I suspect the term "hypo-cardioid" is what many of us would term "sub-cardioid".  No matter what the term, I imagine the reference is to a pattern between omni and cardioid.

[Klaus Heyne]

The proper term for that pattern in the mic business would be "wide cardioid" or, as Neumann calls it, "wide-angle cardioid".

[Barry Hufker]

Yes, "wide cardioid" is the industry standard term by manufacturers, but "sub-cardioid" is in common usage among audio professionals, even appearing in professional audio magazines.

"Wide cardiod" makes the most sense to me.

And to think I was technically referring to it as "a click or two towards omni..."

Geoff Emerick de Fake wrote on Mon, 23 August 2010 07:45 Are you sure? The mic body is smaller than a U87, but the capsule seems to be the same size. But the significant difference is that the 89 is an edge-terminated capsule, whence the 87 is center-terminated. No, the U89, TLM 170 and TLM 193 share the same KK89 capsule. It is smaller than the KK87 capsule

Thanks for the pix.

and a totally different design.

Yes, that's what I meant by edge-terminated vs. center-terminated.

Theoretically, that mid sized capsule has some ideal compromises. I wonder if anyone has tried it with either a simple fet amp (a la u87) or tube amp, as it seems to have only been implemented in "high parts count" amps (that rarely receive the love the simpler amps get) so far.....?

my thoughts exactly, i'm up for building such a mic - especially if people here can help with advice and info.

[compasspnt]

I have an 89 I've never liked, and never use.

Maybe I will gut it...

[Oliver Archut]

Spare the U89s life Terry, a mic like that sounds good in theory, but transplanted on a U87 amp it does sound thin with no articulation at all.

Certainly true with the stock, high frequency-compensated U87 processor. But I am stil curious what a clean processor, without the broadcast compensation and other anomalies, would do to this capsule.

Hello Klaus,

I forgot to mention that the filters were disconnected...

I recall a Gotham Audio ad for the U89 in REP exclaiming "Remember the M49?"

Is that the sound Neumann was searching for, or was that wishful thinking on Mr. Temmer's part?

As David has suggested, the capsule does have some ideal compromises...could a simple tube or FET circuit give it some sonic legs?

In that case, Neumann would have used a K49. I think that the K89 is more neutral than the K49.

The term hypocardioid is related to cardioid, with the use of the greek prefix 'hypo', the very same way you use hypercardioid.
This is the way it is taught in France.
The prefix 'hypo' means 'sub'; 'hyper' would mean 'over'?
Anyway, it is a very useful pattern for recording music in a room.
