RCA Type BK-5B Ribbon Velocity Microphone |
||
The RCA model BK-5A microphone was introduced in 1954 and promoted as a replacement for the model 77-D. It was a high quality ribbon velocity unit that was recommended for FM and TV work. It is a unidirectional design, with maximum sensitivity on the main axis (i.e. when talking directly into the grill end). An updated version, the BK-5B (as shown here) was introduced in the early 1960's. It is shown mounted on an RCA model 91-C desk stand. | ||
