This tuner is ideal for tuning even low-register notes containing numerous overtones that are often difficult to tune. A high-sensitivity mic is built-in, allowing easy and accurate tuning of acoustic instruments such as ukuleles. A separately sold CM-100 contact mic 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-1 is small, thin, and light, don’t let the pocket-sized body fool you. The CA-1 can accurately
tune 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 a 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.
Sound Out -- Internal Speaker Provides a Reference Pitch
In addition to visual tuning via meter, the GA-1/CA-1 can play reference pitches from the internal speaker (Sound Out) for
tuning by ear. Each press of the Sound switch will cycle the output sound notes. On the GA-1, 7B->6E->5A->4D->3G->2B->1E in Guitar mode, or LB->4E->3A->2D->1G->HC in Bass mode. On the CA-1, A4-Bb4 notes commonly used for tuning wind instruments. Or 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.
Adjustable Calibration (CA-1)
The Calibration function (410-480 Hz) 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
Auto Power Off Function
If you leave the unit powered-on for 20 minutes without performing any operation, the Auto Power Off function will turn the
power off automatically, avoiding unnecessary battery consumption.
Approximately 100 hours of continuous use
