KORG KDM-3-BK - Digital Metronome with Classic Design, 8 Sounds and 19 Patterns (Black)

The KORG KDM-3-BK modernizes the look of the traditional mechanical metronome with digital features built for serious practice: eight sounds (including an English voice and the iconic mechanical “click”), 19 rhythm patterns , a Sound Out mode for outputting a reference tone, and a Timer mode for structuring sessions. Its tempo control offers three methods — pendulum , whole step , and tap tempo —covering 30 to 252 bpm with ±0.2% accuracy . Reference pitch ranges from C4–B4 with A4 calibration = 410–480 Hz (1 Hz) and ±1 cent accuracy , useful for quick tuning checks. It features a memory backup (retains settings when powered off) and a 20-minute auto-off function , plus a headphone output (3.5 mm stereo) and a 36 mm dynamic speaker for classroom use or silent practice. It runs on 4 AAA batteries and has a battery life of approximately 120 hours (depending on usage conditions). Compact dimensions of 60 × 73 × 113 mm and a weight of 167 g , it comes in a sleek black finish.
