Curio's - Neumann's KK50 capsule assembly - Later type K50 capsule |
|
|
Up-to-date materials |
|
|
As time moved on, so diaphragm material and design was changed. Moving away from Aluminum foil, towards the more predicable and reliable gold sputtered Mylar film. New capsules were manufactured to replace the earlier designs. Therefore various examples can be found in the KK50 capsule assembly. |
|
|
The later type of the KK50 capsule assembly, utilised a capsule very similar to that used on the later KM53, and KM63, miniature Omni directional valve microphones. Which are themselves very similar capsules to those used on the KM73 and KM83 FET type microphones. |
|
|
Capsules types being KK** i.e. An M50 uses a KK50 capsule assembly etc. |
|
|
Electrical connections, in common with all K50 capsules, being a small pin protruding out of the front face of the capsule case and a pin protruding from the rear of the capsule. |
