You can choose from three different methods of setting the tempo: pendulum step lets you specify a numeric value just as on a mechanical metronome, full step lets you specify the tempo in one-step increments, and tap tempo lets you specify the tempo by pressing a button in time with the song you're playing. You can also combine a time signature of between 0-9 beats with eight types of rhythm, supporting many types of musical practicing.
The MA-2 provides basic metronome function, but also includes a "timer mode" and a "sound out mode" that are useful for daily practicing. Use the MODE button to switch between these at a touch. A reference tone is emitted from the built-in speaker as a guide for tuning. You can select the reference tone in the one-octave range of C4-B4. The reference frequency of A4 (calibration) can be adjusted in 1 Hz increments in the range of 410 Hz to 480 Hz.
When using alkaline batteries, the unit provides approximately 400 hours of continuous operation. As the remaining battery power runs low, a battery indicator appears in the display, making it clear when the batteries need to be replaced. Even for extended practicing sessions, you can concentrate on your performance without worrying about battery life.
