RCA BK11 Ribbon microphone

The BK11 was the last of RCA’s ‘large’ ribbon microphones and has a figure-8 pattern and three position filter to compensate for the proximity effect when used up close for speech or vocals. The output impedance can be set internally for 30, 150 or 250 ohms.

New ribbon and cable. Comes with a thread adapter for either 3/8″ or 5/8″.

You can read more about the BK11 at the Coutant website….


If you are looking for a stereo pair then please ask – I can supply a second microphone.


This is a commissioned sale for one of our regular customers. The microphone has been serviced and tested at Xaudia and carries a 6 month warranty.
