Large, Easy-to-Read Display

The CA-50 features an enhanced LCD display with a needle-style meter and enlarged note name indication, making tuning easier and more intuitive than ever. The improved visibility allows musicians to quickly identify pitch deviations and make precise adjustments, even in rehearsal rooms, classrooms, and stage environments.

The clear display is particularly beneficial for beginners and young musicians who are developing their tuning skills and learning to recognize pitch accurately.

The Korg CA-50 offers an extensive detection range from A0 (27.5Hz) to C8 (4186Hz), allowing it to accommodate an exceptionally broad range of instruments. From piccolo and flute to tuba, and from violin to double bass, the tuner provides reliable performance across virtually every orchestral and band instrument.

The built-in high-sensitivity microphone accurately detects pitches without requiring additional accessories, while compatibility with optional contact microphones offers even greater flexibility in noisy environments.

High-Precision Tuning Performance

Designed for accurate and dependable tuning, the CA-50 delivers a detection accuracy of ±1 cent, enabling musicians to achieve precise intonation with confidence. The meter also includes indicators for pure major and minor third intervals, making it especially useful for ensemble playing, orchestral rehearsals, choir practice, and a cappella performances where harmonic accuracy is essential.

Calibration Function for Flexible Tuning

The built-in calibration function allows adjustment of concert pitch from A4 = 410Hz to 480Hz in 1Hz increments. This flexibility enables musicians to match different tuning standards, accommodate historical performance requirements, and adapt to specific ensemble or repertoire needs.

Sound Out Mode for Ear Training

The CA-50 features a convenient Sound Out mode that produces a reference tone through the built-in speaker. Users can listen to pitches ranging from C4 to C5 and tune by ear, making the tuner an excellent tool for developing pitch recognition and improving intonation skills.

By combining visual meter indications with audible reference tones, musicians can strengthen both their tuning accuracy and ear training abilities.

With its slim and lightweight construction, the Korg CA-50 easily fits into an instrument case, music bag, or pocket. The integrated folding stand provides added stability when placed on a music stand, while the improved chassis design minimizes the risk of the tuner slipping or tipping during practice and performance sessions.

A battery indicator alerts users when replacement batteries are needed, ensuring uninterrupted operation.
