EXPRESSION
EXPRESSION / CV PEDAL
Congratulations on your purchase of the Electro-Harmonix EXPRESSION pedal from
our ground-breaking NEXT STEP series! The EXPRESSION pedal has no moving
parts: it does not use a potentiometer, optics or magnetism to sweep expression
enabled controls on other devices. The result is a responsive expression pedal that
allows precise control over your expression or control-voltage capable effects and
instruments.
GETTING STARTED
The EHX EXPRESSION pedal ships from the factory with a TRS cable. The TRS cable
is necessary when connecting the EXPRESSION pedal to a device with an expression
control input. Plug one end of the included ¼” TRS cable into the OUTPUT jack of the
EXPRESSION pedal; connect the other end of the TRS cable into an effect or
instrument with an expression input. Within seconds the EHX logo in the center of the
pedal will light. Your EXPRESSION pedal is now ready for use. Please note: as long
as a plug is inserted into the OUTPUT jack, a drain is placed on the 9V battery inside
the EXPRESSION pedal. We recommend you unplug the OUTPUT jack when the
EXPRESSION pedal is not in use to extend battery life.
CALIBRATION
To ensure the EXPRESSION pedal responds to its full sweep range, it may be
necessary to calibrate the sweep of the EXPRESSION pedal when it is used on a
different surface since its last use. It is particularly important to calibrate if the
EXPRESSION pedal is used on a slanted surface. We also recommend calibrating the
EXPRESSION pedal during your first use of the pedal.
CALIBRATION PROCEDURE
1. Place the pedal on the surface where it will be used.
2. Ensure the EXPRESSION pedal is sitting flat on the surface then press and
release the CALIBRATE button once; the EHX logo begins to blink indicating
the Toe position has been saved.
3. While the EHX logo continues to blink, rock the pedal all the way back to the
extreme Heel position and hold it there.
4. Press and release the CALIBRATE button once more.
5. The EHX logo will stop blinking to indicate that the Heel position has been
saved. The calibration procedure is complete.
If you accidentally press the CALIBRATE button and the EHX logo blinks, do not press
CALIBRATE again. After approximately 7 seconds, the EXPRESSION pedal will stop
blinking and ignore the button press.
RANGE Control
The RANGE dial located on the right side of the EXPRESSION pedal controls the Heel
setting of the pedal’s sweep (or Toe setting with REVERSE engaged). As the numbers
on the dial increase, the expression sweep range increases. Minimum range occurs
when the control is set to 0; maximum range is achieved at a setting of 10. Please
note: When the REVERSE button is out, the RANGE control only restricts the Heel
setting, not the Toe. If REVERSE is pushed in, the RANGE control only restricts the
Toe setting, not the Heel.
BYPASS SETTING Control
This dial controls the EXPRESSION pedal’s output setting while in bypass mode. A
setting of 0 for BYPASS SETTING is equivalent to the Heel position. A setting of 10 on
the dial is equivalent to the Toe position. Setting the dial anywhere in between will
yield an intermediate bypass setting. Please note: the RANGE and REVERSE controls
have no affect on the BYPASS SETTING control. BYPASS SETTING always sweeps
through the entire EXPRESSION pedal’s range.
REVERSE Button
The REVERSE button reverses the direction of the EXPRESSION pedal’s output as it is
swept from Heel to Toe. This button has two positions: out and in. Set to out,
REVERSE is disengaged and the EXPRESSION pedal’s output increases as you move
the pedal from Heel to Toe. In most cases, this is the equivalent of turning a knob in
the clockwise direction or pushing a slider control upward. Pushing the REVERSE
button to the in position engages the Reverse function. When set to the in position,
the output of the EXPRESSION pedal decreases as you move the pedal from Heel to
Toe. This is the equivalent of turning a knob counter-clockwise or pushing a slider
downward. Please note: the REVERSE button does not change the polarity of the
TRS OUTPUT jack, it only changes the direction of the EXPRESSION pedal’s sweep.
OUTPUT Jack: TRS = EXP, TS = CV
The type of cable inserted into the OUTPUT jack determines the output state of the
EXPRESSION pedal. When a TRS cable (the cable supplied with the EHX EXPRESSION
pedal) is plugged into the OUTPUT jack, the pedal works as a standard expression
pedal with the following connections: TIP = potentiometer wiper or output signal,
RING = Toe position and SLEEVE = Heel position. This is the standard polarity for
the TRS plug of an expression pedal that many in the industry follow including all
EHX products as well as Boss
®
/Roland
®
, Moog
®
, Nord
®
etc. The REVERSE button
does not change the TRS plug polarity, it only changes the direction of the output
sweep.
