Korg CA40 Chromatic Electronic Tuner

Publisher: Korg
With superior features like a large, easy-to-read, LCD needle-style display, the Korg CA-40 Chromatic Tuner is guaranteed to keep you in tune and sounding perfect!

Wide detection range
The Korg CA-40 Chromatic Tuner features a fantastically wide yet precise range that covers A0 (27.50 Hz) to C8 (4186.01Hz). You'll be able to accurately tune a variety of instruments with the renowned Korg CA-40, including wind, string, and keyboard instruments. The pitch and range are detected quickly and accurately. You can use the built-in high-sensitivity microphone to detect the pitch of an acoustic instrument without requiring any other equipment. Alternatively, you can use the separately sold CM-200 contact microphone to send the vibration of the instrument directly to the tuner, so that you can tune accurately without worrying about other sounds in the environment. An output jack (bypass) has been added, making it easy to check the tuning even while you perform.

Large, high-precision LCD meter
The Korg CA-40's display has been enlarged for superior tuning visibility. In addition to providing both the accuracy of an LCD and the easy viewing of a needle-style meter, red and green LEDs are also provided to indicate pitch deviations, making tuning smooth and easy.

Adjustable calibration
The versatile calibration function lets you adjust the pitch in 1 Hz steps over a range of 410~480 Hz in order to accommodate a variety of concert pitches, giving you the flexibility to tune accurately to any song or key. There’s also a memory backup function that preserves the Calibration setting and Sound Out settings even when you turn off the power.

Sound Out function
In addition to letting you tune visually using the meter, the Korg CA-40 Tuner provides a Sound Out function that plays a reference tone through the internal speaker, letting you tune by ear. You can adjust the reference tone in semitone steps over a range of C4 through C5 (one octave) to accommodate a variety of instruments. Since the reference tone you specify is remembered, it’s easy to sound it again whenever you need to.

Conveniently thin and compact
The CA-40 has become a classic due to its pocket size and refined design with a stand on the back that lets you place the tuner on any surface.

Fantastic battery life and auto power off function
The CA-40 is designed for long battery life, and allows approximately 85 hours of continuous use (continuous A4 input, Meter mode, zinc-carbon batteries). If, however, you do happen to forget to turn it off, the battery life will be preserved by the CA-40 turning itself off after twenty minutes of disuse.
