AEA Microphones KU5A Supercardioid Ribbon Microphone

Add to Wish List
The supercardioid KU5A breaks new ground in ribbon technology with its acutely focused directionality that rejects bleed from other instruments, room reflections, and loud ambience in the studio and on stage.

As a near-field ribbon designed for close range recording, the KU5A delivers the low-end heft and pronounced midrange one expects of AEA ribbons and with moderate, manageable proximity effect. Vocalists can sing directly into the grill of the KU5A, as its interior components are the most protected of any in the AEA lineup.

The active KU5A comes complete with a custom transformer and JFET electronics. It features the same custom transformer as the A440, R84A, and NUVO ribbon mics, providing greater output, less audible noise, and stable impedance. This allows for consistent frequency response and greater flexibility with different preamps, including those within audio interfaces. The boosted output of the KU5A is beneficial when recording quiet sources like vocals and soft acoustic guitars, and the active circuitry prevents noise interference. The KU5A operates with standard 48-volt phantom power.

This mic is insanely good! The rejection is like an sm7b, but the clarity is like a high end condenser, but with that smoooooooth ribbon mic sound, yet not dark and virtually no sibilance. Instant classic!
