AKG D 12 E Cardioid Dynamic Microphone
AKG D 12 E Cardioid Dynamic Microphone
Universally acknowledged as the bass-drum microphone par excellence, the AKG D-12E has won worldwide acclaim for its special ability to capture and enhance the sonic impact of this extremely low-register percussion instrument. (The versatile D·12E is not restricted to just this one application though. Other instruments that also reach down into the very lowest octave of music – the E-flat electric guitar, low-frequency driver of the Leslie, string bass, deep brass and woodwinds, etc. – are all rendered with exceptional warmth and fullness by this time-tested microphone.) Equally important is the D-12E’s corresponding ability to provide such pronounced bass cleanly – without unwanted boominess or muddiness, and without susceptibility to various forms of low-frequency noise.
This difficult (and seemingly contradictory) blend of features is achieved in the D-12E through a judicious combination of design elements. To start with, a moving-coil transducer having an unusually large diameter diaphragm and highly linear large excursion performance is coupled to a special bass-resonator chamber. This assembly is then acoustically integrated with a housing of optimum size and shape for its intended application. The result (as shown in the curves and data below) is a remarkable microphone offering: (1) useable response extending down to 30 Hz; (2) pronounced but smoothly contoured proximity-effect boost extending into the bass region well below 100 Hz; (3) low-distortion output – even in close proximity to any of the low-frequency high-amplitude sound sources mentioned above; (4) good rejection of acoustic feedback and background noise at virtually all frequencies.
In addition, the D-12E’s transducer element is specially spring suspended for superb isolation from the effects of handling noise, mechanical shocks and spurious low-frequency vibrations. As still another precaution, the transducer incorporates a hum-bucking winding to cancel the effects of electromagnetically induced noise from ever-present power and lighting cables as well as from dimmers, power switchboards and the like.
