It uses a dual capsule of two symmetrical push-pull transducers with high linearity, which means minimal signal distortions and a strong signal. The transducers each send a separate signal, allowing the individual pick-up patterns to be adjusted and mixed together individually. This design creates two cardioid pick-up patterns, which can be selected remotely for various effects. While the microphone is highly sensitive, SPLs of up to 134 dB are possible. The strong signal created resists interference, reducing the need for additional filters.
