R84A
Ribbon Microphone
From AEA:
R84 series ribbon microphones deliver the classic tonality of the legendary R44, with extended top-end and reduced proximity effect for mid-range and close-range recording. The R84A is an active version of the passive R84 that allows compatibility with a wider range of preamplifiers.
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.
Tightly match mic sensitivity and frequency response within .5 dB available for any pair of like mics except KU4s, KU5As, R88s & R88As.
