KU5A
Super cardioid. Super versatile. Super durable.
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 settings as the supercardioid KU5A.
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.

Sources within 3 inches of the KU5A will benefit from the warm tonality of its proximity effect, and the mic can handle 141+ dB SPL at 1kHz. High volume sources will not damage the KU5A’s interior components, so the mic can be positioned just inches from a guitar or bass amp. However strong bursts of air may damage the ribbon, so exercise caution when positioning it in front of a kick drum. Air bursts produced from vocalists will not damage the KU5A ribbon, as it is the most protected of any mic in the AEA lineup.
The KU5A has an integrated electronic high-pass filter that can be engaged with an external pushbutton switch. This filter smoothly rolls off low-end with a 6db/octave shelf at 283 Hz. The switch activates the KU5A’s near-field mode for optimal close-range performance. This high-pass filter was designed specifically for singers who use the KU5A on the road and in the studio, and allows its user to position the mic right up against the source without experiencing overwhelming proximity effect.
Touring bands rely on the durability and low-profile of the KU5A for sound reinforcement at live shows. At outdoor festivals and indoor theaters alike, the KU5A is perfectly equipped to bring studio sound to the live stage. Its integrated windscreen protection prevents interference at windy venues and its active electronics allow for flexibility with virtually any mixing board or audio interface.
“I dig the KU5A on snare. Beef and snap. Good rejection. Sounded real good and natural. It was all there.”
“There are very few pieces of equipment that can handle the amount of tasks I put the KU5A up against. It handled all of them effortlessly with the perfect amount of clarity and enjoyable qualities. It’s a winner, hands down.”
“We used the KU5A on cello spot on Deadpool 2’ orchestra sessions and loved it. Having a supercardioid ribbon like this opens a lot of new possibilities. You can now dig in but still get the characteristic ribbon sound.”
