User Manual

If you plug a standard ¼” instrument cable, with mono TS plug, into the
EXPRESSION pedal’s OUTPUT jack, the EXPRESSION pedal output will automatically
change over to Control-Voltage (CV) mode. In CV mode you can use the
EXPRESSION pedal as a CV source. The maximum range in CV mode is 0V to 5V.
Adjusting the RANGE control will move the minimum voltage from 0V up to
approximately 4.5V, the maximum voltage of 5V does not change.
ENTERING/EXITING BYPASS
Toggle between bypass and effect mode by tipping the EXPRESSION pedal forward,
in the Toe direction, past the flat position of the EXPRESSION pedal. You do not need
to tip the EXPRESSION pedal all the way forward; 25% of the total forward travel will
do it. The EXPRESSION pedal needs to return to its flat position before you can
toggle between bypass and effect mode again. Please note: while in bypass mode,
the BYPASS SETTING control on the right side of the EXPRESSION pedal adjusts the
output setting.
When the EXPRESSION pedal is in effect mode, the EHX logo in the center of the
pedal will light up. In bypass mode, the logo does not light.
POWER
Plugging into the OUTPUT jack activates power from the internal 9 Volt battery. The
input cable should be removed when the unit is not in use to avoid running down the
battery. If an AC Adapter is used, the EXPRESSION pedal will be powered up as long
as the AC Adapter is correctly plugged in.
The EXPRESSION pedal’s power jack is located on the same side as the OUTPUT jack.
A 9 Volt AC Adapter capable of delivering at least 25mA of current at 9VDC is
required to power the EXPRESSION pedal. The inner ring of the 9 Volt AC Adapter
must be negative, the outer ring positive. The optional 9V power supply from Electro-
Harmonix is 9.6DC-200BI (same as used by Boss
®
& Ibanez
®
) supplies 9.6 Volts
DC/200mA. The unit’s battery may be left in or taken out when the AC Adapter is in
use. The actual current draw of the EXPRESSION pedal is 12mA.
CHANGING THE BATTERY
1. Locate the battery door at the front of the EXPRESSION pedal, under the
Toe area of the top plate.
2. Remove the large black screw that holds the battery door to the case, most
coins or larger slotted screwdrivers can be used to remove this screw.
3. Connect your new 9V battery to the wired battery connector.
4. Insert the 9V battery into the battery holder clip on the battery door so that
the wired connector is on the same side as the hole in the battery door.
5. Place the battery door back into its window in the case of the EXPRESSION
pedal and re-install the screw.
