Page 2: Welcome
Your R88 Series microphone is 100% handcrafted in Pasadena, CA. AEA is a family owned company with a small crew of skilled technicians – most of them being musicians themselves. Proudly independent, we still manufacture all our ribbon microphones and preamps by hand from locally sourced parts. -

R88A uses the same 1:110 transformer and electronics used in our active mics. With the great bass response and smooth top end AEA Big Ribbons are known for, the R88 Series delivers a solid sound stage without ever being harsh. The R88 operates with very... -

R88A Phantom-Powered Microphone The phantom current draw for active AEA ribbon mics is 7 milliamps. IEC specifies P48 power which should be able to deliver 10 milliamps per input. Some USB and battery-powered audio interfaces will not deliver this. - Page 6 For long term storage, place the microphone in its protective case. Minute iron particles, sometimes known as “tramp iron,” are common within our environment. AEA ribbon microphones contain powerful magnets that produce strong magnetic fields. These fields can attract any ferric metal near the microphone that, if they are small enough, can penetrate the outer screening and work their way inside the microphone.
- Page 7 +60dB or higher. To guarantee consistent, full-range ribbon sound, we recommend AEA’s RPQ2, RPQ500 and TRP2 preamps, which were specially designed for ribbon microphones. On quiet sound sources or for distance recording, an AEA preamp is highly recommended.

APPLICATIONS ADVICE We actively encourage users to visit AEAribbonmics.com access our comprehensive collection of in-depth articles and tutorials featuring the R88 stereo microphone, along with a library of audio and video demonstrations of the R88 in action. A FIGURE-OF-8 MICROPHONE Figure-of-8 microphones are constructed with positive polarity on the front and negative polarity on the back. - Page 9 1 and 2 bisect. When placing the R88, position it so that the instruments are + or - 45 degrees from the centerline. Align the AEA logo and vertical marks with the instrument or ensemble you are recording.
- Page 10 The left and right quadrants are the “out-of-polarity” zones of the microphone. This is because the positive lobe of one transducer is in one channel and the negative lobe of the second transducer is in the other channel. Sources recorded in this area make the listener want to turn their head, because the polarity in one ear is off.
- Page 11 USING THE R88 IN M/S The R88 also works well with Mid-Side, or M/S, recording. M/S is worth experimenting with as it has the ability to control the stereo width by varying the Mid to Side ratio. This is especially convenient when recording a solo sound source where the emphasis on the center of the stereo image.
- Page 12 PROXIMITY EFFECT (graph is a visualization, not a measurement) Proximity effect is a characteristic of all directional microphones; it is a rise in low-frequency response that increases at closer working distances. While this can be used to good effect, particularly with low-register voices to give them an enhanced richness and depth, the potential trade-off is reduced articulation or clarity that can result from the masking effect on the treble due to “excessive”...
