Royer Labs SF-24V - Manual (Page 18)

Care and Maintenance
The SF-24V is a solidly built, precision instrument. Following a few commonsense rules is all
that is required to ensure proper operation of this microphone.
1. To avoid transducer damage, do not expose 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 in one or both transducers 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 blast filter when close miking a vocalist or certain types of wind instruments. P-
popping does not necessarily damage the ribbon element, but it 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 alternating electromagnetic fields, i.e. the power
transformers in amplifiers, or a 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. Use WD-40® or mineral oil to protect the finish.
6. Keep metal filings away from the microphone at all times. The SF-24V's powerful magnets
can attract minute ferrous particles into the ribbon transducers, compromising the
performance.
7. When not in use, store the microphone in its protective carrying case. If the microphone is to
remain set up on a mic stand between sessions, cover it with its mic sock (provided with your
SF-24V).
8. Leave disassembly of the microphone to a trained technician. There are no user-serviceable
parts inside the microphone or power supply.
Care for the Satin Nickel Finish
The SF-24V’s standard dull satin nickel finish is durable and easy to maintain. Simply use a soft
cloth to clean the microphone body. If needed, a small amount of denatured alcohol can be used
to remove fingerprints and other stains.
Care for the Optional Optical Black Finish
The SF-24V's optional optical black finish is a surface treatment designed to refract light rather
than reflect it. To maintain the finish, it is good practice to massage the microphone gently with a
lint free cloth treated with a few drops of light machine oil or WD-40® (apply the oil to the
