The TC-Helicon VoiceLive Play GTX is a compact floor multi-effects unit built for the singing guitarist: vocal harmony processing and guitar effects in one box. TC-Helicon announced it on 18 January 2012 in Anaheim, Los Angeles, calling it the world's first multi-effects unit dedicated to the singing guitarist1. It is a digital design and runs on mains power1.
Vocal harmony and guitar effects in one unit
RockBoard's PedalPedia describes the GTX as a unit where "pristine vocal and guitar effects join forces in one compact, turbo-charged unit"1. Alongside the guitar side, RockBoard's PedalPedia puts pro-level effects and what the listing calls state-of-the-art harmony processing at the center of the design1. As the maker's own wording puts it:
"Quite simply, singing guitarists will feel like they have a dedicated vocal producer and an experienced guitar tech sitting inside the box"1
The GTX sits in a family of TC-Helicon vocal-and-guitar floor units. The simpler VoiceLive Play is described by the maker as the preset-driven floor processor for singers who want flagship TC-Helicon tone without programming anything, and as the entry into the VoiceLive family, ready to gig out of the box2. On that model, harmony, doubling, reverb, echo, hardtune, transducer and the Adaptive Tone engine all run in real time, with up to eight effect blocks active at once2. Players who want a larger unit in the same line can look at the VoiceLive 3 Extreme, and those after a simplified guitar-focused take on the format can compare the Play Electric. For a narrower harmony-only tool, the VoiceTone Harmony-G XT covers vocal harmony on its own.

Power and connections
The VoiceLive Play GTX is a mains-operated unit1, so it is designed to run from wall power rather than batteries.
Because the GTX is specified for mains operation1, a battery or a low-current daisy-chain supply is not the intended way to power it. Factor a proper mains connection into how you set up your board or gig rig.
The related VoiceLive Play in the same family shows the connection set typical of these units: an XLR input with phantom power for a microphone and a balanced XLR main output, plus a MIDI in connection that TC-Helicon says lets the harmony engine build musically correct backing voices behind your lead, using MIDI from a keyboard or a manually set key2. Its front-panel display walks you through every setting without buried menus2.

Questions
Is the TC-Helicon VoiceLive Play GTX digital or analog?
The VoiceLive Play GTX is a digital unit. RockBoard's PedalPedia lists its circuit type as digital, which fits its role as a preset-driven vocal and guitar processor running harmony, effects and tone shaping in software rather than with analog circuitry.
When was the VoiceLive Play GTX released?
TC-Helicon announced the VoiceLive Play GTX on 18 January 2012 in Anaheim, Los Angeles, introducing it as the world's first multi-effects unit dedicated to the singing guitarist.
Does the VoiceLive Play GTX run on batteries?
No. RockBoard's PedalPedia lists the VoiceLive Play GTX as a mains-operated unit, so it needs wall power rather than batteries. Plan your pedalboard power accordingly, since a standard battery-style supply is not the intended way to run it.
Does the VoiceLive Play GTX have MIDI?
The closely related VoiceLive Play, the non-GTX model in the same family, has a MIDI in connection, which TC-Helicon says lets the harmony engine build musically correct backing voices from a keyboard's MIDI or a manually set key. See the VoiceLive Play page for that model's details.
Where can I download the VoiceLive Play GTX manual?
The English manual for the VoiceLive Play GTX is available as a PDF from TC-Helicon's documentation, hosted on the Music Tribe media server and linked from RockBoard's PedalPedia entry for the unit.
