AKG was created in 1971. The AKG C414 XLS was created in 2009. It originated from the C12. The C414 was available in 2 versions. Either, the C414E, with cannon type connector or, the C414C with a connector to the “Din standard”. The C414XLS comes with a AKG custom mount, its versatile, has three attenuation levels (-6,-12,-18dB), three different switchable bass-cut filters (to reduce noise, subsonic noise or for proximity effect) and a overload warning with audio peak hold LED. By far my favourite feature is the ability to choose from multiple different polar patterns. You can switch from a cardioid pattern (heart shaped), a figure 8 pattern, a hypercardioid pattern, an omnidirectional pattern or a wide cardioid pattern. All polar patterns pictures are below.
The AKG C414 XLS gets a 5 star rating form me because I love how you can customize it so much. It makes it able to record professional studio recordings, professional stage miking, lead vocals & lead instruments, classical music recording and even ensemble recording. My experience with this is that it sounded really nice, I used it to mic over head a drum and it worked very well I had no problems with the sound. To hear it click here. Some other members in this microphones family are the C12A, the C12B, the C412 and the C414Eb.

AKG or ‘Akustische und Kino-Geräte’ is a company founded by physicist Dr Rudolph Gorike and businessman Ernst Pless. ‘Akustische und Kino-Geräte’ translates to ‘Acoustical and Cinema Equipment’ in English.

This led to a series of products that redefined the sound of recorded music. AKG created the world’s first diaphragm dynamic cardioid microphone called the
