AEA R84 Passive Ribbon Microphone

The R84 series quickly endears itself to engineers and musicians due to its remarkably expansive frequency range, complete with sweeping highs and booming lows.

The R84 series’ balanced and manageable proximity effect bolsters the low-end of vocals, drums, and brass, from just feet away. A ribbon mic as multi-purpose, lightweight, and maneuverable as the R84 is well-suited for both close-range and ambient mic applications.
