Never before has a ribbon mic delivered as much clarity and breadth of sound in a package so fit for both studio and live settings as the supercardioid KU5A.

Never before has a ribbon mic delivered as much clarity and breadth of sound in a package so fit for both studio and live use. 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 KU5A is equipped with active electronics, fit for any preamp in the studio and on the road, as well as an integrated high-pass filter to roll off low end in close range recording applications.

The KU5A’s supercardioid polar pattern captures pure, direct sound while rejecting room tone from behind the mic. This feature prevents excessive monitor and audience bleed when tracking musicians live in one room or on stage. Traditional figure-of-8 ribbons, which distinctly incorporate both direct sound and room sound, rely on sharp nulls  to reject unwanted bleed.

The KU5A’s end-address directionality and tight supercardioid pattern allow for effortless positioning on snare, toms, and other instruments that may be difficult to access. Signal bleed captured by dynamic mics and condensers often sounds harsh and brittle due to top-end frequencies. The minimal bleed captured by the KU5A sounds more natural as a result of its smooth top end and coheres well in a mix.

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.
