DPA 4090 High Sens

DPA 4090 High Sens - high-fidelity omnidirectional condenser microphone with a small diaphragm, ideal for sound capture in live or studio situations, for acoustic string instruments, piano, or reed instruments. Due to its very linear frequency response in the range of 20 Hz to 20 kHz, it can also be used as a measurement microphone for calibration. It features a compact and robust design, a 5.4 mm capsule, and a pre-polarised condenser. It delivers an open and natural sound. It comes with a windscreen, mount, and protective transport case.
