AEA A840

AEA A840 Active Studio Ribbon Description

Could we preserve and update that Big Ribbon™ sound in a more affordable package? Using new technologies, how much could we simplify? The A840 uses the same big ribbon as the A440, is 5 pounds lighter, and less bulky. Designed for accent and solo work, its bass proximity effect is less pronounced and the upper 10 to 20 kHz octave is stronger than the A440. Output sensitivity is quite good, which makes working in large spaces with dimmable lighting easy. The A840 active studio ribbon is a new standard of reference for large and small studios around the world.

The Big Ribbon™ sound in a smaller package

The A840 is different from other microphones. One listen and the A840 stands out with its big, clean sound. It’s an ideal spot mic with its tight pattern, smooth extended top, and less proximity bass boost than the R44 and A440. The A840 effortlessly handles a broad range of applications from accent to ensemble.

The A840 and other AEA BIG RIBBON tm mics are excellent digital recording tools. Digital has different limitations than analog. The digital recording process is more exacting as it is capable of preserving razor sharp details for generations. So it makes sense to use microphones that fit well into the final mix from the start. AEA BIG RIBBON tm mics with their smooth, natural, and easy-to-EQ sound have enjoyed a rebirth as digital recording has blossomed.

Over 30 years of servicing ribbon mics taught us what users like, and they all like the big sound of the RCA 44. Preserving and reintroducing that sound became an AEA mission. The AEA R44 and A440s, robust, heavy, and expensive to manufacture, are now in daily use worldwide. But that’s just the beginning of the story.
