If the TLM102 is alike KK89, what Martin Schneider mentioned on the Neumann board, I would not call the new TLM102 a cheap piece of gear designed for the hobby-market. The TLM102 is not derived from the BCM104 as I speculated before, but both have non-middle connected capsule.
23-10-2003 I wrote on the Neumann Pinboard.
Dear Mr. Peus,
As a fan of non middle connected capsules (perimeter?)the TLM 170, TLM 193 and U 89 always were my favourites. When I started to look at the diagrams of the BC 104 I must conclude the capsule has one menbrane, and it has no middle connection, and belongs to the group K89 of 'not too large diaphragma' microphones. Is the BC 104 capsule derived from the good old K89 capsule? I expect the BC 104 to be a very interesting microphone,not only for broadcast.
From Stephan Peus I received this reply.
Dear Mr.Sikkema, The K89 capsule (U89, TLM170, TLM193)is connected inside at the insulated back electrode, i.e.not at the membrane's perimeter. The membrane is connected to the capsule housing. That means the complete ouside of the capsule is ground. Therefore the capsule is totally shielded and insensitive to any kind of dirt and pollution. The same is right for the 'K104' we are using for our latest baby BCM104 broadcast microphone. This capsule has not been 'derived from the good old K89' but from 'the good new D-01' !
With best regards Georg Neumann GmbH, Berlin Stephan Peus
If the TLM102 is a medium seized membrane a la KK89, without backmembrane, I must say I am looking forward hearing this microphone.
