Electro-Harmonix Pitch Fork Polyphonic Pitch Shift Pedal User Manual

Comprehensive guide for setup, operation, and maintenance of your Electro-Harmonix Pitch Fork pedal.

1. 서론

The Electro-Harmonix Pitch Fork is a polyphonic pitch shift pedal designed to transpose an instrument's pitch over a +/- three-octave range. It offers three distinct modes for pitch transposition: up, down, or both simultaneously. The pedal allows for precise control over the pitch shift amount, which can be set to a fixed interval or continuously varied using an external expression pedal or control voltage. Its intuitive controls ensure ease of use for musicians seeking to expand their sonic capabilities.

2. 특징

  • Three shift modes: up, down, or dual.
  • 11-position Shift knob for selecting transposition intervals.
  • EXP input for controlling pitch shift or glissando via an optional expression pedal.
  • Latch and Momentary modes to define footswitch and EXP input behavior.
  • Blend knob to control the mix of dry and effected signals.
  • Compact and durable metal chassis.
  • Includes EHX 9.6DC-200 mA power supply and can also run on a 9 Volt battery.

3. 제어 및 연결

Familiarize yourself with the Pitch Fork's controls and connections:

  • 블렌드 노브: Controls the mix between your dry (unaffected) instrument signal and the wet (effected) pitch-shifted signal. Turn clockwise for more effect, counter-clockwise for more dry signal.
  • 변속 레버: An 11-position rotary switch that selects the maximum transposition interval. Settings range from D (Detune, 17 cents) through Minor 2nd, Major 2nd, Major 3rd, Perfect 4th, Perfect 5th, Major 6th, Minor 7th, 1 Octave, 2 Octaves, and 3 Octaves.
  • 듀얼 토글 스위치: A three-position toggle switch that determines the direction of the pitch shift.
    • 쪽으로: Shifts the pitch upwards.
    • 내려가는: Shifts the pitch downwards.
    • 듀얼: Outputs two pitch-shifted signals simultaneously. One follows the SHIFT knob as if in the UP position, while the other creates a harmony. Dual Mode settings include M3 up + P5 up, P5 up + 1 Oct down, 1 Oct up + 1 Oct down, and other combinations.
  • LATCH/MOMENTARY Switch: Affects the behavior of the footswitch and the EXP input.
    • 래치 모드: The footswitch toggles the effect between on and off with each press. The EXP input continuously varies pitch.
    • 순간 모드: The effect is active only while the footswitch is depressed. Releasing the footswitch bypasses the effect. In this mode, the EXP input controls the glissando rate for the footswitch.
  • 풋스위치: Engages or bypasses the effect, depending on the LATCH/MOMENTARY mode.
  • 입력 잭: 1/4인치 계측기 입력 단자.
  • 출력 잭: 1/4-inch effect output.
  • EXP 잭: Connects to an optional expression pedal (e.g., EHX Expression Pedal) or control voltage source for dynamic control over pitch or glissando.
  • 9V Power Jack: Connects to the included EHX 9.6DC-200 mA power supply.

4. 설정

4.1 페달에 전원 공급하기

The Pitch Fork can be powered by either a 9V battery or the included EHX 9.6DC-200 mA power supply.

  • 배터리 설치: To install a 9V battery, remove the four screws on the bottom of the unit. Take off the bottom plate and connect the 9V battery to the clip. Replace the bottom plate and screws.
  • 전원 공급 장치: Connect the output plug of the EHX 9.6DC-200 mA power supply into the 9V power jack on the top of the Pitch Fork. The pedal requires 9V DC at 50mA with a center-negative plug.

4.2 Connecting to Your Rig

  1. Connect your instrument (e.g., guitar, bass) to the 입력 페달 오른쪽 측면에 있는 잭에 표준 1/4인치 악기 케이블을 사용하여 연결합니다.
  2. 연결하다 산출 페달 왼쪽의 잭을 당신의 것에 연결하세요 amplifier or the next effect pedal in your signal chain using another 1/4-inch instrument cable.
  3. If using an expression pedal, connect it to the 경험치 잭.

5. 사용 설명서

5.1 Basic Pitch Shifting

  1. Ensure the pedal is powered and connected as described in the Setup section.
  2. 설정하다 LATCH/MOMENTARY 로 전환하다 걸쇠 mode for standard on/off operation.
  3. Select your desired pitch shift direction using the 듀얼 toggle switch (UP, DOWN, or DUAL).
  4. 회전하다 옮기다 knob to choose the desired transposition interval (e.g., 1 Octave, Perfect 5th).
  5. 조정하다 혼합하다 knob to mix the dry and effected signals to your preference.
  6. Press the footswitch to engage the pitch shift effect.

5.2 Using an Expression Pedal (EXP Input)

An expression pedal connected to the EXP jack offers enhanced control:

  • In LATCH Mode: The expression pedal continuously varies the pitch. The heel position corresponds to the original pitch (unity), and the toe position corresponds to the interval set by the SHIFT knob. This allows for smooth pitch bends or "whammy" effects.
  • In MOMENTARY Mode: The expression pedal controls the glissando rate. When the footswitch is pressed, the Pitch Fork jumps from bypass to the interval set by the SHIFT knob. The amount of time it takes to reach that new note is the glissando rate. When the footswitch is released, the pitch returns to unity at the same rate. The glissando time can vary between 4 milliseconds (heel position) to two seconds (toe position) depending on the expression pedal's position.

6. 유지관리

To ensure the longevity and optimal performance of your Pitch Fork pedal, follow these maintenance guidelines:

  • 청소: 페달 외부를 닦을 때는 부드럽고 마른 천을 사용하십시오. 연마성 세척제나 용제는 마감재나 내부 부품을 손상시킬 수 있으므로 사용하지 마십시오.
  • 저장: 페달을 사용하지 않을 때는 직사광선과 극한의 온도를 피해 시원하고 건조한 곳에 보관하세요.
  • 전원 공급 장치: Always use the included EHX 9.6DC-200 mA power supply or a compatible 9V DC center-negative power supply. Using an incorrect power supply can damage the unit and void the warranty.
  • 배터리 교체: If using battery power, replace the 9V battery when the effect LED dims or the pedal's performance degrades. Remove the battery if the pedal will not be used for an extended period to prevent leakage.

7. 문제 해결

If you encounter issues with your Pitch Fork pedal, consult the following common troubleshooting steps:

  • 소리 없음:
    • 모든 케이블 연결 상태(기기와 입력 단자, 출력 단자)를 확인하십시오. amp리퍼).
    • Ensure the power supply is correctly connected and functioning, or that the 9V battery is fresh and properly installed.
    • 귀하의 악기와 amplifier가 올바르게 작동하고 있습니다.
    • If using an expression pedal, try disconnecting it to rule out any issues with the expression pedal itself.
  • Unexpected Pitch Shifting/Tracking Issues:
    • 확인하십시오 옮기다 knob is set to the desired interval.
    • 확인하세요 듀얼 toggle switch position.
    • 확인하다 혼합하다 knob setting; if set fully wet, you might not hear your dry signal for reference.
    • 확인하십시오 LATCH/MOMENTARY switch is in the intended position. Momentary mode will only engage the effect while the footswitch is held down.
    • If using an expression pedal, ensure it is calibrated correctly and functioning as expected.
  • 소음 또는 험:
    • 다른 콘센트나 전원 공급 장치를 사용해 보세요.
    • 모든 케이블이 양호한 상태이고 적절하게 차폐되어 있는지 확인하십시오.
    • 페달을 간섭을 일으킬 수 있는 다른 전자 기기에서 멀리 떨어뜨려 놓으십시오.
