Quick Start Guide
The TC Helicon VoiceTone C1 is a 1-button stompbox designed for flexible pitch correction. This guide provides the necessary information to set up and operate the device effectively.
Device Controls
The VoiceTone C1 features several controls for adjusting your vocal sound:
- Key Selector: Selects a major key for pitch correction. The CH setting is either Chromatic (no instrument) or Chords (instrument connected).
- Mic Input Level Control: Adjusts the gain of the microphone input.
- Ground Lift: Press the button inward if you experience buzz or hum.
- Instrument Thru: Sends a copy of the instrument input signal to an amp or PA.
- Effect On/Off Footswitch: Toggles the pitch correction effect.
- Mic Control: Use with the optional MP-75 microphone (button in = on).
- Gender: Adjusts your vocal biology between male and female.
- Off/Hard: Adjusts the pitch correction attack from natural to robotic.
Setup and Connections
To set up your VoiceTone C1, follow these steps:
- Power: Connect the included 12 V / >= 400 mA power supply to the Power input.
- Microphone: Connect your microphone to the Mic input.
- Instrument: Connect your instrument to the Guide Instrument Input (optional, for chord-based pitch correction).
- Output: Connect the Out to a mixer or powered speaker.
- USB: Use the USB port for firmware updates using the included mini-USB cable.
Operation
The VoiceTone C1 provides real-time pitch correction. Use the Key Selector to set the desired key. If you are using an instrument, the CH setting allows the pedal to follow the chords you play. Use the Gender knob to shift the vocal character and the Off/Hard knob to determine how aggressively the pitch correction is applied, ranging from subtle natural correction to a hard-tuned robotic effect.
