EHX Expression
Congratulations on your purchase of the EHX Expression pedal! Built to be both versatile and affordable, the EHX Expression pedal can control expression parameters on a wide array of products from various manufacturers as long as the product includes an expression jack. The TRS polarity switch provides the ability to change the connections to the TRS jack while a Reverse button and a Range knob allow the musician dial in the perfect expression sweep for their application.
CONTROLS, I/O JACKS
TRS OUT Jack – Plug a 1/4″ TRS cable into this jack. The other end of the cable should be connected to an expression input on the device you want to control. The EHX Expression pedal ships from the factory with a 1/4″ TRS cable. Under most circumstances, a standard 1/4″ TS instrument cable will not work. The cable must be TRS.
REV Button – Reverses the sweep direction of the expression pedal. The standard sweep direction is achieved when the REV button is set to its OUT position: as you move from heel to toe the expression pedal sweeps from minimum to maximum. Push the REV button to its IN position to reverse this behavior: sweep from maximum to minimum as you move from heel to toe.
TRS +/- Button – Reverses the polarity of the TRS jack for expanded compatibility with other devices. In the OUT position: the internal potentiometer’s wiper is connected to the Tip of the TRS cable and the potentiometer’s maximum setting is connected to the Ring. Press in the TRS +/- button to connect the wiper to the Ring of the TRS cable and the potentiometer’s maximum setting to the Tip. The Sleeve of the TRS cable is always connected to the potentiometer’s minimum position. For EHX pedals , set this button to the OUT position. If you find the EHX Expression does not achieve a smooth sweep over the full range of the foot pedal, try changing the TRS +/- setting.
RANGE Knob – Adjusts the minimum setting of the expression pedal. As you turn RANGE towards 0, the minimum sweep setting moves towards the fixed maximum setting. For the full range, set this knob to 10.
Included: TRS Cable
Internal Potentiometer Impedance: 10kΩ
