ton is pressed, the metronome starts and
“” will appear on the display.
The TM-50 can use the tuner and metronome
simultaneously.
The TUNER ON buon and the MET-

9
bag. To turn the device on or o, push in
the power buon.
Turning the tuner off
When the tuner is in use, press the TUNER
ON buon to turn o the power. The tuner
will also turn o automatically if it’s not in
use for twenty minutes.
Turning off the metronome
When the metronome is in use, press the
METRONOME ON buon to turn o the
power. The metronome will also turn o au-
tomatically if not in use for twenty minutes.
Connections
If you want to connect an
instrument or contact mic etc
If you want to tune an instrument with a
pickup, such as an electric guitar, connect a
cable to your instrument, and plug the cable
into the TM-50’s INPUT jack.
The INPUT jack is only for a 1/4" mono
cable. Stereo (TRS) cables cannot be used.
If you want to tune your instrument using a
Korg contact mic (separately sold), plug the
contact mic into the TM-50’s INPUT jack.
If a device is not connected to the INPUT
jack, tuning will be performed by the
internal mic.
Connecting headphones
You can connect headphones with a 1/8"
mini-plug to the PHONES jack.
When plugged in, no sound will be heard
from the speaker. Use the volume control to
adjust the volume of the headphones output.

Using the tuner
Tuning while watching the meter
(Meter mode)
1. Connect your instrument cable or contact
mic to the TM-50’s INPUT jack.
If a device is not connected to the
INPUT jack, tuning will be performed
by the internal mic.
2. Press the TUNER ON buon.
“” will appear at the top
of the display and the calibration (refer-
ence pitch) will be displayed below that.
3. To change the calibration, press the
CALIB/NOTE p or q buon.
The calibration value increases and
decreases in units of 1 Hz. By pressing and
holding these buons, you can increase or
decrease the value continuously. This set-
ting is stored even when the power is o.
4. Play a single note on your instrument.
The closest note to the input sound will
appear in the center of the display. Tune
your instrument to the correct pitch, so
that the desired note name appears.
If you’re using the internal mic, place
your instrument as close as possible
to the mic so that extraneous sound is
not picked up while tuning.
5. While playing a single note on your
instrument, tune your instrument so that
the tip of the meter indicates “q” and
the center indicator of the tuning guide
is lit up.
The le tuning guide indicator will light
up if the pitch of your instrument is at,
and the right indicator will light up if the
