The AKG D12 VR large diaphragm cardioid dynamic microphoneis a large-diaphragm cardioid dynamic microphone that features an active mode with switchable filtering, as well as a normal passive mode. Designed specifically for kick-drum recording applications, the microphone has a thin diaphragm to enhance the low frequency performance. Without phantom power, the microphone is designed to deliver the natural character of the sound source. With phantom power enabled, one of three switchable active-filter presets can be used to quickly adapt the microphone response to suit the desired kick-drum sound. The filter setting can be controlled using a switch on the microphone body. In this active mode the output level is also reduced by 10 dB automatically.
