A 6-2 is an offensive lineup where you have 2 players acting as setters and all 6 players can be hitters. The setters line up with 2 other players between them. The setter that rotates to the the back line will move to the setting position after the ball is served. This way you have 3 hitters at the net. The setter that is rotated to the front line becomes a hitter until he/she rotates back to the back line.
