How is the R44 different from other ribbon microphones ?
The 44 was RCA's best microphone from the 1930s into the '50s. Is AEA's R44 that good? Both listeners and measurements say
that the R44 is better and, we've been listening to both users and ex-RCA engineers for over 25 years. We start by using only rib-
bon material originally manufactured for RCA. Next, we use modern magnet technology which is much more robust than period
magnets. We also combined the original American undamped ribbon design with the British RCA 44 innovations that lower the
weight and hum sensitivity.
The R44 design runs contrary to all current ribbon microphone manufacturing. It is large and heavy when other microphones are
smaller and lighter. The internal ribbon element is by far the longest and its resonance tuning the lowest of today's ribbon micro-
phones. It is a pure undamped ribbon design, an approach that has been out of production for over 50 years while remaining in
continuous studio use. It is different, and its sound is unique.
The R44 sounds good on everything. Leave it out and use it whenever you need to do a quick take. Bruce Swedien particularly
likes them on vocals, Joe Chicarelli on sax, Allen Sides on electric guitar. Everyone has a favorite use and everyone finds they
sound good anywhere: brass, woodwinds, percussion, strings or voice work.

RCA 44 ribbon microphones have remained an essential part of studio
life well after RCA stopped manufacturing them in 1955. The sound
and response of the 44 B/BX were unlike anything else available,
and was cherished for its smoothness, forgiving nature and unique
tonal balance. As collectors began to buy up the supply of RCA
44's through the 90's, the availability of this wonderful ribbon mic to
the studio was greatly endangered. Wes Dooley, a specialist in rib-
bon 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 mate-
rial, 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.
