AKG REFERENCE LARGE-DIAPHRAGM DYNAMIC MICROPHONE

The D12 VR is a large-diaphragm cardioid dynamic microphone.
Designed specifically for kick-drum recording applications, the microphone has a thin diaphragm to enhance the low frequency performance.
Without phantom power, the microphone delivers the pure 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. The warm sound is realized by the original C 414 transformer from the 1970's and a patented discrete circuitry. The filter setting can be controlled using a switch on the microphone body. In this mode the output level is also reduced by 10dB automatically.

Active filter operation:
The implementation of an active electronic filter in a dynamic microphone is an AKG
patented solution. "Phantom Power" must be supplied from the connected mixing desk in order to power the active filter circuitry.
The operating principle of the active filters is based on analogue circuitry combined
with a transformer. Frequency processing is performed in the filter circuit and then
combined with the audio signal in the transformer. Impedance differences between the microphone and other equipment are cancelled out enabling a perfect sound regardless of the connected device.
The resulting sound is especially impressive at high signal levels at which the transformer
enhances the audio signal.
