time or if the SOUND/
METRONOME button is pressed again, the SOUND light goes out.
The metronome can naturally be muted without affecting the
visual display.
1. Press the MUTE/LIGHT button.
2. The metronome click is muted and no longer output through the
MAIN connector.
The integrated metronome in the BTR2000 has a range of 30 beats
per minute (BPM) to 240 BPM. There are essentially 2 ways to use
the metronome:
• You can pre-set a tempo (e.g. 60 BPM).
• The BTR2000 can pick up a tempo set by you.
To use the metronome, the BTR2000 must be in metronome mode:
1. Press and hold the SOUND/METRONOME button for 2 seconds.
2. The metronome ­function is selected when the METR light above
the button is lit.
3. Briefly press INPUT SELECT; the click and the optical display of
the metronome start up.
◊ The metronome values set most recently (BPM, type of
graphic display, click volume, MUTE) are stored when the
BTR2000 is turned off.

3.
4.
5.
Set the BTR2000 to metronome mode (press and hold the
SOUND/METRONOME button for 2 seconds).
The selected BPM rate appears in the display.
You can adjust the BPM rate using the wheel.
Briefly press the INPUT SELECT button. The metronome starts up.
The selected tempo appears in the display and is indicated
optically and acoustically.
5.2 Using the TAP function
1.
Set the BTR2000 to metronome mode (press and hold the
SOUND/METRONOME button for 2 seconds).
2. Press the TAP button at least 4 times in succession in the desired
tempo. During your entry, the letters tap appear in the display.
3. The BTR2000 metronome takes this tempo and displays
it in BPM.
◊ If the TAP button is pressed fewer than four times,
the metronome returns to the last set value after 2 seconds.
4. If necessary, the tempo can be readjusted after setting using
the wheel.
5. Briefly press the INPUT SELECT button. The metronome starts up.
6. The detected tempo is indicated visually and acoustically.
Visual display
The BTR2000 has two ways of indicating the selected tempo on the
LED bar:
• A flashing light indicates the tempo.
• A light moves constantly from one side to the other
with the beat. This simulates the needle of a standard
mechanical metronome.
You can toggle between these two display types as follows:
1. Set the BTR2000 to metronome mode (press and hold the
SOUND/METRONOME button for 2 seconds).
2. Start the metronome by pressing the INPUT SELECT button.
3. Briefly press the MODE/FINE button to toggle between the two
display types.
