N28

Ribbon Microphone

From AEA:

The AEA N28 delivers the velvety sound of classic ribbon mics - but with added mid range presence, precise stereo imagery, and truly impressive performance specs.

The AEA N28 is a compact active stereo ribbon microphone consisting of two matched bidirectional (or figure-of-8) ribbon transducers in a fixed Blumlein configuration. The N28 offers an effortless way to capture natural stereo, providing an authentic representation of a performance in its environment. Distinguishing itself from other AEA Stereo Ribbon Mics, the N28 is compact, maneuverable, and easy to use, making it ideal for a wide range of applications without the need for a multi-mic setup.

Whether for drum overheads, room ambience, or close-miked stringed instruments, the N28 delivers a phase-coherent, accurate response. Its mid-forward frequency response, tamed proximity effect, and quick transient response make it versatile across various sources. The N28 excels on darker sources and is a practical solution for capturing a stereo image without drawing attention to the mic itself.

Tightly match mic sensitivity and frequency response within .5 dB available for any pair of like mics except KU4s, KU5As, R88s & R88As.
