Stylish design that’s reminiscent of a mechanical metronome
The KDM-3’s design is similar to that of an acoustic mechanical metronome, except much smaller. It will fit nicely on a tabletop, on your piano, or in any practicing environment. Featuring a newly designed sealed speaker enclosure, it delivers powerful volume that exceeds its compact size. The lineup gives you a choice of two colors: sophisticated black or pure white.
Eight metronome sounds, including a mechanical metronome sound
The design is not the only way in which this unit is reminiscent of a mechanical metronome. The KDM-3 now provides the sound of an acoustic mechanical metronome. You can also choose alternative sounds to suit your performance or instrument, including cowbell, rimshot, or voice. All of these sounds deliver a clear tone that is easy to hear and will not be obscured even by high-volume instruments.
19 beat patterns support songs of any genre
In addition to 0-9 beats per measure with your choice of duplets, triplets, triplets omitting the middle note, quadruplets, and quadruplets omitting the middle notes, we've provided variations such as son clave and rumba clave, for a total of 19 built-in beat patterns. The tempo can be freely specified in the range of 30 to 252 beats/minute. From classic to pop, jazz, and Latin, this unit covers your needs in a wide range of genres.
Easy one-touch operation, and an easily-readable display
The START/STOP button located on top of the unit blinks in two colors, red and green, giving you a clear visual indication of the tempo. You can even start practicing with the volume set to zero. The TEMPO/CALIB dial on the top panel provides easy access to the numerical setting that you want. The content of the setting is visible at a glance in the large display.
Choose from three types of tempo settings to suit your needs
You can set the tempo in any of three ways: Pendulum Step lets you increase or decrease the tempo using the same increments as the numerical values of a standard mechanical metronome, Full Step lets you specify the tempo in one-step increments over the full range of 30 to 252, and Tap Tempo lets you set the tempo by pressing the TAP button at the desired interval.
Sound Out mode lets you tune while listening to a reference tone
Sound Out mode produces a reference tone from the built-in speaker or through connected headphones, allowing you to tune by ear. It can generate 12 reference tones in the range from C4 (261.63 Hz) to B4 (493.88 Hz). The calibration of the A4 pitch can also be adjusted over a wide range of 410 Hz–480 Hz.
Timer mode is convenient for practicing the basics
Timer mode is a function that operates the metronome for a specified length of time and then automatically stops. It’s a great convenience for warming-up or when practicing the basics.
Memory Backup function and Auto Power-Off function
Even when the power is turned off, the Memory Backup function preserves the specified tempo, beat, calibration, and reference tone. (These settings are initialized when the batteries are replaced.) The Auto Power-Off function automatically turns the power off when 20 minutes have elapsed with the metronome stopped.
Long-life design ensures worry-free performance even during extended practice sessions
The KDM-3 allows approximately 120 hours of operation when used at 120 beats/minute at maximum volume. Even if you're practicing daily, you won’t need to worry about the remaining battery life.
