Vertical-design and superior visibility

The Korg OT-120 chromatic band and orchestral tuner is intended for
orchestral instruments, packing precise performance and sophisticated
functionality in a vertical design that's easy to hold and operate. The
Korg OT-120 features a dual-display, an easy-to-see needle-type
indicator and a backlit LCD screen that shows the battery life, sound
output level, calibration, as well as key and note name. Additional
design features include a large dial that makes it easy to select the
desired mode, soft-touch buttons and a rear-mounted stand that lets the
band and orchestral tuner stand by itself. A sophisticated silver
aluminum panel contributes to its sleek, new look.

Accurately tune orchestral instruments over a wide range

Since we developed the world's first meter-type tuner in 1975, the
accuracy of Korg tuners has made them the choice of artists in all
styles of music. With its wide tuning range extending from A0 to C8, the
OT-120 lets you quickly tune any type of band instrument including,
orchestra, wind, string, brass or piano. The Korg OT-120 also provides a
wide range of calibration to support concert pitches in a range of
349-499 Hz (1 Hz steps).

Smooth and precise tuning you expect from a needle-type meter

This band and orchestral tuner uses a high-precision needle-type meter
to accurately indicate any pitch discrepancy. The speed at which the
needle responds to the input can be changed over a range of three steps;
you can choose fast, medium or slow speeds to match your tuning
preference. You can also choose from two tuning modes; Auto mode, which
automatically detects the pitch of a single note you play on your
instrument, or Manual mode, which lets you specify the desired note
name. In Manual mode, the needle movement is shown in a range of 50
cents, letting you view the tuning discrepancy over a wide range. In
addition to the excellent visibility unique to a needle-type meter, the
LEDs located below the meter also indicate pitch deviation or a perfect
match, making precise tuning easy even in dim locations.

Sound Back mode provides a reference tone that's ideal for tuning string
or wind instruments

The OT-120 produces a reference tone in a five-octave range extending
from C2 (65.41 Hz) to C7 (2093 Hz). You can switch the output level in
two stages. The large speaker allows for more volume while not being
obstructed even when using the stand, ensuring that the reference tone
is clearly audible.

The OT-120 also provides Korg's proprietary Sound Back mode. This mode
lets you connect an optional CM-100L contact microphone to the input
jack, and automatically make the OT-120's speaker produce a reference
tone for the note that is closest to the input pitch you play on your
instrument. The meter will also indicate the input pitch, letting you
tune using your eyes as well as your ears for greater accuracy - and
also providing a great way to train your sense of pitch.
Support for transposing instruments and historical temperaments
For conveniently tuning any wind instrument, twelve types of transposing
keys are provided in this band and orchestral tuner, including both
sharps and flats. The Multi Temperament function provides eight presets
that cover the most popular historical temperaments often used with
period instruments. These are also ideal for checking unique
temperaments used in classical music.

Long battery life

The OT-120 is designed for an extended battery life of approximately 100
hours when running on two AAA batteries. It can also be used with an AC
adaptor (sold separately).
