The ST4006C Stereo Pair with 4006C Compact Omnidirectional Microphones from DPA is a kit that includes two 4006C Microphones, two microphone holders, two windscreens, three grids, and a foam-lined Peli carrying case. The microphones are matched within ±0.5 dB on both frequency response and sensitivity, providing accurate sonic reproduction from both mics. The 4006C’s size and omnidirectional pattern allow them to be mounted or hung in concert halls that require AB stereo microphone pairs.
