AEA KU4 Passive Ribbon Microphone

With a supercardioid polar pattern, rich ribbon tone, and extended top-end, the KU4’s directionality allows it to be positioned almost anywhere without capturing room tone and bleed, making it one of the most flexible ribbon mics in production today.

KU4 OVERVIEW:

- Supercardioid polar pattern, rejecting bleed and ambient room reflections
- Extended top end with classic ribbon smoothness
- Near-field ribbon mic with reduced proximity effect for close-miking
- AEA’s redesign of RCA’s legendary KU3A
- Made in the USA

AEA’s KU4 is one of the most useful and unique ribbon microphones in the world. Its supercardioid polar pattern rejects bleed from other instruments and reflections in the room while retaining matchless top-end clarity. As the brightest mic in the AEA line, it retains the full spectrum sonic range that has made ribbon mics a staple in most of the world’s great recording studios.

The KU4’s minimal proximity effect and accented mid-range make it an exceptional vocal mic that captures the presence and detail of a performance. Its near-field nature also lends to the close range recording of kick drums, strings, and woodwinds, providing a welcome brightness and balance in the mix.

The KU4’s supercardioid polar pattern enables it to capture direct sound from a vocalist or instrument without room tone. This is an advantage when tracking musicians live in the same room or when used live on stage. With most figure-of-eight patterned ribbons, mic positioning can require a finesse to avoid other sources using the microphone’s nulls. The KU4 has none of these limitations.
