The TC-Helicon VoiceTone H1 is a compact and powerful vocal harmony stompbox that adds rich, varied, and realistic-sounding backing voices to the lead vocal with minimal effort. Designed for singers, solo performers, and acoustic musicians, it generates up to two harmony voices centred on the input, delivering smooth, natural-sounding harmonies that convincingly enhance vocal performances. The pedal offers multiple styles of harmony, allowing users to select intervals above or below the lead. Guitarists can take advantage of automatic key detection, which follows the instrument and generates harmonies in real-time, while instrument-free singers can set the key manually. Housed in a rugged metal chassis, the VoiceTone H1 is built for both intensive stage and studio use, providing a great performance in any setting.
With just three rotary controls and a footswitch, the TC-Helicon VoiceTone H1 is designed for simplicity and efficiency. The Key knob sets the central key for harmonisation when no instrument is connected, while the Voice knob determines whether the harmonies are above or below the lead vocal, or a combination of both. The Mix knob blends the harmonised signal with the dry vocal, allowing precise balance between the "backing" and lead vocals. The pedal's high-resolution LED provides clear visual feedback on activity status. Additionally, a ground lift switch on the side helps eliminate unwanted hum in certain setups. The footswitch engages or bypasses the harmonies instantly, ensuring seamless transitions during performances.
Built for stage use, the VoiceTone H1 features balanced XLR input and output connectors to easily integrate into any setup. The onboard 24V phantom power supports dynamic and live condenser microphones, ensuring compatibility with a wide range of vocal mics (certain studio condenser microphones, however, require more power and will not function with 24V, so user discretion is advised). Singers using the TC-Helicon MP-75 or Sennheiser e835 FX microphones can control the pedal remotely using the built-in Mic Control function, allowing hands-free operation. The compact, pedalboard-friendly design makes the VoiceTone H1 ideal for solo performers looking to add professional-grade harmonies to their set without requiring external processing or a second vocalist.
TC-Helicon was founded in 2000 as a subsidiary of TC Electronic in cooperation with IVL Technologies Ltd. and has since specialised in voice recording technology. TC-Helicon focuses primarily on portable audio interfaces. The product range also includes various signal processors designed for the voice, in the form of effect pedals or compact devices with microphone stand mounts. Since 2015, TC Helicon has belonged to Music Tribe, the holding company of Behringer, which has brought brands such as Midas and Klark Teknik under one roof.
The VoiceTone H1 can be used as a standalone pedal or daisy-chained with other TC-Helicon VoiceTone effects to create a customised vocal processing chain. The XLR output connects directly to a mixing console, PA system, or audio interface, providing a clean and clear signal at all times. The pedal's USB port allows firmware updates, keeping it up to date with the latest features and improvements. Compact yet powerful, the VoiceTone H1 is an essential tool for vocalists seeking rich, natural harmonies with intuitive control and professional-grade sound.
