Wide Range of Pitch Detection
This compact chromatic tuner supports a broad range of C1 (32.70 Hz)-C8 (4186.01 Hz), allowing speedy and high-precision tuning of wind, string, keyboard, and other instruments. This hand held tuner is ideal for tuning even low-register notes containing numerous overtones that are often difficult to tune. A high-sensitivity microphone is built-in to this chromatic tuner, allowing easy and accurate tuning of acoustic instruments such as ukuleles. A separately sold CM-100 contact microphone can also be used to send the vibrations directly to the tuner for even more accurate tuning.
Ultra-compact body with a "Tilt Slit"
Although the CA-30 is small, thin, and light, don't let its pocket-sized body fool you. The CA-30 chromatic tuner packs the functionality needed for tuning a wide range of instruments. From studio to stage, tuning is easy and convenient. The back of the unit includes a unique arc-shaped "tilt slit" that lets you insert a plastic card for use as a handy stand.
High-precision LCD Meter
The meter section uses an LCD needle, combining the accuracy of an LCD with the easy visibility of a needle, and providing a stable display. Additional visual feedback is provided by LEDs that indicate pitch deviation.
In addition to visual tuning via meter, the Korg CA-30 can play reference pitches from its internal speaker (Sound Out) for tuning by ear. Each press of the Sound switch will cycle through the A4-Bb4 notes, commonly used for tuning wind instruments. Alternatively, you can hold down the Sound switch to change the cycle to the semitone intervals from C4 through C5 (one octave), allowing reference pitches for any instrument to be sounded quickly.
The Calibration function (410-480 Hz) of this chromatic tuner supports a wide range of standard pitches, and can be adjusted in 1 Hz steps for accurate and flexible tuning to any song or key. Thanks to the Memory Backup function, the Calibration and reference pitch are remembered even when the power is turned off. (However, these settings will be initialized when the batteries are replaced.)
Auto Power Off Function
The power will turn off automatically if the unit is left powered-on for 20 minutes without performing any operation, avoiding unnecessary battery consumption.
Approximately 100 hours of Continuous Use Low-power consumption design allows an amazing 100 hours (approximate) of continuous battery life (A4 continuous input, meter mode, zinc-carbon batteries).
Three Year Warranty
Korg tuners and metronomes purchased from a Korg USA authorized dealer now have a three year warranty.
