The AEA R44-series microphones all share the authentic sound, feel and look of the 1936-38 RCA 44BX. The R44 series microphones are all detailed, hand-crafted replicas, using parts that are made to be interchangeable with an original RCA 44. They even feature ribbon material originally manufactured for RCA. The original 44 microphones were constantly updated during their twenty years of production, and after carefully looking at some of the technical modifications, we at AEA decided to adopt the British engineering from RCA that reduces the mic's weight and hum sensitivity. The R44C was designed to meet or exceed the output of a brand-new RCA 44. It is a museum-quality replica, featuring a bronze investment cast yoke, superior to the original zinc yokes by RCA (which tend to corrode over time), a hand-polished cushion mount and a cloth-covered Accusound Silver Studio Pro cable. The R44CX is a high-output, red-badge version of the R44C, specially designed for scoring and other applications demanding a wide dynamic range with the "classic 44" sound. The cost-effective R44CE features the exact same ribbon, transformer, and luscious sound as the R44C, but with a simpler, economical exterior trim. This version features a one-piece cushion mount, a formed steel yoke with satin nickel finish, and a star-quad XLR output cable. Finally, the R44CXE is the high output version of the R44CE combining the economical finish with the higher output of the R44CX.
