This Wittner quartz metronome features an adjustable dial which allows tempo range to be set between 40 and 208 beats per minute. Offers an easy to hear click beat indicator or select a flashing light beat indicator for silent practice. The MT50's speaker produces a loud "tick" sound, which is easier to hear in context than the "beep" produced by most other electronic metronomes. The MT50 also has a flashing LED beat indicator, which can be used for silent practice or along with the speaker for added visual reference.
