KU5A

From PMT Audio:

I think the video on this page explores why choosing a KU5A could be the right move. I would highly recommend it for a professional studio for a variety of uses to include augmenting the AEA R44 you may already have. I would especially recommend it for any situation where quality is paramount, but you have a studio where your isolation situation is still under development. So maybe voiceover or for vocals and of course for live applications. I would be happy to chat about your goals in more detail, so feel free to call. As stated in the video, I am a huge fan of all things AEA. All of the AEA microphones give you as the producer/engineer a huge degree of flexibility concerning levels in the mix.

From AEA:

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.

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.
