AEA A440 Ribbon Microphone

Iconic, High-Performance Ribbon Mic

The AEA A440 Ribbon Microphone is an active phantom-powered big ribbon mic with figure-8 pickup pattern. It harnesses AEA’s proven JFET amplifier technology, yielding an impressive 18dB boost in output and enhancing compatibility with various preamps. Remarkably, the A440 offers higher sensitivity than most condenser mics, while maintaining an exceptionally low self-noise level.

Known for its astonishingly quiet operation, the A440 redefines the ribbon microphone experience with unmatched purity and natural response. Continuing the legacy of AEA’s “Big Ribbon” tradition, reminiscent of the classic RCA 44, it combines modern innovations with iconic performance.

Sound & Performance

The A440 delivers the classic and flattering “Big Ribbon” sound that made the RCA 44 legendary. Its figure-8 polar pattern enhances mids and lows while smoothing harsh highs. With a maximum SPL of 132dB, it handles vocals, electric guitars, orchestras, and more with finesse, maintaining the iconic ribbon warmth and character.

Design & Build

The A440 features vintage-inspired aesthetics, robust seven-pound construction, and a built-in head amp that protects the ribbon element from phantom power. Passive ribbon mics are notorious for low output, but the A440’s active JFET amplifier provides 18dB additional gain, making it compatible with a wide range of preamps while retaining extremely low self-noise.
