The KM 100 is "small microphones" static equipped with active capsules (AK)
There are currently seven different models of AK for all uses (see the site Neumann).
Mechanically, the capsules are quite fragile (the AK40) in particular. You must be very very careful. For example when screwed or unscrewed the cap on the body, small legs with openings can become detached ... the fillets are thin and can easily seize up ... They need to be lubricated from time to time.
But if one is careful, there is no problem. And it reminds me of the KM84 and more sober. It is less "sweet" as the 184. In short, it is for me the best small microphone now manufactured by Neumann with a fantastic versatility.
Interchangeable condenser microphone capsules, the head "40" is cardio. Purpose. attnuateur-10dB in the body "100". cpasules there are "30" omni and "50" hypercardio.
10 years of use, I had a good shot the era (8000ff for the couple) so I did not hsit long is a micro "do everything", overheads drums, djembe, accordion, guitar, voice, single or couple stro ... everything passes it's the end of my park. bright and pretty sharp, good overall balance for work afterwards.
nowadays the qualitprix remains excellent, there are forcmment trs correct for much less but the price is high level of demand ...
