The TC-Helicon GO XLR is a USB audio interface for Windows that offers users an all-in-one solution for streaming podcasts, games, or similar content. The four-channel mixer, with motorised faders and freely assignable LCD labels, ensures intuitive control of the volume levels of assigned sources during live transmissions and lets you adjust both the numerous hardware inputs and several virtual audio channels on your computer (e.g. voice chat, game sound, etc.). An onboard sampler and a directly integrated effects section with a selection of vocal FX offer additional functions that are usually only available with extra hardware or complex software setups. This makes the GO XLR a complete control hub for the audio part of streaming.

The heart of the TC-Helicon GO XLR is its accompanying app, which can be used to assign the four motorised faders to the appropriate input channels, control the routing of the output channels, and set up a connected microphone (level, gate/expander, equaliser, and compressor), among a host of other things. You can connect dynamic microphones or simple headset microphones, as well as condenser microphones that require phantom power. The app can also be used to change settings for the effects, select samples for dedicated sample pads, and adjust the coloured LEDs of the buttons and faders. Another very useful function is the ability for all non-global settings to be stored in presets for different applications.

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.
