AEA R84A Phantom-powered Ribbon Microphone



The AEA R84A Phantom-powered Ribbon Microphone is the replacement of AEA A840 High Performance Phantom-Powered R84.

The AEA R84A is a phantom powered R84 that delivers the same award-winning sound as its passive sibling and offers you 12dB more sensitivity, thats over 4 times louder! Its higher output and immunity to impedance-loading offer more flexibility in the choice of preamps, and avoid noise problems in low signal level applications. Touring musicians who are looking for consistent and risk-free performance in a wide range of venues and recording setups will find a trusty companion in the R84A microphone.

The R84A remedies most of the limitations of passive ribbon microphones, whether in a remote recording situation with long cable runs, a classical music application, or simply for the wish to combine the ribbon sound with a low-gain vintage preamp. The signal strength and flexibility of active JFET electronics combined with the luxurious warmth of a Big Ribbon™ all wrapped up in an affordable package is what sets this microphone apart. No studio is complete without a pair of R84As.
