Description

Transform your live performances with the TC Helicon Duplicator - Vocal Effects Stompbox, an intuitive pedal designed to elevate your vocal presence with minimal effort. This compact yet powerful unit brings studio-grade vocal effects to any stage, courtesy of its high-quality preamp and easy-to-use controls. Whether you're a seasoned performer or just starting out, the Duplicator offers a seamless way to enhance your sound with its intelligent features.

At the heart of the Duplicator is TC Helicon's renowned Adaptive Tone technology, which automatically adjusts your EQ, compression, de-essing, and gating to ensure your vocals are consistently polished and professional. With three distinct doubling modes—Tight, Loose, and Octave—you can add depth and richness to your voice, creating a fuller sound that resonates with any audience. The built-in reverb, sourced from TC-Helicon's flagship VoiceLive series, envelops your vocals in lush, ambient tones, transforming any venue into a virtual concert hall.

For those moments when pitch perfection is a must, the Duplicator's pitch correction feature subtly corrects any off notes in real-time, keeping your performance on point without drawing attention to the correction itself. Plus, with the addition of a Talk mode, you can effortlessly switch between singing and speaking, maintaining clarity and presence in both.

Key Features:

  • High-quality mic preamp with low noise
  • Adaptive Tone for automatic EQ, compression, de-essing, and gating
  • Three doubling effects: Tight, Loose, and Octave
  • Studio-grade reverb for a range of ambient effects
  • Auto-chromatic pitch correction
  • Talk mode for optimized spoken-word performance
  • Rugged, road-ready construction
  • Compatible with TC Helicon MP-75 and Sennheiser e835 FX microphones for remote control

Very Useful for filling up smaller gig spaces

Great addition for certain aspects of songs requiring just a touch more than reverb on a vocal. Great for live use at smaller gig venues.
