Configuration of the MSI Immerse GH61 takes place in the "Nahimic for Headset" software driver. It is split into two sections, Audio and Microphone.
The left side of the Audio section is reserved for a mute switch and a volume slider. On the right, you'll find four pre-made profiles (Music, Movie, Communication, and Gaming), which are activated by clicking on the effects button at the top and then selecting the desired profile. Once inside a certain profile, you can toggle the virtual surround sound and Volume Stabilizer, the latter of which basically is a software volume normalizer that crushes the dynamic range but removes peaks from incoming audio. There are three additional toggles with their accompanying sliders below: Voices, Bass, and Treble. This is a rudimentary equalizer where you can boost or decrease low, middle, and high frequencies on a massive ±12 dB scale. Each profile comes with a certain "equalizer" setting, but you're free to adjust them to your personal preference.
In the Microphone section of the Nahimic for Headset software driver is a mute switch and a gain slider on the left, and effects are on the right. The effects are Static Noise Suppression and Voice Stabilizer. The Voice Stabilizer feature aims to maintain a constant vocal level regardless of the distance between your mouth and the microphone capsule. I'll examine both of these features in the microphone performance section of this review.
