3.2 Audio Connections
The pedals offer various input and output options:
- MIC Input: Connect your microphone to the XLR input. The pedal supports 48V phantom power for condenser microphones.
- LINE IN: Connect line-level audio sources here.

4. Operating Instructions
4.1 FV01 Corrector Pedal Operation
The FV01 is designed for pitch correction and vocal effects. It features controls for Delay, Reverb, and Correction.
- TONE LED: This LED indicates the current EQ mode (WARM, BRIGHT, NORMAL). Press the footswitch to cycle through these modes.
- REVERB Knob (RM/HL/PL): Adjusts the reverb type and level. RM (Room), HL (Hall), PL (Plate).
- DELAY Knob (TP/DG/SL): Controls the delay type and level. TP (Tape), DG (Digital), SL (Slapback).
- CORRECTION Knob (0-100): Adjusts the intensity of pitch correction. Higher values apply more correction.
4.1.1 Output Modes (FV01)
The FV01 supports two distinct output modes:
- Individual Output Mode: Vocal signal is routed through the XLR OUT, and guitar signal through GUITAR OUT.
- Mixed Output Mode: Both vocal and guitar signals are mixed and routed through the XLR OUT.
To switch between modes, press and hold the footswitch while powering on the pedal:
- Blinking Blue LED: Individual Output Mode.
- Blinking Red LED: Mixed Output Mode.

- MODE Knob (1-6): Selects different vocal character effects.
- Male
- Female
- Baby
- Robot 1
- Robot 2
- Robot 3
- REVERB Knob (RM/HL/PL): Adjusts the reverb type and level. RM (Room), HL (Hall), PL (Plate).
- MIX Knob (0-100): Controls the blend between the dry vocal signal and the wet (effected) signal.
- TONE LED: Similar to FV01, indicates EQ mode (WARM, BRIGHT, NORMAL).

5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the pedal's surface. Do not use abrasive cleaners or solvents.
- Storage: Store the pedal in a cool, dry place away from direct sunlight and extreme temperatures.
- Power: Always disconnect the power supply when the pedal is not in use for extended periods.
- Handling: Avoid dropping or subjecting the pedal to strong impacts, as this can damage internal components.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output. | Incorrect cable connections, power issue, pedal bypassed. | Check all audio cables and power supply. Ensure the pedal is engaged (not bypassed). |
| Distorted or noisy sound. | Input level too high, faulty cable, ground loop. | Reduce input gain. Try different cables. Use the GND LIFT switch if available (FV03). |
| Pitch correction not working (FV01). | Correction knob set too low, incorrect input signal. | Increase the CORRECTION knob setting. Ensure a clear vocal input. |
| Character effects not changing (FV03). | MODE knob not rotated. | Rotate the MODE knob to select different character effects. |
