4. TUNER
The BTR2000 tuner lets you control several parameters:
s There are 11 different tuner modes.
s The standard A pitch can be calibrated individually.
s 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:
s You can tune an instrument plugged into the input connector by using the tuning display.
s If the instrument is not connected to the BTR2000, you can tune it using the built-in microphone.
s 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 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.
8. Tune the string of your instrument until the green light in the center of the LED bar lights up.
9. Repeat steps 5 through 8 for all of the strings of your instrument.
