Expression Pedals - Fractal FM3 Owner's Manual

1 INTRODUCTION

EXPRESSION PEDALS

This section is for pedals connected to the local "Pedal" jacks of the FM3.
For pedals connected to an FC Series controller, see your FC Owner's Manual.
Each of the two Pedal jacks of the FM3 support one expression pedal (or 1 to 2 switches).
TO CONNECT & CALIBRATE AN EXPRESSION PEDAL . . .
EXPRESION
Expression pedals should have a linear resistance taper and must have a maximum
PEDAL
resistance in the range of 10–100kΩ. Expression pedals must be used with Tip-Ring-
Sleeve (TRS) cables.
Connect your expression pedal to one of the FM3 Pedal jacks with a TRS cable, then
follow these instructions:

"TRS" stands for TIP-RING-SLEEVE and describes the
WHAT IS TRS?
configuration 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.
