AEA R88 mk2 Stereo Ribbon Microphone
Your AEA R88 Blumlein Stereo ribbon mic is unlike any other coincident stereo microphone.
1. Polar patterns are consistent at all frequencies whereas directional condenser mics become
omnidirectional at lower frequencies.
2. Low frequency response extends down to 20 Hz whereas directional condenser capsules and
shorter ribbons roll off and/or eliminate lower frequencies.
3. Blumlein intensity stereo delivers a solid, stable and in-phase soundstage from their front and rear
quadrants, with an excellent sense of depth.
4. A properly positioned Blumlein pair also conveys a strong sense of spaciousness, reminiscent of
spaced omnis, which we attribute to the left and right and left quadrants being out-of-phase.

User's Manual
Thank you for choosing an AEA R88 mk2 Stereo Ribbon Mic. There is no easier
way to track natural stereo than by using a stereo mic. From drum overheads to live
concert recordings, the R88 is convenient to use and aesthetically pleasing.
The natural soundstage and character of the R88's Blumlein Stereo makes it a great
main mic. An excellent orchestral and choral recording microphone, it shines on
applications such as horn sections and drum overheads. The R88 accurately records
complex tones such as woodwinds, strings and cymbals.
The heart of the R88 are two matched native pressure-gradient ribbon transducers
tuned to 16.5 Hz. They are 1.8 micron (7/100,000 inch) thin and match the air's
acoustical impedance within 1 dB. This is a Pure Ribbon
Only black technical-fabric and stainless steel separate the ribbons from the music
AEA Big Ribbons
deliver extended highs and fast transient response without the
tm
high-frequency, high-Q resonances characteristic of tightly stretched condenser. They
are native figure-8s with exceptional imaging, transient response, and sense of space.
The figure-8 pattern is highly useful for controlling bleed and room tone.
Appreciated for What You Hear Is What you Get, Blumlein stereo is the most three
dimensional coincident recording system. The ribbons are 90 degrees to each other
for convenient Blumlein and Mid/Side (M/S) stereo. M/S is an excellent technique
for solo instruments and situations needing post-production stereo width control.

  • Page 2 The Blumlein Stereo “sweet spot” is the 90 degree angle between the principal axis of channels “1” and “2”. Instruments in this front region are in-phase and in-polarity. When placing the R88, try to position it so that instruments in front are + or - 45 degrees from the centerline. The rear “sweet spot” of an R88 is the rear 90 degree quadrant, ie + or - 45 degrees from the rear centerline.
  • Page 3 IF YOU HAVE OR USE PHANTOM POWER, READ THIS SECTION. Never patch ANY MIC through a patchbay with phantom power on. This puts 48 Volts DC across pins two and three, and magnetizes microphone output transformers. Faulty or miswired cables, or a poorly designed phantom supply can also cause such subltle magnetiation damage.
