SiX-2-2 is a specialized VST effect plugin designed for Windows that converts 5.1 surround sound into stereo output. It offers precise control over multiple audio channels, including center, LFE, front, and rear, enabling users to fine-tune the balance and spatial characteristics of their mix with ease.

This plugin includes adjustable parameters for channel levels and base width, allowing distinct settings for front and rear channels to enhance the stereo image. A built-in delay feature helps minimize phase issues by letting users offset rear channel timing up to 50 milliseconds before or after the front channels, improving overall sound coherence.

Additionally, SiX-2-2 incorporates a 25 Hz high pass filter to clean up low-frequency content, ensuring a clearer mix. Its intuitive controls make it an effective tool for audio engineers seeking to downmix surround sound sources without compromising clarity or spatial dynamics.
