• Hold down either “DOWN” or “UP” while you press the other button to obtain a more rapid change in the tempo value. 5. Press the BEAT Button to select the beat you like. 6. Press the START/STOP Button to start the rhythm and press it again to stop.

Try making more complicated rhythm like syncopation,  16 beat, etc., by varying the Rhythm Volume setting.

Standard Pitch 440 Hz (A4) Mode

1. Set the Power/Mode Selection Switch to “METRONOME” or “TAP”.
2.  Adjust the Rhythm Volume Slider to your taste.
3. If this Slider is set to low, there is no sound heard from the speaker.
4. Press the BEAT Button and the DOWN Button at the same time. The Display will show (440 A4) And the Standard Pitch will be output through the speaker.
5. o stop the sound, press any of the BEAT Button, the DOWN Button or UP Button.

Tempo Setting in Real Time (Tap Mode)

   • When the DB-66 is turned on, tempo is set to 120, and beat to 4.
2. By pressing the BEAT Button, Select the desired beat.
3. Tap the TAP Button in the tempo you like, as many times as necessary depending on the beat setting in the step 2.

• When 0 or 1 beat is selected in the step 2, hitting the TAP Button twice is enough. But when 2, 3, 4, 5 or 6 beat is selected, hit the TAP Button as many times as the number of selected beat, and next tapping will cause the Display to show the average tempo of the tapping.

At this stage if you return the Power/Mode Selection Switch to “METRONOME”, the DB-66 is ready to work as a metronome in the last temp setting.

Error Indications in Tap Mode

When the tempo you set is faster than 250 the Display will show (High)

When the tempo you set is as slow as 30 to 34, the Display will show (Low)

When the tempo you set is slower than 30, the tempo setting just before that will remain. Therefore, if you stop the real time tempo setting in the middle and start again later, the DB-66 will work in this last tempo.

Turning the DB-66 off sill erase the tempo setting
