Seiko Quartz Pendulum Metronome EPM5100BS School Set

A convenient set for use by schools and other organizations! With a spring-driven metronome, the balance of the weight changes, making it impossible to lengthen the baton. However, because it is a motor-driven metronome, it is possible to lengthen the baton. By attaching the included "baton extension rod," the baton's length reaches 23cm, the longest in the world! (According to SEIKO research) The included AC power supply (EPAD5000) is sold separately. You can use batteries when there is no power source, and AC power for extended practice sessions. A stereo conversion cable is included to convert your existing 6.3mm cable plug to a 3.5mm mini plug for the EPM5100. You can also connect it to an amplifier for louder sound. The main body is made in Japan, and the accessories are made in China.
