Overview
The ST4015A Stereo Pair with 4015A Wide Cardioid Microphones from DPA is a stereo kit that consists of two matched 4015A Wide Cardioid Microphones, two microphone holders, two windscreens, and a Peli Carrying Case. The microphones are matched within ±1 dB on both frequency response and sensitivity for accurate
