Compact dynamic instrument microphone
The AKG D40 is an entry-level light-weight dynamic microphone, designed for recording low-mid range instruments in live environments such as drums, percussion, wind-instruments and guitar amps.
Note that this mic comes with a wide cardioid polar pattern (without the 180° null point ).
It’s equipped with AKG’s patented varimotion diaphragm (thick) thats capable of dampening high resonance peaks, producing a clean and balanced output for high-impact instruments such as drums.
The effective frequency response bandwidth of the AKG D40 ranges between 50Hz – 20000Hz.
The mic has got an almost flat response in the lower mids, however has a smooth boost in the presence range with a peak gain of 6.3dB centered at 4.4kHz. In the upper-highs, there is another sharp gain of 3.75dB at 15kHz. This can be useful in capturing a crisp, detailed attack along with the high-quality sounding (harmonically rich) air in instruments.
Overall, the AKG D40 has a natural, sharp tone.
As a sidenote, this microphone should not be confused with the D40-S, which is another totally different microphone (a handheld dynamic vocal mic from AKG).
