> - I suspect what is happening, is that you are attempting to change the tempo of the **Slave Deck** instead of the **Master Deck**.
> - In this situation, Sync will turn OFF because the system assumes you want a different tempo for your incoming song.
> - For example, if are playing on Deck 1 with the Crossfader to the Left and the Channel Fader open, this will be considered the Master Deck because this is the one with audio going to the sound system.
> - If Sync is ON for both decks, but you try to use the Tempo Fader for Deck 2 (which is the slave), Sync will turn OFF. Instead trying using the Tempo Fader of Deck 1 (which is the master).
> - Just remember, the easiest way to determine which deck is the master is by which one the audience can hear.
> - Please try this and let me know if that works.
