AKG C422

The AKG C422 was used by Abba on vocal duties in the video for Gimme Gimme Gimme. This microphone lends itself well to two singers, although they are probably miming ing the video.

Technical description taken from the 1988 AKG catalogue linked in the further reading:

"Stereo microphone with two vertically stacked twin diaphragm elements (CK 12 large diaphragm capsules as used in the C 414 B·ULS) The upper transducer can be rotated through 270° with respect to the lower one for adjustment to different stereo base angles The entire microphone head is rotatable through 45° permitting a quick change from MS to XY recording when the microphone is fixed to the stand adapter or spider suspension . Two narrow beam LEDs mounted on the sound entry side of the two capsules enable the base angle to be checked immediately. even from a distance. in a concert hall or studio. The LEDs are powered from the S 42 E remote control by either a conventional or a rechargeable 9V battery which may be continuously charged by the phantom supply via a trickle charge circuit. The 10 and 20 dB preattenuation pads for each channel can be switched in and out by a common switch. A threaded hole on the microphone shaft accepts the knurled head fixing screw on the H 15/9 spider suspension. The case is finished matte black. Three basic polar patterns (omnidirectional, cardioid, figure 8) and 6 intermediate stages per channel can be selected on the remote control.
