AEA A840 Active Ribbon Microphone Introduced by Wes Dooley at AES, October 2009

Ribbon Microphone Wizard Wes Dooley introduces the world to the new A840 Active Ribbon Microphone at the New York City AES (Audio Engineering Society) Exhibits October, 2009. Designed to be a cross between a more affordable A440 Active Big Ribbon Mic (AEA's other active ribbon, also the quietest and most detailed ribbon microphone ever produced, but with a $5k price tag), and the R84 affordable ribbon (that sounds incredibly warm and smooth but requires tremendous preamp gain, this new A840 is destined to be a tremendous success... it's street price is designed to be well under 2-grand. Loads of detail, dynamic range (high SPL of 141 dB and low self noise of 17.5 dB), and the famous AEA ribbon sound will make this extremely versatile and user friendly even on acoustic instruments where it's tougher to make traditional ribbons operate. Hugely wide frequency response add to the fact that this microphone is going to be versatile accross the studio and orchestra.

Manufacturer's Description from AEA

For those without access to an ideal preamp, AEA offers the Active R84A (formerly known as the A840), a premium version of the R84 complete with JFET electronics and the same custom transformer used in our active R44. It’s basically an R84 with a built-in preamp.

The active R84A mic retains the same sonic character of the R84, but with an additional 12dB of output and a stable impedance. This gives a consistent frequency response and greater flexibility with different preamps, including those found in audio interfaces for personal computers. This is great for on-the-road musicians who might have to use a different preamp each night.

The extra 12db of output is vital when recording quiet sources like vocals or soft acoustic guitars. The active circuitry also prevents noise interference on long cable runs or when operating near large lighting rigs. The R84A’s active circuitry requires standard 48-volt phantom power to operate. The premium R84A also flaunts an 18-karat, gold-plated grille.

 

Included:

Softcase, user manual, captive 10” (3 meter) output cable with XLR-3M connector.

About Manufacturer

Wes Dooley's longtime passion for audio has infused his company, Audio Engineering Associates (AEA), with a well balanced blend of creativity and technical expertise for forty years. At the core of AEA is a genuine interest in the art and science of audio. From areas as diverse as forensic audio and microphone design, Wes' passion for audio has led him all over the world, from recording experiences in Europe, Africa, and New Zealand, to the courtrooms of Los Angeles as a forensic audio and video expert witness. Such experiences have led Wes to design products which help resolve problems commonly encountered by recording engineers. His portable recording tools including, multi-channel microphone arrays, MS stereo processors, stereo phase displays and very tall microphone stands, have all made on-site recording far more feasible. Despite his contributions to on-location recording, Wes is best known for his pursuit of excellence in ribbon microphone technology. After two decades of representing and servicing the BBC 4038 in the United States, he began to experiment with his own ribbon microphones. During the last decade Wes became aware of the increasing scarcity of R44's and other ribbon microphones. In 1998, responding to this need, Wes re-introduced the 44 much to the thrill of many in the recording industry. Les Paul told Wes that AEA's R44 is his favorite microphone and engineer/producers such as Bruce Swedien, Kevin Bacon, and Shawn Murphy routinely use AEA's R44. Even without such critical acclaim the numbers speak for themselves. Over half of the movies scored in Los Angeles have a 44 somewhere on the scoring stage. Building off of his successful reintroduction of the R44, in 2002 Wes designed and began producing an original ribbon mic, the AEA R84. His groundbreaking work with ribbon microphones helped him to secure the Audio Engineering Society (AES) Silver Medal Award in the fall of 2003. This award, established by the AES in 1971, in honor of audio pioneers Alexander Graham Bell, Emile Berliner, and Thomas A. Edison, is given in recognition of outstanding development or achievement in the field of audio engineering. Wes has also co-authored two AES Journal articles about stereo microphone techniques, chaired workshops on mic techniques and mixing strategies for compatible multiple releases for cinema, broadcast and home video, and has presented section meetings on stereo techniques and forensic audio. He is involved with AES standards work and currently serves on the SC-03-12 Working Group on Forensic Audio and SC-04-04 Working Group on Microphone Measurement and Characterization.
