R84A 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.

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.

The high-performance magnets used in AEA microphones are incredibly strong, and a significant amount of stray magnetic field lines surround the microphone. Avoid placing the microphone in close proximity to hard drives, credit cards, analog tape, or any other magnetically sensitive items to prevent any data loss.

other, they introduce their own set of problems - not the least of which are reflections in close proximity to the performers and/ or microphones that result in comb-filter distortions. Since gobos usually are bulky, they also inhibit the ability of the musicians to hear and see each other easily.
The R44’s proximity effect begins at six feet (1.8 M) and can become huge. The RCA 44 was developed when studios were larger and mics were rarely used close up. Compared to the R44, the R84 has a more moderate proximity effect. Designed to accommodate both distant and medium miking duties, it exhibits a flat frequency response when placed 3 feet (1 meter) away from the source.
SPECIFICATIONS Operating Principle: Pressure gradient transducer Directional Pattern: Bidirectional Frequency Range: <20 Hz to >20 kHz Polarity: Pin 2 high for positive pressure on front of microphone Polar Response: Native bidirectional, figure-of-8 pattern Horizontal: Up to 90 dB rejection at right angles to the front/back axis.
