Instead, the Stream Mixer focuses on features more immediately useful to gamers and streamers. An LED ring surrounding the gain knob glows a subtle green when turned on but will get brighter, then turn yellow as the microphone input gets louder. It will eventually turn red if the audio peaks. This is a handy way to keep an eye on your mic levels without being distracting. If you tend to yell during your games, this can be a godsend to your teammates or viewers.
The giant dials are easy to adjust without looking directly at them. The volume knob is large, flat, and easy to grab quickly to avoid blasting your ears off. The gain knob for the microphone feels considerably different. It's thinner and has a gentle curve toward the bottom. It's hard to mix these up and grab the wrong one if you're busy paying attention to your game.
As I mentioned before, the mute buttons for your mic and PC audio are large and easy to press quickly. Use SteelSeries' Sonar app and you can tweak the buttons to add fades and transitions that can make for a smoother experience if you're streaming.
Sonar's Superpower
Out of the box, the Alias Pro mic sounds great. It picks up solid bass tones while vocals are crisp and clear. If this XLR mic came on its own, I'd plug it into my existing interface and be quite happy with it. But its real strength shows up when paired with Sonar. We've discussed SteelSeries' Sonar software in prior reviews and it continues to be one of the biggest perks of the company's hardware.
With it, you can customize levels and profiles for different games, balance team chat with game audio, and adjust your microphone volume. And with the Alias Pro, it also has an array of equalizer presets that help you coax even better sound out of the mic. I used one of the built-in presets and got something very near that clear, podcast-voice sound without requiring any additional editing.
For streamers, Sonar takes on a new role as a sound mixer for broadcasting via the Streaming toggle. The app can take in up to five audio inputs, remix them, and output the mixed signal. This is a task that's often handled by either a physical mixing board, or in apps like OBS, but Sonar has some extra tools to equalize audio signals in a simplified interface.
Most streaming apps only have rudimentary tools for mixing audio levels from different sources. Sonar takes this concept a step further. For each of the five inputs Sonar can mix, you can set separate equalizer settings tuned to the type of audio you're sending the app. So, for example, you can apply one EQ to video game audio, a different one to your microphone, and another to your team chat via apps like Discord.
SteelSeries provides some presets tailored to several popular games, like Valorant, Fortnite, and CS: GO. A few of these presets are specifically designed to highlight certain sounds, like the CS: GO preset, which elevates some of the higher frequencies used when an enemy places a bomb. I'm more of an Overwatch guy, and many of the presets–including the Overwatch 2 one–are more basic EQ adjustments, so I can't speak to how effective they are at providing a competitive advantage.
