Desktop broadcast mixer with USB audio interface — TC Helicon GoXLR Mini White

The TC Helicon GoXLR Mini White is a desktop broadcast mixer and USB audio interface built for live streamers, podcasters, and content creators. The compact white unit creates multiple virtual USB audio devices in Windows, so each app gets its own fader without tabbing out mid-stream. It pairs the award-winning Midas mic preamp with built-in studio processing, letting one small box replace a stack of separate gear on a creator's desk.

Hardware routing and on-board vocal processing

What sets the GoXLR Mini White apart is hardware-based audio routing and on-board vocal processing. The Midas preamp delivers 70 dB of clean gain — enough to drive a Shure SM7B without a cloudlifter — and the unit ships with a 48 V phantom power rail for condenser mics. A dedicated Cough button mutes the mic instantly, while the Bleep button drops a censor tone over the broadcast to keep streams family-friendly.

Connectivity and signal flow — broadcast mixer I/O

Streamers juggling game audio, voice chat, music, and a microphone need every source on its own controllable channel. The GoXLR Mini White exposes the right ports to make that routing painless.

• Inputs: Optical S/PDIF, XLR, Jack 3.5 mm TRS, Jack 3.5 mm TRRS — covers consoles, broadcast mics, headsets, and mobile devices from one desktop box
• S/PDIF Optical Input — pulls clean digital game-console audio in without routing through a capture card
• Headphone Output Port: 3.5 mm jack — front-panel monitoring with software-routed source selection

Microphone preamp and power — broadcast-quality voice chain

The mic input is the heart of any streaming rig, and the GoXLR Mini White leans on TC Helicon's Midas heritage to deliver quiet, transparent gain with enough headroom for demanding broadcast dynamics.

• Mic Preamp: Midas (ultra-low noise) — 70 dB of clean gain drives SM7B-class dynamics without external boosters
• Phantom Power: 48 V — powers studio condensers and active ribbon mics straight from the unit
• Number of Channels: 2 — two physical mic/line paths plus software sub-mixes for full routing flexibility

Form factor and software control — desktop streaming rig

At roughly 168 × 132 × 70 mm and 0.73 kg, the GoXLR Mini White sits unobtrusively beside a keyboard and mouse. The companion Windows app handles routing, lighting, EQ, compression, gating, and profile recall.

• Dimensions: 168 × 132 × 70 mm — compact desktop footprint fits any streaming setup
• Weight: 0.73 kg — light enough to reposition between sessions
• USB 2.0 Connection — plug-and-play with Windows; the app exposes up to 12 virtual audio devices for per-app fader control
• Bluetooth: No — wired-only design keeps latency predictable for live broadcast
