AEA R88

Passive stereo ribbon: two matched figure-8 Big Ribbons in a fixed Blumlein pair (current version R88mk2)

Approximate Some readings for this mic are uncertain; see the graphs.

Power None (passive). Switch phantom power off before you plug it in: a faulty cable can damage the ribbon. Low output: it needs a lot of preamp gain.

Sensitivity
−52 dBV/Pa
vs 24 side-address ribbons

More output than 35% of 24 side-address ribbons.

Each stripe is one side-address ribbon with a published sensitivity, and each bar counts them; further right means more output. This mic is in blue.

  • Among 28 ribbons: more output than 41%
  • Among 311 mics: more output than 26%
Max SPL
165 dB SPL
vs 28 side-address ribbons

Takes louder sound than 85% of 28 side-address ribbons.

Each stripe is one side-address ribbon with a published max SPL, and each bar counts them; further right means it takes louder sound. This mic is in blue.

  • Among 29 ribbons: takes louder sound than 86%
  • Among 343 mics: takes louder sound than 99%
