Using the
Expression Pedal Feature
Use a TRS (Tip-Ring-Sleeve) 1/4" cable to connect the Alesis F2's
EXPRESSION IN/OUT jack to the expression jack of your Alesis
Fusion, Alesis Spitfire, or other product.
Different products use one of two different wiring standards. Flip the
INPUT SELECT switch to either the left or right position for
compatibility with your device. Feel free to experiment with the switch
to see which setting works best: you won't do any damage to your gear
by flipping the switch one way or the other.
Calibrating the
Expression Pedal
When shipped, the Alesis F2 is set to travel smoothly from the bottom
of its range to the top of its range. However, some devices will ignore
the signal sent out of the expression jack when the pedal approaches the
top of its range. To compensate for this, you can set the F2 to resist
your foot at some point before the F2 reaches the top of its range.
Bottom panel
Locate the recessed, Phillips-head screw on the bottom of the F2.
This is located near the center of the rear panel and just a bit to the
left. (See the drawing at right.) Use a Phillips head screwdriver to
adjust how far the pedal will travel before it offers resistance.
Turn the screw clockwise to make the resistance take effect earlier
in the pedal's range of motion.
