The R84A from AEA Ribbon Mics & Preamps brings home the same award-winning sound as its passive sibling, the R84 (sold separately), although it features a higher output and immunity to impedance-loading, provides even more versatility in preamp choice, and avoids the noise problems of low signal-level applications. The result is that touring musicians who are seeking consistent and risk-free performance in a wide variety of venues and recording environments will find a trusty companion here. It remedies most of passive ribbon microphones' limitations, whether it's being employed in a remote recording situation – or any situation – with long cable runs, a classical music application, or just to answer the desire to blend the ribbon sound with a low-gain vintage preamp. The active JFET electronics' signal strength and flexibility, combined with the luxurious warmth of a Big Ribbon™, and all wrapped up in an affordable package is what sets this mic apart. Your studio just isn't complete without a pair of R84As.
