Consists of a credit-card-size LCD display digital metronome (30 to 250 bpm) with a built-in tweeter tone and an audio amplifier for a much louder tone (200mw). The digital unit uses a long-life lithium battery and is adjustable in 1 bpm increments with crystal controlled accuracy. The amplifier uses a 9 volt battery or optional AC adapter. You can input radios, personal audio players, etc. Sizes: 2x3.25x3/8" & 2.6x3.5x1.5".
Pocket Metronome with output jack. Same metronome as above, less the audio amp. The "tiny-phone" output jack will allow you to patch into your own P.A.
Features an easy-to-use dial to quickly set any pace from 40 to 208 beats per minute. Select both the LED light and sound or light only mode. A built-in stand and personal earphone are included.
