The AEA A840 is an active ribbon microphone using AEA’s Large Ribbon Geometry design found on the R84 and JFET amplifier circuit.
The AEA A840 features the same 1.8 micron aluminium ribbon element tuned to 16.5Hz as in the R84 but uses a transformerless amplifier circuit design conceived by Fred Forsell and requires phantom power. The ribbon is centred in a magnetic gap but is designed to produce slight different tonalities from the front and the rear of the microphones offering a choice of two colours. The rear side can also be used to handle plosives better.
Its JFET impedance buffer circuitry allows the A840 to be used with lower preamp impedance without affecting the sound while the high output sensitivity reduces noise considerably and permits long cable run. You can therefore use any valve mic pre or any mic pre of your choice adding further colouration to your chain.
The A840 is ideal for digital recording setups, offering a smoother, more natural sound than condenser microphones helping you to capture a smooth, and easy to EQ sound. Designed for vocals and accent work, the A840 has a smaller proximity effect and improved 10 to 20kHz frequency-response than the A440.
