Overview
The ST4015C Stereo Pair with 4015C Compact Wide Cardioid Microphones from DPA consists of two matched 4015C Wide Cardioid Microphones, two holders, two windscreens, and a Peli Carrying Case. The microphones are matched within ±1 dB on both frequency response and sensitivity to provide accurate sonic reproduction.
