Needle-style orchestral and band tuner with 8-octave range, reference pitch playback, multiple temperaments, transpose mode, adjustable needle response, and built-in microphone

 The Korg OT-120 is a sophisticated chromatic tuner for orchestral string and wind instruments. With greater functionality than you would expect from its straightforward, vertically oriented chassis with tilt-back stand for easy viewing, the Korg OT-120 has a dual-display that comprises a virtual needle indicator and a backlit LCD screen that shows the battery life, sound output level, calibration, 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.

Fast and accurate tuning of orchestral instruments

The OT-120 features and extended tuning range from A0 to C8, and is crafted by Korg engineers to enable fast and accurate tuning of any type of band or orchestral instrument including, winds, strings, brass, or even piano for the more adventurously DIYers among us. The OT-120 also offers calibration adjustments that support concert pitch ranging from 349Hz to 499Hz in 1Hz steps.

Precise needle-style meter

With a high-precision needle-type meter the OT-120 allows you to set the speed at which the needle responds to the input. You can choose fast, medium, or slow depending on your preference. There are also two selectable tuning modes. Auto mode provides automatic pitch detection, while Manual mode lets you specify the desired note name. In Manual mode, the needle movement is displayed in a wide a range of 50 cents. In addition, the OT-120 display has LEDs located below the meter that also indicate pitch, making tuning easy in low-light environments.

Sound Back mode reference tone

The OT-120 features Korg’s proprietary Sound Back mode, which outputs a reference tone closest to the input pitch, which helps train the ear to recognize perfect pitch. Connect the optional CM-100L contact microphone to the input jack, and the OT-120’s speaker automatically produces the reference tone. The meter will also indicate the input pitch. The reference tone has a five-octave range extending from C2 (65.41 Hz) to C7 (2093 Hz). Clearly audible, the Sound Back output level is selectable in two stages.

Support for transposing instruments and historical temperaments

For tuning orchestral transposing instruments, twelve types of transposing keys are provided, including both sharps and flats. The Multi Temperament function provides eight presets that cover the most popular historical temperaments often used with period instruments.

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).

Soft case included

A durable, suede-tone soft case is included. Korg band and orchestral tuners purchased from a Korg USA authorized dealer now have a three year warranty.
