Km 85i ?
Author: Posted by Gregg Karukas

Hi Neumann-men,
i have a chance to buy a pair of KM 85i's and i am not familiar with the model. Is it Hyper cardiod? Rolled- off?
I currently own pairs of AKG 451's, 460's, and Rode Nt-2's and am looking to possibly sell one pair for the Km -85's if they have a distinct or better sound.
Any info/opinions would be appreciated. Thanks, Gregg Karukas
p.s Hi Klaus.

You should definitely listen before you buy. Your message didn't say what capsules you have on your 451 or 460 pairs. The nature of each capsule will change the sound.
The best way to find out what the characteristics of a model are is to start by reading the information Neumann provides on another part of this board, then asking friends or colleagues who have experience with it, then getting a pair on loan or rent to listen to over a weekend.
Audio Upgrades in North Hollywood brags that they have modifications to some of the AKG 451 line that will make them sound like Neumanns, if you want to try that route.  
What the KM 85i is

Gregg,
KM 85s are somewhat specialized microphones--cardioids that have their low frequency response reduced rather severely, so that they can be placed close to a speaking voice without excessive boominess. Of course they have other uses, but don't assume that they'll sound as warm and rich as normal cardioids, because in normal applications they won't.
The KM 85 uses the same body (amplifier) as the KM 83 omni and KM 84 cardioid. Or perhaps I should say 'used'--the whole series hasn't been made for quite a number of years.
You can look in the History section of this Web site for info on the KM 64 and KM 84, to get a general idea of what they were about, then look at the current model KM 145 which is the closest thing they have nowadays. Note especially the frequency response curve for the KM 145. The KM 85 doesn't have the same high frequency bump, but is otherwise similar. On the other hand the newer microphones are quieter and have higher overall sensitivity, as well as greater tolerance for very high sound pressure levels.
