The TC Helicon Voice Tone C1 is a vocal processor housed in a straightforward foot pedal, offering everything from subtle pitch correction to full HardTune effects. A guitar or other instrument can be connected on the right-hand side, providing a reference signal for the vocal pitch correction. The pedal also includes a gender effect, which can transform even deep male voices into female ones. Any microphone plugged into the XLR input receives automatic 24V phantom power, allowing performers to focus entirely on their voice, while the microphone level is easily adjusted via a side-mounted gain control, keeping the interface clean and simple. Plug it in, set the levels, and let the C1 add polish to any performance.
The Voice Tone C1 features a user interface with three rotary controls, keeping operation intuitive and straightforward. The left dial selects the key for pitch correction when no signal is present from the instrument input; the middle dial adjusts the level of the correction, from subtle tuning to full HardTune; the right dial transforms a deep male voice into otherworldly feminine vocals. The footswitch engages the entire effect, while a recessed gain control on the left side allows precise adjustment of the connected microphone without risk of accidental changes. Finally, a red LED provides clear visual feedback to indicate when the pedal is active.
The Voice Tone C1 is ideal for both beginners and advanced users who want to enhance their performance with precise pitch correction, and guitarists can connect their instrument so the effect follows the notes they play. Compact and robust, it's the size of a standard foot pedal, making it easy to fit onto any stage setup, while a ground lift switch helps eliminate unwanted hum from ground loops. In addition to the footswitch, the effect can also be controlled directly from the optionally available MP-75 microphone in Mic Control mode, activated via a button on the right-hand side of the unit, and firmware updates can be easily installed through the USB port, keeping the device up to date.
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 XLR input and output on the front of the Voice Tone C1 allow the processed signal to be sent directly to a mixing console, where the overall performance volume can be controlled. Creative musicians can chain together multiple Voice Tone units in series to generate a customised sound: All they need is the separately available Singles Connect Kit, which supports up to four TC Helicon effects pedals, with the first unit controlling the overall volume. All TC Helicon vocal effects share a consistent design, featuring a black metal housing with coloured accents, ensuring a uniform, professional look when stacked together on stage.
