AEA KU4 Shop all AEA Microphones

The KU4 is AEA's version of the rare RCA KU3A, one of the most impressive microphones in recording history. With less than 600 units ever built, the KU3A is super hard to find and can command extermely high prices in the used market. Enter the KU4.

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.
