Audio Engineering Assoc R44C

The R44C is a museum quality replica of the 1936-38 RCA 44, hand made by AEA using 1.8 micron ribbon material originally manufactured by RCA. Features a Black and silver "radio" finish with bright polished chrome grill, cushion mount, and a bronze investment cast yoke. R44C parts are interchangeable with the original RCA 44B and BX. Supplied with hard wired two meter XLR output cable, shock mount / mic stand adapter, and AEA 44 VC vertical case for proper shipping and storage.
