TC-Helicon VoiceLive 3

The VoiceLive 3 has two outputs available (Vocal and Guitar) but I choose the LEFT output and run MONO so that I can make the connection with one cable. I don't use Compact Channel 1 when I'm using the VoiceLive 3.

I prefer to use an adapter (XLR to ¼ inch jack) from the VoiceLive 3 left out - to Compact Channel 2. That way you don't have to work around the Compact's internal microphone Preset.

Compact Channel 2

There's MIX button on the VoiceLive 3 that brings up a screen where it's easy to control the relative volumes. Vocal volume is set. You can raise and lower the other inputs on the VoiceLive 3. The VoiceLive 3 does not have a master volume level control. So you will need to control overall level at the Compact.. And it's nice to use just one cable from the VoiceLive 3 to the Compact. This also keeps the Compact Channel 1 free in case I need to plug in another microphone.

I use an adapter like this

Neutrik NA3FJ XLR to ¼ inch jack Tip-Ring-Sleeve female or Planet Waves XLR female to ¼ inch jack Tip-Ring-Sleeve female

NA3FJ Neutrik 3 Pin XLR Female to 1/4" TRS Female Locking Barrel Adapter


xlr female to 1/4 female adapter


Balanced ¼ inch jack Tip-Ring-Sleeve cable or Unbalanced ¼ inch jack Tip-Sleeve cable

¼ inch jack Tip-Ring-Sleeve


¼ inch jack Tip-Sleeve

OR a longer version of a cable like this:
