1. Introducere
The AEA R84 is a passive ribbon microphone designed for professional audio recording. It is recognized for its natural sound reproduction and figure-8 directional sensitivity, making it suitable for a wide range of recording applications, including solo instruments and accent work. This manual provides essential information for the proper setup, operation, and maintenance of your R84 microphone.
2. Produs terminatview
The AEA R84 features a large, low-tension ribbon element (2.35" by 0.185" by 2 micron pure aluminum) which contributes to its outstanding transient response. This design ensures accurate and clean reproduction of percussive attacks, vocal consonants, and other rapid-onset sounds without introducing undesirable characteristics. The microphone's figure-8 polar pattern captures sound from both the front and rear, while rejecting sounds from the sides.

Caracteristici cheie:
- Large Ribbon Geometry (LRG) for natural sound.
- Bidirectional (Figure-8) polar pattern.
- Robust construction suitable for studio environments.
- Includes a carrying case for protection and transport.
3. Configurare
- Despachetarea: Carefully remove the R84 microphone and its accessories from the carrying case. Inspect for any visible damage.
- Montare: Securely attach the microphone to a sturdy microphone stand using the integrated shockmount. Ensure the microphone is stable and positioned correctly for your recording application.
- Conexiune: Connect the R84 microphone to a high-quality microphone preamplifier using a balanced XLR cable. The R84 is a passive microphone and does not require phantom power. Applying phantom power to a passive ribbon microphone is generally not recommended and can potentially cause damage if wiring is incorrect, though modern designs often incorporate protection. Always verify your preamp setări.
- Câștigă Staging: Ribbon microphones typically have a lower output level compared to condenser microphones. Ensure your preamplifier provides sufficient clean gain to achieve optimal signal-to-noise ratio without introducing excessive noise.
4. Funcționare
Plasarea microfonului:
The R84's figure-8 polar pattern captures sound from the front and rear of the microphone, while rejecting sound from the sides. This characteristic is useful for:
- Stereo Recording: Two R84 microphones can be used in a Blumlein pair configuration for natural stereo imaging.
- Room Ambience: Capturing the natural acoustics of a recording space.
- Vocal/Instrument Isolation: Minimizing bleed from adjacent sound sources by positioning the nulls (sides) towards unwanted sounds.
Gain Considerations:
Due to its passive design, the R84 requires a preamplifier cu ample, clean gain. If your preamplifier struggles to provide enough gain without becoming noisy, consider using an inline microphone activator (e.g., a Cloudlifter) to boost the signal before it reaches the preamp. This can significantly improve the signal-to-noise ratio.
5. Întreținere
- Depozitare: Always store the R84 in its protective carrying case when not in use. This protects the delicate ribbon element from dust, debris, and physical shock.
- Manipulare: Handle the microphone with care. Avoid dropping it or subjecting it to strong vibrations, as this can damage the ribbon.
- Protectie impotriva vantului: When recording, especially outdoors or with strong vocalists, use a pop filter or windscreen to protect the ribbon from strong air blasts, which can stretch or tear the ribbon.
- curatenie: Clean the exterior of the microphone with a soft, dry cloth. Do not use liquid cleaners or solvents, as they may damage the finish or internal components.
6. Depanare
- Fără sunet:
- Check all cable connections (microphone to preamp, preamp to interface/mixer).
- Asigurați-vă că prealabilamplifier is powered on and gain is set appropriately.
- Verify input selection on your audio interface or mixer.
- Low Output/Noisy Signal:
- Creșteți preampcâştig lifier.
- Consider using an inline microphone activator for additional clean gain.
- Ensure no phantom power is accidentally engaged on the preamp, as this can sometimes cause issues with passive ribbon mics if not properly protected.
- Sunet distorsionat:
- Reduceți preamplifier gain to prevent clipping.
- Ensure the sound source is not excessively loud for the microphone's capabilities.
