  • Page 4: Introduction

    With improvements in ribbon technology and manufac- turing since the 30’s and 40’s, AEA engineered the R84 to be more efficient, lighter and less expensive. Designed to accommodate distant and medium miking duties, it exhibits a flat frequency response when placed 3 feet (1 meter) away from the source.

  • Page 5: Application Advice

    APPLICATION ADVICE “This Side” vs. “That Side” Here is an illustration of the pickup pattern of the R84. The AEA logo on the front of the R84 points directly towards the ‘principal axis’ (+) indicated in the diagram.

  • Page 6: Controlling Leakage

    Since the R84 is bidirectional, it exhibits nulls at right angles to the principal axis. These nulls produce a “plane of rejection” around the sides, top and bottom of the mic that can be used effectively to reduce leakage.

  • Page 7: Preamps

    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. The R84 has a more moderate proximity effect, better suited for closer use in contemporary studios. Designed...

  • Page 8: Application Examples

    Vocals Our experience with the R84 is that it sounds best on vocals when used at a distance of 6 to 24 inches (15-60 cm). However, you may find that positioning the microphone closer or further away from the singer yields better results depending on the voice, the room or the musical style.

    R84 at an angle. You will find that small differences in positioning can make huge differences in the sound, so experiment until you find the spots you like. Close up, the R84 is very good at spotlighting a speaker’s unique sounds at various locations.

    (1-2 m) on axis towards the sound hole. To achieve a balanced string group sound, try placing the R84 5 to 8 feet (2-3 m) away (either in front or above) from the section. Use the R84’s exceptional null points to isolate the R84’s pick up from other sources.

    For mono drum room, start by positioning your R84 at head level 9 feet (3 m) in front of the kit. Depending on the size of the room and kit arrangement, you may want to position the R84 further away if you wish to capture more room ambiance.

  • Page 13: Tramp Iron

    The best prevention is to keep the microphone covered with the supplied plastic bag when it is not in use. The R84 was designed to be less sensitive to external interference. Its design attracts less “tramp iron” while retaining the overall sound and 20 Hz bass response of the original RCA 44.

  • Page 14: Microphone Positioning

    Guitar players will know this phenomenon from single-coil pickups. Even though much attention was paid to suppressing such sensitivity to external magnetic fields in the design of the R84, it is still possible that you might encounter this problem. If you should pick up...
