continued to be involved with microphones and acoustics as a consultant, and never lost his love for 
RCA microphones. He taught Wes Dooley in 1981 how to re-ribbon the RCA 44 with no premonition 
that 15 years later we’d collaborate on returning the 44 to production and widespread studio use. Jon 
Sank died but a few weeks before his favorite mic, the 44, was reborn at the 1998 AES Convention.

The AEA R44, manufactured by hand at our facility in California, faithfully reproduces the 1936 
original’s every strength. “Our ribbon mics evolved from our creation of accurate replacement parts 
for the classic RCA studio ribbons,” explains Dooley. “In the process we brought a legend back to 
life.” AEA’s first ribbon mic, the now classic high-output R44, continues gaining converts with its 
natural sound, articulate midrange and forgiving nature. Our 20 years of experience with various 
versions of the RCA/AEA 44s and England’s Coles 4038, was the apprenticeship we served before the 
development of the R84.

This sensibly priced high-performance LRG microphone is a significant breakthrough for performance 
and value. The R84 is a versatile performer, with a ribbon element 100 percent larger than other 
manufacturers, which delivers exceptional headroom while maintaining an intimate performance 
quality with smooth highs and extended lows. Protect it from puffs of air,

 

phantom power, and “tramp 

iron” and the R84 is nearly invulnerable. Treat it well and it’ll outlive you.
