What Korg Say...

Large Visibility Screen

String players will love the large display screen that features a needle-style meter, with perfect pitch accuracy. This screen provides note and string name, along with red and green LEDs for pitch indication.

Compact Body

The CA-2 features a compact body profile, that can fit inside any instrument case. This credit-card sized unit is perfectly rounded, accommodating any hand shape and offering comfortable usability. A new mechanism allows the battery compartment to be easily removed for quick and easy replacement. The battery cover simply slides over the entire body, eliminating the risk misplace.

Suitable For Any Instrument

The CA-2 features a high-sensitivity built-in microphone and accommodates a variety of A0-C8, allowing speedy and high-precision tuning of wind, string, keyboard, and other instruments. For added versatility, an optional CM-200 contact microphone (sold separately) can be used to send the vibrations directly to the tuner for even more accurate tuning.

Pure Major Third & Minor Third Markings

Inaccuracies of the harmonies in a triad are particularly easy to notice when played by a brass band or orchestra, and by adjusting the pitch of a major or minor third relative to the equal-tempered interval, an excellent third can be reached. From precise intonation, the meter scale of the CA-2 includes markings to indicate pure major and minor thirds relative to a specified pitch. By tuning the instrument to these markings, players can achieve beautiful, pure harmonies when playing in group applications. If that's not enough the CA-2 also offers an adjustable calibration function of 410 to 480 Hz which can be adjusted in 1 Hz steps for accurate and flexible tuning to any song or key.

Battery Life

As well as offering quick and precise tuning, the CA-2 tuner also features a high-efficiency long-life design, offering up to 100 hours of continuous operation when used with two AAA zinc-carbon batteries, or approximately 200 hours on alkaline batteries.
