Key Features
- 9 Programmable Memory Locations: Store and recall your favorite settings for quick access during performance.
- Vocoder Band Adjustment (8-256 bands): Customize the vocoder's sonic character, from vintage 8-band sounds to modern, highly articulate 256-band effects.
- Gender Bender for Male or Female Emphasis: Adjust vocal characteristics to sound more masculine or feminine.
- Reflex Tune for Articulate Vocal Pitch Correction: Achieve precise pitch correction, ideal for modern vocal effects.
- XLR Microphone Connector with Phantom Power: Directly connect condenser microphones without external power.
Setup and Connections
Before operating your V256 Vocoder Pedal, ensure all connections are made correctly. The pedal requires a 9V DC power supply (not included).
Power Connection
Connect a 9V DC power adapter to the 9V jack on the pedal. Use a power supply with a center-negative plug.
Audio Connections
- Microphone Input: Connect your microphone to the MIC INPUT XLR jack. The V256 provides phantom power for condenser microphones.
- Instrument Input: Connect your instrument (e.g., guitar, keyboard) to the INST INPUT 1/4" jack. This signal acts as the carrier for the vocoder effect.
- Outputs: Connect the OUTPUTS EFFECT 1/4" jack to your amplifier or mixer for the processed signal. The INST OUTPUTS 1/4" jack provides a dry output of your instrument signal.
Operating Instructions
The V256 Vocoder Pedal features intuitive controls for shaping your sound. Familiarize yourself with each knob and mode for optimal performance.
Controls Overview
- BLEND: Adjusts the mix between the dry instrument signal and the vocoded effect.
- BANDS: Controls the number of vocoder bands, from 8 (classic, lo-fi) to 256 (modern, articulate).
- TONE: Shapes the tonal character of the vocoded sound.
- GENDER BENDER: Shifts the perceived gender of the vocal sound. Turn left for more masculine, right for more feminine.
- PITCH: Adjusts the pitch of the vocoded signal, especially relevant in Reflex Tune mode.
- MIC GAIN (LO/HI Switch): Selects the input gain for the microphone. Use HI for low-output microphones or quiet vocals, LO for high-output microphones or loud vocals.
- MODE (Push Preset Knob): Selects the vocoder mode. Push to cycle through modes or load presets.
- MIC BYPASS Footswitch: Toggles the microphone signal on/off, allowing for dry vocal passages.
- PRESET Footswitch: Engages or disengages the selected preset.
Vocoder Modes
The V256 offers several distinct vocoder modes, each with unique characteristics:
- VOX-ROBO 1, 2, 3: Different variations of classic robotic vocal effects.
- SINGLE DRONE: Creates a single sustained vocal note.
- MAJOR DRONE / MINOR DRONE: Generates sustained vocal chords based on major or minor scales.
- TRANSPOSITION: Shifts the pitch of the vocoded signal up or down.
- INSTRUMENT CTRL: Allows the instrument to control the pitch of the vocoded vocal.
- REFLEX-TUNE: Provides automatic pitch correction for vocals.
Using Reflex Tune
The Reflex Tune mode offers advanced vocal pitch correction. In this mode, the PITCH knob selects the key for pitch correction. The BANDS knob controls the speed of pitch correction, from hard tuning (fast) to more natural correction (slow).
