RACKTUNER BTR2000
DEUTSCH
4.1.2 Tuning with the built-in microphone
+ To be able to work with the built-in microphone, there must be no cable plugged into the
INPUT2 connector in the back of the BTR2000 and the MUTE button must be depressed.
1. Select INPUT 2 with the INPUT switch on the front of the BTR2000. The 2/MIC LED lights up.
2. 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.
3. 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.
4. 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.
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.
4.2 Selecting tuner 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)
