CONNECTIONS
INPUT Jack – Audio input with an impedance of 2.2MΩ.
MAIN OUTPUT Jack – Main audio output with an impedance of 470Ω.
AUX OUTPUT Jack – Auxiliary audio output with an impedance of 470Ω.
EXP Jack – Expression pedal or control voltage (CV) input. The PITCH
FORK
®
+ allows for an expression pedal to be assigned to a number of
different parameters. See EXP Mode section for more details.
Expression input jack accepts a TRS expression pedal connector or a Tip-
Sleeve 0-5V control voltage input. The expression pedal should ideally use
a 10k potentiometer with linear taper. It must have the wiper connected
to TIP and toe-down connected to RING. Pedals made by some
manufacturers do not conform to this convention and would need a special
cable to swap RING and TIP. Some suggested Expression Pedals: EHX
Expression Pedal, EHX Dual Expression, M-Audio
®
EX-P, Moog
®
EP-2 &
EP-3, Roland
®
EV-5 or Boss
®
FV-500L.
EXT JACK – TRS input for connecting a generic external foot-controller
such as the EHX Triple Foot Controller or Digitech
®
FS3X. A foot-controller
has three footswitches: MODE (Tip), UP (Ring) and DOWN (Tip+Ring).
These can be used for changing modes, entering/exiting sub-menus,
loading presets, and scrolling parameter values. Saving presets cannot be
done using an external foot-controller. See the EXT section for more
details.
9V Power Jack – Power input for the EHX 9.6DC 200mA power adapter.
The PITCH FORK
®
+ uses a 2.1mm center-negative barrel plug and
requires a current rating of at least 120mA at 9VDC.
