9. The tempos (BPM) of the audio sources selected by ASSIGN knobs A and B appear in the Beat Counter display.
Press the SYNC LOCK button to avoid having the displayed tempo jump rapidly. You may also press the BEAT
ASSIST button in rhythm with the music to manually enter the tempo (i.e., “tap tempo”).
10. Once each source has its respective tempo locked, the TEMPO DIFFERENCE LEDs will inform you if the tempos
match. The meter will light in the direction of the source that is faster. When the green LED lights, the tempos match.
11. Even when the tempos match, the beats may not be perfectly synced up between the sources. The TIME
OFFSET LEDs will light in the direction of the source whose audio is out of sync. When the green LED lights, the
audio is in sync.
12. To exit SYNC LOCK, press the SYNC LOCK button for mix A and B.
