TC HeliconVoiceLive Play Vocal Effects Pedal
1/5
Independent shopping perspective
The Korena take
Compact vocal effects pedal for a singer running into a PA. Mic in, balanced XLR out, footswitch control. For gigging and practice, not studio racks.
Strong match
Who this is for
- Solo singer-guitarist plugging straight into a PA or mixer
- Rehearsing quietly at home through the headphone jack
- Singing over backing tracks fed into the aux input
Consider the trade-offs
When to look elsewhere
- Bands needing multiple vocal channels — one mic input only
- Players wanting to process instruments; it's built around a mic input
- Anyone needing battery power for busking away from an outlet
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Mic input handles -42dBu to +13dBu
Wide enough range for a quiet whisper up to a loud belted note without you touching a gain knob mid-song.
Detail 03
USB-B with audio I/O
Doubles as a computer interface, so the same box records vocals and updates firmware or moves presets.
Detail 04
Aux input at +2dBu
Phone or laptop plays backing tracks through the unit, so you monitor yourself and the track together in headphones.
Detail 05
1/4 inch TRS pedal jack
Accepts an external footswitch for hands-free preset changes while you're holding an instrument.
Detail 06
2.1 lb, roughly 8 x 6 inches
Fits in a gig bag pocket and sits on a table or floor without needing a pedalboard rebuild.
Final check
Know before you order
- 01No microphone included — you supply the mic and XLR cable
- 02Powered by an external supply, not batteries; you need a wall outlet
- 03The footswitch for the pedal jack is a separate purchase
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use this with headphones only?
Yes. The 1/8 inch stereo headphone jack lets you practice silently, and the aux input mixes in backing tracks so you hear yourself over the music.
02Will it work as a USB audio interface?
Yes. The USB-B port carries audio in and out alongside firmware updates and preset management, so it can record vocals into a computer.
03Does it run on batteries?
No. It uses an external supply accepting 100 to 240 VAC at under 14W, so it works internationally but always needs a mains outlet.
04How do I connect it to a PA?
Balanced XLR out into a mixer or powered speaker's mic input. Output level is +2 dBu at 0dBFS with 80 ohm balanced output impedance.
