After tracking down the engineers who designed and built the original legendary RCA 44 ribbon microphones, AEA acquired ribbon material, made the tooling, and custom machined all the parts necessary to build the original RCA 44 B/BX design to its original specifications, in their own AEA R44CE design. Built just like they were in the 1930s, the R44CE from AEA flies in the face of every trend in modern ribbon microphone design, and to glorious results. After years of painstaking work, AEA has again begun production of the most important ribbon mic design of all time.
