Royer Labs R-122V - Manual (Page 20)

R-122V’s offset-ribbon design allows ample space for rearward excursions of the ribbon element.
However, tracking on the back side causes the ribbon to move forward towards the front side of
the microphone, where the internal dampening screen is much closer to the ribbon element.
Rear-side recordings of loud, low-frequency sounds, or vocalists with no pop filter, can drive the
ribbon into the front dampening screen, creating noise and possibly damaging the ribbon
element. Limit back side recording on your R-122V to lower SPL sound sources.
Care & Maintenance
The R-122V is a well-built, precision instrument. All that is required to ensure proper operation
of this microphone is to follow some commonsense rules.
1. Avoid transducer damage by not exposing the microphone to severe shock or vibration. If the
microphone is accidentally dropped, test it to see if damage has occurred before returning it
to service. Low output or a dull sound would indicate a stretched ribbon.
2. Do not expose the microphone to direct blasts of air or strong air currents! Use a windscreen
or suitable pop filter when close miking a vocalist or certain types of wind instruments. P-
popping does not necessarily damage the ribbon element but may produce unacceptable
preamplifier overload and could cause damage to speaker systems.
3. Do not expose the microphone to liquids or caustic smoke.
4. Do not expose the microphone to strong EMF (electro-magnetic fields), such as the power
transformers in amps, or hum may result.
5. Use a soft cloth to clean the microphone body. A small amount of denatured alcohol can be
used to remove fingerprints and other stains.
6. Keep metal filings away from the microphone at all times. The R-122V’s strong magnets can
attract even the smallest metal particles into the ribbon transducer, which can result in
compromised performance and the need for a re-ribbon.
7. When not in use, store the microphone, power supply and cabling in it’s protective case.
8. Leave disassembly of the microphone to a trained technician. Disassembly of the microphone
will void your warranty. There are no user-serviceable parts inside.
9. The R-122V’s power supply has no user serviceable parts inside so do not attempt to make
repairs. There are lethal voltages present that can cause serious injury if mishandled. Leave
servicing to a qualified electronic technician.
The vacuum tube located inside the microphone body is a sub-miniature type that is
permanently wired into place. The mil-spec 5840 tube has a minimum service life of over
20
