The DPA ST4011C is a complete stereo pair with two carefully factory-matched first order cardioid microphones. The specially selected DPA 4011C microphones are matched within ±1dB on both frequency response and sensitivity.

The principal appeal of the 4011C is its directional quality and attention to detail. The first-order cardioid pickup pattern provides optimised separation between sound sources. It can handle incredibly high sound levels and even includes a 20dB pad switch in the centre of the XLR connector to attenuate the output of the microphone. It provides a flat on-axis frequency response and excellent phase response
