EXP OUT Jack – This jack outputs the expression value set by the
currently active knob. A TRS (tip-ring-sleeve) cable is required for this
jack. Please do not connect a TS (tip-sleeve) cable to the EXP OUT jack; it
will not work and may cause damage to your equipment.
TRS +/- Button – When this button is in the inward position, the
polarity of the EXP OUT jack is Ring-to-Wiper. When this button is in the
outward position, the polarity of EXP OUT is Tip-to-Wiper.
• This button must be set to comply with the expression polarity of
the device that is being controlled. Please check the user manual
of the device for the required expression polarity.
• For all EHX products, such as the Deluxe Big Muff Pi
®
, Deluxe
Memory Boy™ Analog Delay and Pitchfork
®
Pitch Shifter, this
toggle should be in the outward position (Tip-to-Wiper polarity).
Footswitch & LEDs – A press on the footswitch toggles the active
expression setting on EXP OUT between EXP 1 and EXP 2. If power is
applied, the LEDs below each knob light to indicate the currently active
knob.
9V Power Jack – An optional 9VDC, center-negative power supply can
be inserted to provide power to the LEDs at this jack. The current draw is
5mA. The maximum acceptable DC voltage for this power supply is
18VDC. The Cntl Knob does not take batteries.
Please note: the exact function of the Cntl Knob expression setting
depends on the device to which it is connected. Please refer to the
device’s user manual for more information on the functions assigned to
the expression input.
