TC Helicon VoiceTone H1 Harmony Effect Pedal

SKU CH-N461-FFNM7

Adds up to two natural-sounding harmony voices with eight styles, auto-detecting key from guitar input and chaining with other VoiceTone pedals

  • Two natural harmony voices with eight style choices
  • Guitar input auto-detects song key and scale instantly
  • Rugged die-cast metal chassis with rubberised base stays put
  • Mic Control enables remote on/off with MP-75 microphone
  • 24 V phantom power always on for condenser microphones

Purpose and User

The TC Helicon VoiceTone H1 is a floor pedal that adds up to two harmony voices above or below a lead vocal. It suits singers who want instant harmonies without menu diving, whether performing solo with a guitar or running a dedicated vocal chain. Guitarists benefit from automatic key detection through the instrument input, while other vocalists can set the key manually.

Bundled Extras and Control

A 12 V 0.4 A power supply is included so the unit works straight out of the box. A USB port allows firmware updates and parameter editing from a computer. Remote on/off switching is possible when paired with the optional TC-Helicon MP-75 microphone, letting the singer toggle harmonies without bending down. Chaining multiple VoiceTone Singles expands the effects palette without extra cabling complexity.

Interface Limits

The XLR microphone input accepts levels from -42 dBu to +1 dBu with 24 V phantom power always active, so dynamic and condenser mics are both supported. Guitar input impedance is 1 MΩ and handles -7 dBu to +17 dBu. Balanced outputs present 200 Ω impedance and deliver +1 dBu full scale with greater than 104 dB dynamic range from 20 Hz to 20 kHz. Power draw is 5.6 W.

Questions about this item

Does the XLR microphone input need any periodic servicing or phantom-power component replacement?

The XLR input provides 24 V phantom power that is always on, and the preamp achieves an EIN of -126 dBu at 150 Ω; no user-serviceable parts are inside the sealed die-cast chassis.

What limits continuous operation — thermal shutdown, DSP headroom or the 5.6 W power budget?

The unit draws 5.6 W from the supplied 12 V 0.4 A adapter, runs with a rubberised base for passive cooling, and specifies a dynamic range above 104 dB with no thermal-limit mention.

How much heat or fan noise appears when the pedal stays on all day?

There is no fan; the metal chassis and rubberised base dissipate the 5.6 W silently, and the balanced outputs hold +0/-0.3 dB from 20 Hz to 20 kHz during extended use.
