TO CONNECT & CALIBRATE AN EXPRESSION PEDAL...
Expression pedals should have a linear resistance taper and a maximum resistance in
the range of 10–100kΩ. Expression pedals must be connected using Tip-Ring-Sleeve
(“TRS”) cables.
Connect your expression pedal to one of the FM9 Pedal jacks with a TRS cable, then
follow these instructions:
1. From the Home page, open SETUP: I/O: Pedal.
2. For pedal jack 1, set Pedal 1 Setup to “PEDAL 1 (EXP/SW TIP)”
(or use Pedal 2 Setup if that’s the jack you’re connecting to)
3. Navigate down to the Calibrate function for your pedal and press ENTER.
4. Follow the on-screen instructions to perform calibration. Press HOME to nish.
Be sure to see the next page for instructions on assigning your new pedal.
If something doesn’t work, try a different pedal or cable.
FRACTAL AUDIO EV PEDALS
The Fractal Audio Systems “EV” pedals are
perfect for use with all Fractal Audio Systems
products. The EV-1 is a full-sized expression
pedal. The EV-2 is a compact version. These
pedals feature rugged cast metal casings, a
high quality 100kΩ linear potentiometer, and
built-in analog volume pedal capability.

EXPRESSION PEDALS
WHAT IS TRS? “TRS” stands for TIP-RING-SLEEVE and describes the
conguration of a 1/4" end plug or jack with three connectors. Normal guitar cables
are “TS” (Tip-Sleeve) since they lack the ring required for a third contact. Expression
pedals require TRS cables because full control voltage is transmitted to them on
one contact (the tip), while less than full voltage is returned to on another (the ring)
so the host device is able to sense and utilize the pedal position. The third contact
(sleeve) is connected to ground.
This section is for pedals connected to the local “Pedal” jacks of the FM9.
For pedals connected to an FC controller, see your FC Owner’s Manual.
