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 filter setting
can be controlled using a switch on the microphone body. In this mode
the output level is also reduced by 10 dB automatically.

Description
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.

Description
a Without phantom power the D12 VR operates as a normal
dynamic microphone. The three active filters are bypassed and do
not affect the audio signal.
b When connected to a standard phantom power supply (P48V) the
output level is automatically reduced by 10 dB and one of three
active filter presets can be selected using the three-way switch.
1) Switch in left position (green LED)
The midrange filter is applied as
in Position 2 and a low-end
boost enhances the power of
the kick drum.
Recommended for use with
open kick drums.
2) Switch in centre position (red LED)
A mid-range attenuation filter is
active, providing more space for
other instruments in the mix.
Recommended for achieving a vintage sound.
3) Switch in right position (blue LED)
The mid-range and low-end filters are applied as in positions 1
and 2 as well as a high-end boost to enhance the presence of
the kick.
Recommended for use with closed kick drums.
The switch position is clearly represented by the colour coded LEDs
and hence the filter selection can be determined with ease.

Application / Cleaning
Most engineers agree that it is beneficial to remove the front head
when miking up the bass drum. A full drum sound is obtained by
placing the microphone just outside the drum. The further inside, the
drier and less boomy the sound and the better the acoustic separation
of the bass drum from the rest of the kit. Pointing the microphone right
toward the beater produces a harder sound culminating in a "click"
when the microphone is as close as 1 or 1.5 inches to where the
beater strikes the head. Directing the microphone away from this
point, toward the rim of the head, will mellow the sound.
xUse a soft cloth moistened with water to clean the surface of the
microphone body.
