Active Version of a Classic Ribbon Favorite

Get to know them!

The exciting R84A is an active version of AEA's acclaimed R84 microphone. Now, you can get that luscious ribbon sound, only with the benefit of a hotter signal that gives you a lot more versatility in terms of how you use it and what preamplifier you use it with. With an outstandingly clear, natural sound, the R84A is going to become your first-call pick on a number of sources, from vocals to brass instruments to strings, piano, percussion, and beyond. When you want that big, velvety ribbon sound, you won't believe your ears when you hear the AEA R84A.

What the R84A can do for you

If you regularly encounter harsh-sounding or overly bright sources, the AEA R84A is your new best friend. It works wonders, smoothing out and taming overly bright cymbals, shrill horns, and sibilant singers. Kicking in around one foot from the source, the R84A's proximity effect is less pronounced than other mics, so you can get in close on guitar cabs and use it on vocalists with a penchant for hugging the mic. The R84A delivers the same huge, award-winning sound as the R84, with just a bit more top end. Whether your recording tasks include massive-sounding drums or a symphony orchestra, the R84A will do you proud.

Big ribbon = big sound

The R84A employs AEA's 1.8-micron pure-aluminum ribbon element. Many ribbon mic manufacturers use shorter ribbons for ease of installation, but AEA’s Large Ribbon Geometry design delivers important advantages. In contrast to condenser or moving-coil transducers, ribbon mics operate linearly above their resonant frequency, which implies that the resonant frequency of a superior microphone design should be as low as possible. And the longer the ribbon, the lower the resonant frequency. As the ribbon vibrates within the magnetic gap, it must move twice as far for every octave drop; hence, a longer ribbon allows for further back-and-forth movement.

So far, we've established through physics that larger ribbons handle louder sound sources and higher sound pressure levels. AEA tunes most of its ribbons to 16.5Hz, and as the R84A shares the same Big Ribbon as the rest of the company's product range, it captures a smooth, natural, life-sized sound free of the resonance malfeasance that shorter ribbons and condensers may exhibit. The result is a true rendition of the source that engineers agree is remarkably close to what they hear when out in the tracking room.

Classic sound meets cutting-edge tech

Back in the day when RCA ruled the roost, ribbon microphones were, by definition, passive transducers. Along came the transistor and the accompanying miniaturization of electronic components, enabling the deployment of ribbon mics in even more applications. To achieve optimal performance, a passive ribbon microphone needs to be matched with a high-impedance, high-gain preamp. But you can use active (phantom-powered) ribbon microphones like the R84 with a broader range of preamps, including those typically found in USB audio interfaces. A Sweetwater tip is in order here: This does not mean that passive ribbon mics are obsolete relics! Passive ribbons still beat out actives when it comes to maximum signal level (165dB vs. 141dB SPL) and a minimalist signal path.

World-class sonic performance and versatility

The R84A exhibits the same award-winning sonic prowess as its passive stablemate, the R84. But thanks to its higher output and immunity to impedance loading, it eliminates low-signal-level noise and gives you more flexibility in your preamp choice. The R84A rectifies most of the limitations of passive ribbon mics, whether in an orchestral setting, in remote recording applications with long cable runs, or simply when combining the smooth sound of a ribbon with a low-gain vintage preamp. Bolstered by the signal strength and versatility of its active JFET electronics, combined with the posh warmth of AEA's Big Ribbon, the R84A is a must-have for any well-equipped studio. And owning a pair of them vastly increases the versatility of this outstanding microphone, opening up highly effective stereo recording techniques such as Blumlein.

AEA R84A Features:

  • Phantom-powered (48V) version of AEA's classic R84 ribbon microphone with 12dB more sensitivity
  • Same award-winning sound as the passive R84
  • Well-controlled figure-8 polar pattern
  • Compatible with any preamp and input impedance
  • Fast, accurate transient reproduction
  • Custom German toroidal transformer and JFET electronics
What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
