It consists out of two phase-aligned capsules, a condenser and a dynamic one. You can switch between three sounds for more flexibility for studio and live applications. Unique sound for bass drums and other bass-heavy instruments. We put two phase-aligned microphones in a single housing.  The dynamic side ensures accurate attack reproduction of the kick drum, while the condenser element captures the drum's low end. Each element has a dedicated output. This enables you to shape the kick drum sound in unique ways.
