Tuning procedure
On the DTR-1000 you can use the tuning meter to perform chromatic tuning.
On the DTR-2000 you can use the tuning meter or a reference pitch to tune in
eight different modes (refer to "Tuning modes" on the following page).
Tuning may not be possible if your instrument has an excessively high output
level. In this case, lower the output level of the instrument that you are tuning
Connections
If you want to tune an electric guitar or bass, plug it into the INPUT 1, 2 jack.
The DTR-2000 has INPUT 1 and 2 jacks. Use the INPUT SELECT switch to
select the jack that you are using.
If you want to tune an acoustic instrument, use a contact mic (CM-100: sold
separately).
On the DTR-2000 if you use the INPUT SELECT switch to select the unused
INPUT jack and then turn Mute on, you will be able to tune using the built-in mic.
If you use the internal mic, place your instrument as close to the DTR-2000's
mic as possible. Also be careful that the mic does not pick up sounds other than
the instrument that is being tuned.
Tuning with the meter
1. Use the DISPLAY switch to select the type of tuning meter display.
CENT display
The display will show a range of -50 cents–+50 cents. Tune your instrument
so that the 0 (
▲ ) in the center of the meter is lit.
STROBE display
Tune your instrument so that the bars in the meter stop moving.
DTR-2000 only: Hz display
The display will show a range of -6 Hertz–+6 Hertz. Tune your instrument so
that the 0 (
▲ ) in the center of the meter is lit. If the pitch of your instrument is
outside the range of the display, the meter will be darker.
2. As necessary, change the calibration or flat settings.
On the DTR-2000 you can also select the tuning mode.
3. Play a single note on your instrument.
