TC Helicon GoXLR White White Podcast Mixer

4-Channel USB Streaming Mixer for Broadcasters

The TC Helicon GoXLR White is a 4-channel USB streaming mixer that brings mixing, vocal processing, sampling, and audio interfacing into a single desktop device. You can replace multiple pieces of gear with one tactile control surface, connecting to a Windows PC via USB and managing setup through the GoXLR App.

What Sets the GoXLR Apart

At the heart of this mixer is a premium low-noise MIDAS mic preamp with switchable +48V phantom power, the same technology used in professional broadcast consoles. Four long-throw motorized faders recall their positions when switching profiles, each with its own customizable LCD scribble strip. Instantly mute the mic with a Cough button, while the Censor function generates a 1 kHz tone to bleep out unwanted language.

Audio Quality and Conversion

High-resolution conversion and a wide gain range make it compatible with any microphone.

• A/D Resolution: 24-bit / 48 kHz — broadcast-grade conversion for clean voice capture
• Preamp Gain Range: 0–72 dB — drives low-output dynamics like the Shure SM7B without external gain boosters
• Quiet recordings are ensured thanks to an EIN of -128.5 dBA, which keeps the noise floor low.

Inputs and Outputs

Every source a streamer needs is covered by the I/O layout.

• Mic Inputs: 1 x XLR + 1 x 3.5 mm TRS — supports both pro studio mics and headset lavs
• Digital Input: Optical S/PDIF (Toslink) — pulls clean digital audio from a PlayStation, Xbox, or other console
• Bring in phone audio and send it to a second PC for dual-streaming setups using Line I/O via 3.5 mm TRS.
• Headphone Output: 3.5 mm TRS — direct monitoring with app-controlled master volume

Vocal Effects and Sampler Engine

In addition to mixing, the GoXLR features broadcast vocal effects and a multi-bank sampler.

• Vocal FX: Reverb, Echo, Pitch, Gender, Megaphone, Robot, Hardtune — six preset slots recall favorite chains instantly
• Sample Pads: 12 pads across 3 banks (A/B/C) — trigger jingles, stingers, and recorded clips mid-stream
• Shape your voice fully using onboard EQ, Compressor, Gate, and De-esser without relying on third-party plugins
