AKG C24 vintage stereo tube mic

The AKG C24 is the stereo version of the famous AKG C12 (Telefunken ELAM 251) tube microphone introduced in 1956. Alongside the Neumann U47, the C12 (ELAM 251) is probably the most sought-after and most expensive microphone in the world. The nice thing about the stereo version is the flexibility. Even if you only want to record in mono, you basically have two C12s in one thanks to the two capsules and two transformers. So you can either connect only one of the capsules, i.e. above or below, or e.g. use both frontally as a cardioid and record one signal unprocessed and the other e.g. compressed. There are simply so many possibilities.

The microphone offered here will be repaired and completely overhauled before it is sold. Interested parties are welcome to contact us in advance to discuss details. Will be delivered as shown.

From the original brochure:
"The C-24 was specially designed for intensity stereo recording techniques in the XY or MS mode. Two twin-diaphragm condenser microphone capsules are mounted within the microphone body, with a spacing of only 1 1/2", making any difference in time between the two outputs negligible. The upper microphone system may be rotated 180 degrees to provide any offset angle desired. Nine different directional patterns can be remotely selected for each of the two twin-diaphragm capsules. These patterns are identical as to their phase relationship and sensitivity and maintain their polar characteristics independent of frequency. The patterns are a) omni directional, b) cardioid and c) figure-eight, plus 6 intermediary positions.

The stand connector is designed to facilitate rapid and accurate change-over from MS to XY stereo recording technique. A window indicates the symbol MS and upon rotating the stand connector by 45° counter·clockwise the symbol XY indicates the correct XV position.

The C-24 system consists of microphone preamplifier with two twin-diaphragm capsules, S-24 dual remote control pattern selector, N-24 a.c. power surply, MK-24/20 cable for connecting microphone and power supply, RL-24/10 cable to connect power supply with pattern selector plus NF-24 audio cable."
