Key Features

Designed for Function
The OT-120 chromatic tuner packs precise performance and sophisticated functionality in a vertical design that's easy to hold and operate. It includes a dual-display that includes an easy-to-see needle-type indicator. Its backlit screen shows the battery life, sound output level, calibration, key and note name. The design also includes a large dial, soft-touch buttons and a rear-mounted stand that lets the unit stand by itself.

Tune Orchestral Instruments
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 OT-120 also provides a wide range of calibration to support concert pitches in a range of A440=349-499 Hz (1 Hz steps).

Precise Tuning
The OT-120 uses a high-precision needle-type metre for accurate pitch discrepancy measurement. The speed at which the needle responds to the input can be changed to fast, medium or slow to match your tuning preference.

Auto and Manual Tuning
You can choose 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 plus or minus 50 cents, letting you view the tuning discrepancy over a wide range. In addition to the needle metre, the LEDs located below the metre also indicate pitch deviation or a perfect match, making precise tuning easy even in dim locations.

Wide Range Reference Tone
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).

Transposing Keys
This unit offers supports for transposing instruments and historical temperaments. For conveniently tuning any wind instrument, twelve types of transposing keys are provided, including both sharps and flats.

Long Battery Life
The OT-120 is designed for an extended battery life of approximately 100 hours when running on two AAA batteries.
