Thank you for your interest in our Neumann AK 50 microphone capsule.  This AK 50 is in mint condition, sounds great, and has been well taken care of.  It comes complete with Neumann top and bottom capsule caps, to protect the diaphragm and the XLR connector.

The AK 50 is a member of Neumann's top-of-the-line and very versatile, KM 100 miniature microphone series.  The KM 100 series is  comprised of the KM 100 microphone amplifier body and seven "AK" designation capsules.  The AK 50, combined with the KM 100 body, is called the KM 150 hypercardioid microphone.

The KM 150 is ideal for for close miking of acoustic instruments and sound sources of all types.  It is especially useful for attenuating unwanted sound of nearby instruments and/or avoiding problems with feedback.  The KM 150 is equipped with a 10dB attenuation switch, allowing SPL levels up to 152dB.  This makes the KM 150 ideal for close-miking guitar amps, drum kits, snares, toms, cymbals, congas, and for use as stereo overheads.

Brand-new, the Neumann AK 50 has a retail price of $1,598 and a street price of $1,041.

 We like the KM 150 so much, we have ten of them!  We recently sent all ten to John Peluso (Peluso Microphone Lab) for inspection, testing in his anechoic chamber, and hand-matching.  All ten KM 150 mics, including this capsule, passed with flying colors.  Amazingly, all ten proved to be extremely close to each other in frequency response, demonstrating the outstanding quality and manufacturing standards of the Neumann KM 100 series.

We've decided we don't need all ten KM 150 mics, so we're selling a few mics and capsules to thin the herd and bring in funds for our new studio.   We're keeping the KM 100, to dedicate to an AK 20 figure-8.
