SteelSeries Alias Pro XLR Mic Streaming Kit

The SteelSeries Alias Pro XLR Mic + Stream Mixer Kit is purpose-built for content creators who want studio-grade audio without the complexity of assembling a traditional recording chain. At the heart of the kit is the Alias Pro condenser microphone, which features a capsule three times larger than competing streaming mics. This oversized capsule captures a wider frequency range with greater detail, producing vocals that sound rich and present — a meaningful step up from the compressed, thin sound common with smaller-capsule USB microphones. The unidirectional polar pattern keeps the focus squarely on your voice, rejecting keyboard noise, fan hum, and other ambient distractions.

The included Stream Mixer serves as both an XLR audio interface and a hardware control surface. It connects to your PC via USB and accepts the Alias Pro's XLR output, giving you physical dials and buttons to adjust mic gain, monitoring levels, and audio mix without leaving your game or stream. For dual-PC setups, the mixer can bridge audio between a gaming rig and a dedicated streaming machine through its dual connectivity. Paired with SteelSeries' free Sonar Software — which provides parametric EQ, noise gating, and virtual audio routing — the kit offers a complete, integrated audio solution that minimizes the need for third-party software or additional hardware.
