AEA R44C

DIFFERENT Outsides, THE SAME SOUND

AEAs 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 manufacture three different versions of the R44 and an optional hotrod.

At the core, every version of the R44 sounds the same when powered with a ribbon preamp. The major differences between the versions are the exterior look and the amount of output level.

The R44 Variants

The passive R44 is available in two exteriors– the original museum-quality replica R44C and the aesthetically cost-effective R44CE. Both mics have an identical sound and are exactly the same on the inside. The difference between the two is only cosmetics and price.

The active A440 is a preamp-flexible R44 with 18dB of extra output. It is custom-painted with the RCA classic umber-colored transformer case.
