The A840 is a high end Phantom-powered ribbon microphone that offers high output and immunity to impedance-loading so you have a choice of preamps to avoid noise problems in low signal level applications. This microphone combats many of the limitations of passive ribbon microphones including short cables runs or using low powered preamps.

AEA A840

This ex-demo AEA A840 is in perfect condition and shows not signs of usage, this mic is a high end Phantom-powered ribbon microphone that offers high output and immunity to impedance-loading so you have a choice of preamps to avoid noise problems in low signal level applications. This microphone combats many of the limitations of passive ribbon microphones including short cables runs or using low powered preamps.

The AEA A840 uses a big, 2.35" by 0.185" by 2 micron pure aluminium low-tension ribbon element just like the classic R44. Many ribbon mic manufacturers choose shorter ribbons that are easier to install, but AEA’s Large Ribbon Geometry TM design offers important advantages. Ribbon microphones operate linearly above their resonant frequency, unlike condenser or moving-coil transducers, so the resonant frequency of a good microphone design should be as low as possible.

AEA A840 Features

  • Phantom powered R84 with 12 dB more sensitivity
  • Custom German toroidal transformer and JFET electronics
  • Optimal for soft sound sources and classical recording
  • Same award-winning sound as the passive R84
