The DPA 4066 CORE+ Omnidirectional Headset Microphone features a pre-polarized condenser transducer with a consistent omnidirectional polar pattern. It delivers a frequency response of 20 Hz – 20 kHz and a sensitivity of 6 mV/Pa (±3 dB at 1 kHz). Incorporating CORE+ technology, it reduces distortion across the dynamic range while maintaining high headroom (133 dB SPL RMS at <0.5% THD). Weighing 14 g with a 5.4 mm capsule diameter, it operates on 5–10 V DC power for wireless systems and includes MicroLock connectivity. Designed for broadcast, theater, and speech applications, it functions within -40°C to 45°C and supports cable runs up to 300 m.
