Acoustic features
\nAK 20 is a pressure gradient transducer with the figure-8 characteristic, realized with a single diaphragm. The diaphragm diameter is just 16 mm. All sound field components reach the diaphragm directly. This results in identical frequency response curves and output levels at 0\u00b0 and 180\u00b0 sound incidence. Corresponding accessories allow combining the AK 20 with other active capsules or microphones to obtain an MS-Stereo setup. <\/p>\n
AK 30 is a diffuse-field equalized pressure transducer with a flat frequency response up to 10 kHz (in the diffuse field). In the free sound field this microphone has a boost of approximately 7 dB at 10 kHz. <\/p>\n
AK 31 is a free-field equalized pressure transducer with a flat frequency response up to 20 kHz (in the free field). In the diffuse sound field this microphone has a high frequency roll-off above 5 kHz. <\/p>\n
AK 40 is a pressure gradient transducer with cardioid characteristic. The frequency curves are very smooth and match 0\u00b0 sound incidence. Sound from sources within a pickup angle of \u00b1 135\u00b0 is reproduced without any coloration. <\/p>\n
AK 43 is a pressure gradient transducer with wide-angle cardioid characteristic. Attenu- ation at 90\u00b0 is 4 dB, at 135\u00b0 it is 8 dB and at 180\u00b0 it is 11 dB. The frequency response curves for sound sources within an angle of \u00b1 90\u00b0 are parallel up to 12 kHz. <\/p>\n
AK 45 is a pressure gradient transducer with cardioid characteristic, similar to the AK 40. However, it has an acoustic bass roll-off that is useful during applications when subsonic and low frequencies may cause difficulties. The AK 45 is optimized for a flat low frequency response at a recording distance of 15 cm (\u201cspeech cardioid\u201d). <\/p>\n
AK 50 is a pressure gradient transducer with hypercardioid characteristic. Attenuation of sound incidence from the side or rear is about 10 dB, with minimum sensitivity at an angle of 120\u00b0. \u00bb<\/p>\n","protected":false},"excerpt":{"rendered":"
