RCA BK-5B Cardioid dynamic microphone
RCA BK5 unidirectional ribbon microphone in good working order.
This is a commissioned sale for one of our regular customers. The microphone has recently been serviced here at Xaudia and has a new ribbon and cable.
The thumb wheels are replacements. Slightly scruffy condition and priced accordingly.

The RCA BK-5A and BK-5B were introduced in the early 1950s as part of RCA’s effort to provide a compact, rugged, and directional ribbon microphone suitable for broadcast, film, and television studios. At a time when large bi-directional ribbon microphones like the RCA 44 series were common, the BK-5A offered a more focused cardioid pattern optimised for studio environments where off-axis rejection, camera-friendly form factors, and the ability to withstand high-SPL environments were increasingly important.
