RK-87C Microphone Capsule
The RK-87C is a true 34mm, dual-backplate large-diaphragm condenser capsule. It is based on Neumann's K87/K67.
The backplates are solid brass, machined to high precision tolerances. The diaphragms are ultra-thin, 3-micron Mylar. The front diaphragm is metallized with gold.
The "C" suffix in the product name indicates that this is a Cardioid-only capsule. Therefore this capsule should not be used in a multipattern microphone.
The RK-87C includes our "supersaddle," two M1.6 metric machine screws to attach the capsule to the saddle, a backplate termination wire, and the short screw needed to connect the wire. The front diaphragm wire is already installed on the capsule. No mounting post is included with this capsule.The installation procedure for the RK-87C is the essentially same as for the RK-87; see those here. You will not need to ground the two backplate halves together, as pictured on that page; instead, simply screw the included blue wire into the backplate.
