R44C (Flagship mic. Museum-Quality replica of RCA 44)

The Classic Sound of the RCA 44B!

The R44 from RCA is one of those rare mics that has remained relatively unchanged from its inception, and still sounds great some 75 years later. Wes Dooley, a specialist in ribbon mics of all kinds, has now restored the 44 type microphone to its rightful position in the studio. After tracking down the engineers who designed and built the original RCA 44, 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, just as it was in the 1930s. After years of painstaking work, AEA has again begun production of the most important ribbon mic of all time: the AEA R44C.
