About the EQ modes

With Reason 2.5, the EQ modules in the Mixer were improved to get an even better sound and character. However, if you want to play back songs made in previous Reason versions, you may want to use the “old” EQ mode to ensure that the songs sound exactly the same.

On the back of the Mixer 14:2 you will find a switch for this - select “Improved EQ” for the new EQ types or “Compatible EQ” for the old-style EQ. The parameters are exactly the same in both cases.
