Although AKG started off in the movie and theatre equipment supply business, their first commercial products were actually studio headphones. To this day their range of headphones, including the ever popular K240MKII and the K271s, are still studio staples. But it is certainly in the world of studio microphones that AKG are best known.
The AKG C12, first produced in 1953, spawned the legendary Telefunken Elam 250 and 251 which are still beloved by producers, artists and engineers the world over. Whilst the modern AKG version of the C12, called the C12VR has certainly fallen out of favour, AKG still produce a few microphones that grace most studio microphone lockers.
The C451B is a well used mic in drum recording, being a small diaphragm condenser and perfect for capturing transient detail. The C414XLS and C414 XLII are still used in project studios as a versatile and well spec'd mic (indeed some artists won't use anything else). The D112 is the classic kick drum mic, though purists aren't always enamoured over the modern voicing of these.
Despite no longer being held up as a paragon of professional microphone manufacturing as it once was, AKG remains one of the most popular mic brands in the world due to the versatility of the mics and their effortless reliability.
